Replication data for "Crowd-Sourced Chinese Genealogies as Data for Demographic and Economic History" (ICPSR 250178)

Released/updated on: 2026-08-05
Time period: 1600-01-01--1900-12-31
This collection contains the code, de-identified analysis inputs, and documentation needed to reproduce the tables and figures for “Crowd-Sourced Chinese Genealogies as Data for Demographic and Economic History.” The study evaluates whether crowd-sourced Chinese genealogical records can reproduce established demographic patterns and support regression-based research in economic history.The underlying source compilation contains 192,310 unique individuals associated with 535 family roots, spanning many centuries and all provinces of China. The records were harvested from the FamilySearch Family Tree, reconnected into multigenerational pedigrees, de-duplicated, and geocoded to county-level administrative units. The analysis documents population growth, sex ratios, and migration, compares these patterns with benchmarks from Chinese historical demography, and presents regressions relating province-century sex ratios to recorded childlessness and patrilineal generation depth to out-migration.The deposit contains de-identified analysis inputs derived from these records: aggregated files for cell-level analyses and record-level files retaining only the variables required for the documented specifications. Personal names, full relationship records, original person-level FamilySearch identifiers, and crosswalks to the original identifiers are not included because FamilySearch terms restrict redistribution of harvested person and relationship records. The included Stata and Python scripts reproduce the deposited tables and figures from these analysis inputs. Appendix Figure A.1 and externally sourced benchmark tables are not included.

World Migration Matrix, 1500-2000 (ICPSR 250025)

Released/updated on: 2026-06-19
The matrix gives, for each of 165 countries, an estimate of the proportion of the ancestors in 1500 of that country's population today that were living within what are now the borders of that and each of the other countries. The matrix itself is an Excel spreadsheet. Accompanying documents are a Main Appendix, providing an overview of the information and its sources, and region appendices for Africa, Americas , Asia, Europe, and Oceania , which include a one paragraph or one page explanation of the estimate for each individual country. The first version of the data set was completed in March, 2007. Revisions of some entries, mainly of countries in the Americas, using information from genetic studies to estimate the ancestry of large groups of mixed origin, were completed in August, 2009 and are incorporated in the new matrix version labeled 1.1. Links to both original and new versions of those files that have undergone change are found below.

Survey of Trauma, Resilience, and Opportunity among Neighborhoods in the Gulf: Risk Perceptions and Decision-Making During Hurricanes Helene and Milton (ICPSR 241089)

Released/updated on: 2026-02-23
Time period: 2024-09-26--2024-10-09
This study is a follow-on to the STRONG study, which assesses trauma, resilience, and opportunity among populations in the Gulf Coast; this study focuses specifically on risk perceptions and decision-making during hurricanes Helene and Milton, which impacted the Gulf Coast region in September and October of 2024. Hurricanes Helene and Milton are poignant examples of the increasing threats to the U.S. Gulf Coast from extreme weather events. The frequency and severity of such disasters has increased in recent decades, and sea levels are projected to rise along U.S. coastlines in the coming decades, with the highest anticipated increase in the Gulf Coast. Moving forward, residents of coastal, disaster-prone areas will have to make decisions about how to protect themselves in the face of this increasing risk, including whether to evacuate during hurricanes (a frequent occurrence along the Gulf Coast) or permanently migrate from the region. In this study, we fielded a new survey to an existing longitudinal study to understand how prior disaster experience and losses, mental models, risk perceptions, and other factors are related to relocation decisions. We focused on capturing ephemeral psychological and contextual states to address questions regarding mental models of changing risks, how this affects risk perception, and ultimately how these tie to protective action or inaction.

Brain Gain in Late Colonial Indonesia: New Evidence on Chinese Migration and Wages (ICPSR 242405)

Released/updated on: 2026-01-05
Geographic coverage: Indonesia
Time period: 1897-01-01--1920-12-31
This is the replication package for Hup, Mark and Pim de Zwart. "Brain Gain in Late Colonial Indonesia: New Evidence on Chinese Migration and Wages", Journal of Economic History.Abstract: During the "Age of Mass Migration", many Chinese migrants came to colonial Indonesia. We find that these migratory flows included many skilled workers, contrary to the belief that they mostly consisted of unskilled labourers. We construct a new dataset of migration and potential surplus earnings for different types of work for the period ca. 1900-1920. Our analyses show that high earnings for skilled work, but not for unskilled work, strongly incentivized migration. Given the scarcity of skilled labour in Indonesia, the skilled migrants may have significantly contributed to economic growth in general and the growing trade-based sectors in particular.

Circuits of Hope and Disillusionment: Migration Experiences of Türkiye’s Irregular Migrants to EU (ICPSR 235021)

Released/updated on: 2025-07-02
This article explores the migration journeys and return experiences of Turkish nationals who attempted to reach Europe through both regular and irregular means but ultimately returned to Türkiye. Drawing on a mixed-methods approach combining structured surveys and in-depth qualitative interviews, the study examines migrants’ motivations, imaginaries of Europe, decision-making processes, modes of travel, and the multifaceted realities of return and reintegration. The findings reveal that migration decisions are deeply embedded in socio-economic structures and collective aspirations, while also constrained by global mobility hierarchies and legal regimes. Participants often envisioned Europe through idealized lenses shaped by social networks and digital media, yet their lived experiences frequently fell short of these expectations, prompting return due to legal precarity, socio-economic hardship, or disillusionment. By centering returnee narratives, the study challenges linear understandings of migration as a unidirectional process and highlights the circular, negotiated, and often ambivalent nature of return. In doing so, it contributes to critical debates on irregular migration, return dynamics, and transnational social imaginaries, with implications for more responsive and humane migration and reintegration policies.

Longitudinal Survey Data of Households in Ouro Preto do Oeste, Rondonia, Brazil, 1996-2019 (ICPSR 213322)

Released/updated on: 2024-12-19
Geographic coverage: Brazil, Rondônia, Brazil
Time period: 1996-09-01--1996-12-31, 2000-09-01--2000-12-31, 2005-09-01--2005-12-31, 2009-09-01--2009-12-31, 2019-09-01--2019-12-31
Tropical deforestation is a striking form of land cover transformation resulting in a complex mosaic of shifting land-use patterns across space and time. Research on the underlying causes of forest conversion and the environmental consequences has been prolific, yet few scholars have assessed long term impacts on the socio-economic welfare of the frontier inhabitants along with the reciprocal effects of income and wealth on land use. Moreover, limited research addresses the impacts of these post-deforestation trajectories on employment, migration, and inequality. These lacunae are directly related to the difficulty of obtaining the spatial panel data required to track and evaluate these dynamic processes. Nevertheless, as the “old frontier” expands in tropical forest zones, it becomes critical to understand the dynamic economic and landscape processes that follow deforestation. This dataset provides opportunities to address these issues by adding a fifth round to a previous spatial panel survey of farm households in the heavily deforested state of Rondônia, Brazil.

Forecasting bilateral asylum seeker flows with high-dimensional data and machine learning techniques (ICPSR 198322)

Released/updated on: 2024-08-05
We develop monthly asylum seeker flow forecasting models for 157 origin countries to the EU27, using machine learning and high-dimensional data, including digital trace data from Google Trends. Comparing different models and forecasting horizons and validating out-of-sample, we find that an ensemble forecast combining Random Forest and Extreme Gradient Boosting algorithms outperforms the random walk over horizons between 3 and 12 months. For large corridors, this holds in a parsimonious model exclusively based on Google Trends variables, which has the advantage of near real-time availability. We provide practical recommendations how our approach can enable ahead-of-period asylum seeker flow forecasting applications.

COVID-19 High Frequency Phone Survey of Households, Ethiopia, 2020-2021 (ICPSR 38419)

Released/updated on: 2022-06-15
Geographic coverage: Ethiopia
Time period: 2020-01-01--2021-12-31

The potential impacts of the COVID-19 pandemic in Ethiopia are expected to be severe on Ethiopian households' welfare. To monitor these impacts on households, the team selected a subsample of households that had been interviewed for the Living Standards Measurement Study (LSMS) in 2019, covering urban and rural areas in all regions of Ethiopia. The 15-minute questionnaire covers a series of topics, such as knowledge of COVID and mitigation measures, access to routine healthcare as public health systems are increasingly under stress, access to educational activities during school closures, employment dynamics, household income and livelihood, income loss and coping strategies, and external assistance.

The survey is implemented using Computer Assisted Telephone Interviewing, using a modular approach, which allows for modules to be dropped and/or added in different waves of the survey. Survey data collection started at the end of April 2020 and households are called back every three to four weeks for a total of seven survey rounds to track the impact of the pandemic as it unfolds and inform government action. This provides data to the government and development partners in near real-time, supporting an evidence-based response to the crisis.

The sample of households was drawn from the sample of households interviewed in the 2018/2019 round of the Ethiopia Socioeconomic Survey (ESS). The extensive information collected in the ESS, less than one year prior to the pandemic, provides a rich set of background information on the COVID-19 High Frequency Phone Survey of households which can be leveraged to assess the differential impacts of the pandemic in the country.

Time period: 2019-01-01--2020-12-31
This digital collection is the result of research that examines the effects of nativity and legal status on the labor market prospects of Latino students exiting higher education. Specifically, this project tests in a field and survey experimental framework whether and how employers screen Latino male student job applicants based on nativity and legal status for entry-level employment positions. This project includes all the instruments, protocols, documentation, and data for other scholars interested in experimental design to replicate the results, adapt them for use in other contexts, or expand them to other treatments. The project also includes other forms of writing, which will continue to be updated, for colleges, companies, and non-profit organizations to learn more about hiring rights, diversity, equity, and inclusion, and the school-to-work transition.There are two main objectives for the societal impacts of this project. The first is to enable scholars from a wide variety of disciplines to easily access and utilize these documents, whether that be to adapt them for their own purpose, or expand them to other labor market, schooling, or treatment contexts. The second objective is to enable institutions of higher education, immigrant-serving organizations, companies, and students to easily learn from the results.

How the 1906 San Francisco Earthquake Shaped Economic Activity in the American West (ICPSR 119841)

Released/updated on: 2020-06-11
Geographic coverage: Nevada, United States, United States, Oregon, United States, California, United States
Time period: 1870-01-01--1970-12-31
Replication package for "How the 1906 San Francisco Earthquake ShapedEconomic Activity in the American West" by Philipp Ager, Katherine A. Eriksson, Casper Worm Hansen and Lars Lønstrup. We refer to the paper, and its Online Appendix, for further details on data sources and how results are obtained. Please see the "read me.rtf" for further instructions.

Abstract:This paper examines the long-run effects of the 1906 San Francisco Earthquake on the spatial distribution of economic activity in the American West. Using variation in the potential damage intensity of the earthquake, we show that more severely affected cities experienced lower population increases relative to less affected cities until the late 20th century. The earthquake left a long-lasting mark mainly because it interrupted existing migrant networks. Less affected areas became more attractive migrant destinations in the immediate aftermath of the earthquake, which permanently changed relative city sizes in the American West.

Tsogolo La Thanzi (TLT): Migration Autopsy Data, Malawi, 2009-2012 [Healthy Futures] (ICPSR 37190)

Released/updated on: 2018-12-10
Geographic coverage: Balaka, Malawi, Africa
Time period: 2009-01-01--2012-12-31

The Tsogolo La Thanzi (TLT): Migration Autopsy collection contains data collected as part of the Tsogolo la Thanzi (TLT) Study. TLT is a longitudinal study in Balaka, Malawi designed to examine how young people navigate reproduction in an AIDS epidemic. Tsogolo la Thanzi means "Healthy Futures" in Chichewa, Malawi's most widely spoken language. New data is being collected to develop better understandings of the reproductive goals and behavior of young adults in Malawi -- the first cohort to never have experienced life without AIDS. To understand these patterns of family formation in a rapidly changing setting, TLT used the following approach: an intensive longitudinal design where respondents are interviewed every fourth months at TLT's centralized research center.

The Migration Autopsy collection contains many TLT respondents whom moved away during the study period. In order to both carefully track attrition and gather valuable information about migration, TLT performed a migration autopsy on study participants who migrated from the study area during the course of the 8-wave observation period. Data collection began in April of 2009 and was completed in December of 2012. To assess changes on a longer time-horizon, a follow-up survey we refer to as Tsogolo la Thanzi 2 (TLT-2) was fielded between June and August of 2016.

Eurobarometer 84.1: Parlemeter, September 2015 (ICPSR 36668)

Released/updated on: 2017-12-07
Geographic coverage: Cyprus, Portugal, Malta, Greece, Netherlands, Sweden, Great Britain, Austria, Latvia, Luxembourg, Ireland, Poland, Slovenia, Slovakia, France, Bulgaria, Lithuania, Croatia, Romania, Hungary, Northern Ireland, Spain, Czech Republic, Belgium, European Union, Finland, Denmark, Italy, Germany, Estonia
Time period: 2015-01-01--2015-12-31

The Eurobarometer series is a unique cross-national and cross-temporal survey program conducted on behalf of the European Commission. These surveys regularly monitor public opinion in the European Union (EU) member countries and consist of standard modules and special topic modules. The standard modules address attitudes towards European unification, institutions and policies, measurements for general socio-political orientations, as well as respondent and household demographics. The special topic modules address such topics as agriculture, education, natural environment and resources, public health, public safety and crime, and science and technology.

This round of Eurobarometer surveys covers the following topics: (1) Attitudes and knowledge regarding the European Parliament, (2) Opinions on the EU, and (3) Migration. Respondents were asked about their trust in the Parliament and EU membership, their knowledge of the EU, level of interest in European affairs, and EU laws. People were asked to give their opinions on the EU, such as European Identity, important aspects of strengthening the EU, and assessment of their own countries membership. Migration, asylum seekers, legal procedures, and attitudes towards citizens of other member states were also topics of questions.

Demographic and other background information collected includes age, gender, nationality, marital status, occupation, age when stopped full-time education, household composition, ownership of a fixed or mobile telephone and other goods, difficulties in paying bills, level in society, and Internet use. In addition, country-specific data includes type and size of locality, region of residence, and language of interview (select countries).

Current Population Survey: Annual Social and Economic (ASEC) Supplement Survey, 2015 (ICPSR 36525)

Released/updated on: 2016-10-25
Geographic coverage: United States
Time period: 2014-01-01--2015-12-31

The Annual Social and Economic (ASEC) 2015 Supplement is part of the Current Population Survey (CPS) Series. The CPS is a source of the official Government statistics on employment and unemployment. The Census Bureau conducts the ASEC (known as the Annual Demographic File prior to 2003) over a three-month period, in February, March, and April, with most of the data collected in the month of March. The ASEC uses two sets of survey questions, the basic CPS and a set of supplemental questions.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage, and salaried employees, and estimates of total unemployment.

In addition to the basic CPS questions, respondents were asked questions from the ASEC, which provides supplemental data on poverty, geographic mobility/migration, and work experience. Comprehensive work experience information was given on the employment status, occupation, and industry of persons aged 15 and over. Additional data for persons aged 15 and older were available concerning weeks worked and hours per week worked, reason not working full-time, total income and supplemental income components. Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income. Data on employment and income refer to the previous calendar year, although demographic data refer to the time of the survey.

The occupation and industry information variables in this data collection can help the data users identify individuals who worked in arts and culture related fields. The occupations are listed in a category entitled "Arts, Design, Entertainment, Sports, and Media Occupations," which includes professions such as artists, designers, actors, musicians, and writers (see Appendix B of the User Guide for further category details). Industries related to the arts and culture are in the "Arts, Entertainment, and Recreation" category (see Appendix C of the User Guide for further category details).

The ASEC data provided by the Census Bureau are distributed in a hierarchical file structure, with three record types present: Household, Family, and Person. The ASEC is designed to be a multistage stratified sample of housing units, where the hierarchical file structure can be thought of as a person within a family within a household unit. Here the main unit of analysis is the household unit.

Longitudinal Study of the Second Generation in Spain (ILSEG) (ICPSR 36286)

Released/updated on: 2016-09-13
Geographic coverage: Barcelona, Europe, Madrid, Spain
Time period: 2007-01-01--2007-12-31
This is the publicly available version of the ILSEG data (ILSEG is the Spanish acronym for Investigación Longitudinal de la Segunda Generación, Longitudinal Study of the Second Generation). Questions address the current situation and plans for the future of young Spaniards who are children of immigrants to Spain, who were living in Madrid and Barcelona and attending secondary school in 2007-2008. The longitudinal study of the second Generation (ISLEG in its Spanish initials) represents the first attempt to conduct a large-scale study of the adaptation of children of immigrants to Spanish society over time. To that end, a large and statistically representative sample of children born to foreign parents in Spain or those brought at an early age to the country was identified and interviewed in metropolitan Madrid and Barcelona. In total, almost 7,000 children of immigrants attending basic secondary school in close to 200 educational centers in both cities took part in the study. Topics include basic demographics, national origins, Spanish language acquisition, foreign language knowledge and retention, parents' education and employment, respondents' education and aspirations, religion, household arrangements, life experiences, and attitudes about Spanish society. Demographic variables include age, sex, birth country, language proficiency (Spanish and Catalan), language spoken in the home, number of siblings, mother's and father's birth country, religion, national identity, parent's sex, parent's marital status, parent's birth year, and the year the parent arrived in Spain.

ANES 2012 Time Series Study (ICPSR 35157)

Released/updated on: 2016-05-17
Geographic coverage: United States
Time period: 2012-09-01--2013-01-31
This study is part of the American National Election Study (ANES), a time-series collection of national surveys fielded continuously since 1948. The American National Election Studies are designed to present data on Americans' social backgrounds, enduring political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. As with all Time Series studies conducted during years of presidential elections, respondents were interviewed during the two months preceding the November election (Pre-election interview), and then re-interviewed during the two months following the election (Post-election interview). Like its predecessors, the 2012 ANES was divided between questions necessary for tracking long-term trends and questions necessary to understand the particular political moment of 2012. The study maintains and extends the ANES time-series 'core' by collecting data on Americans' basic political beliefs, allegiances, and behaviors, which are so critical to a general understanding of politics that they are monitored at every election, no matter the nature of the specific campaign or the broader setting. For the first time in the ANES Time Series history, face-to-face interviewing was supplemented in 2012 with data collection on the Internet. Data collection was conducted in the two modes independently, using separate samples. While face-to-face (FTF) respondents were administered the single pre-election interview and single post-election interview traditional to Time Series presidential-election-year studies, for the internet sample the same questions were administered over a total of four shorter online interviews, two pre-election and two post-election. Web-administered cases constituted a representative sample separate from the face-to-face sample and were drawn from panel members of GfK Knowledge Networks. The face-to-face (FTF) sample of fresh cross-section cases featured oversamples of African-Americans and Hispanics. For the first time in the ANES Time Series, FTF respondents were administered CAPI interviews programmed as instruments on handheld tablets, which were employed by interviewers using touchscreen, stylus, attached keyboard or any combination of entry modes according to interviewer preference. In both the pre-election and post-election FTF interviews a special CASI (Computer Assisted Self-Interviewing) segment was conducted. In addition to content on electoral participation, voting behavior, and public opinion, the 2012 ANES Time Series Study contains questions about areas such as media exposure, cognitive style, and values and predispositions. Several items were measured on the ANES for the first time, including "Big Five" personality traits using the Ten Item Personality Inventory (TIPI), skin tone observations made by interviewers in the face-to-face study, and a vocabulary test from the General Social Survey called "Wordsum." The Post-Election interview also included Module 4 from the Comparative Study of Electoral Systems (CSES). Demographic variables include respondent age, education level, political affiliation, race/ethnicity, marital status, and family composition.

Migrations between Africa and Europe project (MAFE) (ICPSR 36206)

Released/updated on: 2015-06-15
Geographic coverage: Netherlands, Belgium, Senegal, Europe, Democratic Republic of Congo, Africa, United Kingdom, Italy, Ghana, France, Sub-Saharan Africa, Spain
The Migration between Africa and Europe (MAFE) project gathered innovative data on migration between Sub-Saharan Africa and Europe. Coordinated by INED, scientific teams in three African countries and six European countries worked together to design and carry out a multi-sited, comparative and longitudinal survey. Between 2008 and 2010, MAFE collected household surveys in the Democratic Republic of Congo, Ghana and Senegal, as well as individual biographical questionnaires in Africa (DR Congo, Ghana, Senegal) and in Europe (Congolese in Belgium and the UK; Ghanaians in the Netherlands and the UK; Senegalese in France, Italy and Spain). The individual questionnaire collects full retrospective histories of individual's housing, study and work trajectories, family formation, property ownership and migrant networks. MAFE offers a unique source of data that enables researchers to study the patterns, causes and consequences of African migration. Data collected in African countries may also be used to study other socio-demographic phenomena. MAFE offers online access to the project's background, methods (design, sampling, questionnaires, methodological notes, etc.), publications (MAFE working papers, PhD thesis, articles, etc.) and all contextual, household and individual data sets. MAFE-based research has appeared in the pages of the ANNALS of American Academy of Political and Social Science; Demography; Demographic Research; European Journal of Population; International Migration Review; Population (French and English Edition); Population, Space and Place; and World Development, among others.

TAZAMA Health and Demographic Surveillance System, 1994-2012 (ICPSR 29541)

Released/updated on: 2014-11-18
Geographic coverage: Africa, Tanzania
Time period: 1994-01-01--2012-12-31

The TAZAMA Health and Demographic Surveillance System (HDSS) study site is located in the Kisesa and Bukandwe rural electoral wards in the Magu district of the Mwanza Region in Northern Tanzania. The two wards are comprised of six villages. There is one health center and five dispensaries (3 public and 2 private) in the study area. The two wards have eleven government primary schools (at least one in each village) and two secondary schools. Both Mwanza city and Magu town are accessible to residents; buses run along the main road and take about an hour and a half to get to Mwanza. Most of the residents are subsistence farmers; a lot of surplus agricultural produce is traded in Mwanza, which is Tanzania's second city. In the year 2012, the research study covered a population of about 30,000 people who live in the Kisesa and Bukandwe wards. The majority of the residents (about ninety five per cent) belong to the Sukuma ethnic group.

The DSS collects information on births and deaths and movements in and out of the households. It helps researchers to understand the population dynamics in the study area including fertility, mortality and migration patterns. It provides information on the structure of families that live together. The DSS study is also used to identify people who are eligible to participate in the serological surveys (the right age group, and continuously resident rather than just visiting). It provides the data for calculating the denominators for demographic rates.

The objectives of this study are as follows: (1) to improve understanding of the dynamics of the HIV epidemic; (2) to assess the demographic, social and economic impacts of the HIV/AIDS epidemic; (3) to evaluate the effects of national prevention, treatment and care interventions as implemented in Kisesa Ward; (4) to measure child and adult mortality and fertility in the general population and by HIV status; (5) to asses the leading causes of death through verbal autopsy; (6) to assess changes in the family structure due to HIV epidemic; and (7) to provide reliable data for district health planning.

Time period: 1850-01-01--1850-12-31, 1860-01-01--1860-12-31, 1870-01-01--1870-12-31, 1880-01-01--1880-12-31
This component of the Philadelphia Social History Project examines the demographic composition of city grid squares using census data from years 1850, 1860, 1870, and 1880. The collection consists of two types of data files: (1) grid tallies, and (2) grid dictionaries. The grid tally files consist of counts of individuals living in PSHP grid squares, with totals broken down by race/ethnicity, sex, and age. The grid dictionary files link lines in the census manuscripts to PSHP grid squares, allowing users to follow the movements of census-takers as they moved house-to-house on foot, adding individuals to the printed census manuscript forms. The "grid" network consists of a set of vertical and horizontal lines drawn at fixed intervals across a city map, forming the foundation for the spatial organization of the data. The grid dictionary files show when census-takers crossed from one grid square to another; each row in the grid dictionary describes a set of rows that are in a specific grid square by listing the starting page/line and the ending page/line.

County-Specific Net Migration by Five-Year Age Groups, Hispanic Origin, Race and Sex: 2000-2010 (ICPSR 34638)

Released/updated on: 2013-09-05
Geographic coverage: United States
Time period: 2000-01-01--2010-12-31

These data include county-level, net migration estimates by five-year age cohorts and sex, and by race and Hispanic origin, for the intercensal period from 2000 to 2010. The estimates were prepared using a vital statistics version of the forward cohort residual method. These estimates (and the net migration rates derivable from them) extend the set of decennial estimates of net migration that have been produced following each decennial census beginning with 1960 (net migration for the 1950s: Bowles and Tarver, 1965; 1960s: Bowles, Beale and Lee, 1975; 1970s: White, Mueser and Tierney, 1987; 1980s: Fuguitt, Beale, and Voss 2010; and 1990s: Voss, McNiven, Hammer, Johnson and Fuguitt, 2004).

Historical Demographic Data of Southeastern Europe: Orasac, 1824-1975 (ICPSR 32404)

Released/updated on: 2013-05-29
Geographic coverage: Orasac, Europe, Serbia, Global
Time period: 1824-01-01--1975-12-31

The data in the Historical Demographic Data of Southeastern Europe series derive primarily from the ethnographic and archival research of Joel M. Halpern, Professor Emeritus of Anthropology at the University of Massachusetts at Amherst, in southeastern Europe from 1953 to 2006. The series is comprised of historical demographic data from several towns and villages in the countries of Bosnia, Croatia, Macedonia, Montenegro, Serbia, and Slovenia, all of which are former constituent republics of the Socialist Federal Republic of Yugoslavia. The data provide insight into the shift from agricultural to industrial production, as well as the more general processes of urbanization occurring in the last days of the Yugoslav state. With an expansive timeframe ranging from 1818 to 2006, the series also contains a wide cross-section of demographic data types. These include, but are not limited to, population censuses, tax records, agricultural and landholding data, birth records, death records, marriage and engagement records, and migration information.

This component of the series focuses exclusively on the Serbian village of Orasac and is composed of 64 datasets. These data record a variety of demographic and economic information between the years of 1824 and 1975. General population information at the individual level is available in official census records from 1863, 1884, 1948, 1953, and 1961, and from population register records for the years of 1928, 1966, and 1975. Census data at the household level is also available for the years of 1863, 1928, 1948, 1953, and 1961. These data are followed by detailed records of engagement and marriage. Many of these data were obtained through the courtesy of village and county officials. Priest book records from 1851 through 1966, as well as death records from 1863 to 1976 and tombstone records from 1975, are also available. Information regarding migrants and emigrants was obtained from the village council for the years of 1946 through 1975. Lastly, the data provide economic and financial information, including records of individual landholdings (for the years of 1863, 1952, 1966, and 1975), records of government taxation at the individual or household level (for 1813 through 1840, as well as for 1952), and livestock censuses (at both the individual and household level for the years of 1824 and 1825, and only at the individual level for the years of 1833 and 1834).

Politics and the Migrant Poor in Mexico City, 1970-1972 (ICPSR 33281)

Released/updated on: 2012-05-02
Geographic coverage: Mexico, Global, Mexico City
Time period: 1970-01-01--1972-12-31
Politics and the Migrant Poor in Mexico City is a comparative study of male migrants and their city-born neighbors living in six relatively small, predominately low-income communities on the periphery of Mexico City. Based on 14 months of fieldwork in these communities during 1970, 1971, and 1972, this study dealt with a relatively small group of people in a limited number of localities at a particular point in time. The research addressed several broad theoretical and empirical problems such as the most important incentives and disincentives for political involvement, the effect a large group of people entering the political arena has on the functioning of the political system, how the individual citizen -- and especially the disadvantaged citizen -- can manipulate the political system to satisfy their needs, the process by which individuals form images of politics and the political system, the process by which individuals assume a role of participation or non-participation in political activity, what occurs at the "grass roots" of a nation's political system, and how political activity at that level affects system outputs. This study attempted to place the low-income migrant in a social and political context, and focused on the nature and frequency of interactions between the research communities and external actors, especially political and government officials. Demographic variables include age, race, socio-economic status, marital status, dwelling unit type, and religious preference.

Current Population Survey, August 2008: Immigration/Emigration Supplement (ICPSR 31201)

Released/updated on: 2011-10-06
Geographic coverage: United States
Time period: 2008-08-01--2008-08-31

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of immigration and emigration, which was administered as a supplement to the August 2008 CPS questionnaire.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

The August 2008 supplement questions were asked of all household members interviewed in the basic CPS. The supplemental questions collected information on contemporary migration patterns, such as multiple years of entry to and emigration from the United States, time spent living outside the United States, and money sent and received from family and friends living outside the United States.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

Population Registers of Sart, Belgium, 1811-1900 (ICPSR 32461)

Released/updated on: 2011-09-30
Geographic coverage: Belgium, Sart, Global
Time period: 1811-01-01--1900-12-31
The population registers of Sart are part of the Historical Database of the Liège Region (HDLR), which was collected with funding from the University of Liège and the National Institute on Aging (NIA). HDLR is a collection of data describing the characteristics and vital events of individuals from a sample of municipalities in Eastern Belgium spanning the period from 1806 through 1900. It consists of nineteenth century and early twentieth century microdata, which means that it provides information on individuals and the households they belonged to. Because the focus of the National Institute on Aging funded project was on the dynamic of life course transitions, particular attention was given to sources with a longitudinal dimension, showing not a static cross-section but a span of time. The Belgian population registers are exceptionally good sources for longitudinal analysis. Since these registers record dates of in- and out-migration, we are able to reconstruct the population at risk at every point in time. In addition, population registers give us information about household composition as it changed over time. Since migration is recorded in the population registers, a much wider range of analyses are possible. They allow us to reconstruct the biographies of everyone living in these municipalities during most of the nineteenth century. We know not only when they were born, married, and died, but also the lives of their parents, siblings, and children. In other words, it is possible to trace the individuals through time.

Time period: 2005-08-01--2006-11-30

The Displaced New Orleans Residents Pilot Study was designed to examine the current location, well-being, and plans of people who lived in the city of New Orleans when Hurricane Katrina struck on August 29, 2005. The study is based on a representative sample of pre-Katrina dwellings in New Orleans. Fieldwork focused on tracking respondents wherever they currently resided, including back to New Orleans. Respondents were administered a short paper-and-pencil interview by mail, by telephone, or in person. The pilot study was fielded in the fall of 2006, approximately one year after Hurricane Katrina. The goal of DNORPS was to assess the feasibility of the study design and thereby to lay the groundwork for launching a major longitudinal study of displaced New Orleans residents.

ICPSR only holds the public data for the pilot study. The main study (DNORS) was carried out 2009-2010. These data are not yet publicly available, but for more information, visit the RAND Corporation website.
