Afrobarometer Round 6: The Quality of Democracy and Governance in Zambia, 2014 (ICPSR 36740)

Released/updated on: 2018-02-06

Geographic coverage: Africa, Zambia, Sub-Saharan Africa

The Afrobarometer is a comparative series of public attitude surveys that collects and disseminates data regarding Africans' views on democracy, governance, the economy, civil society, and related issues. The data are collected from nationally representative samples in face-to-face interviews in the language of the respondent's choice. Standard topics for the Afrobarometer include attitudes toward and evaluations of democracy, governance and economic conditions, political participation, and national identity. In addition, round 6 surveys included special modules on taxation; tolerance; crime, conflict and insecurity; political corruption; interregional relations; perceptions of China; use of technology; and social service delivery.

This particular data collection was concerned with the attitudes and opinions of the citizens of Zambia, and also includes a number of "country-specific questions" designed specifically for respondents of the Zambia survey. These "country specific questions" solicited respondents' opinions on topics such as attitudes toward Common Market for Eastern and Southern Africa (COMESA); expectations of Members of Parliament in their constituency/term; Parliament or Constituency decisions regarding Constituency Development Funds (CDFs); primary source of news regarding deliberations in the National Assembly; domestic and institutional violence; challenges in land acquisition; rights in the sale of land; and attitudes regarding street commerce.

The surveys also collect a large set of socio-demographic indicators such as age, gender, education level, poverty level, language and ethnicity, and religious affiliation, as well as political party affiliation. Afrobarometer Round 6 surveys were implemented in 36 countries.

Released/updated on: 2009-08-14

Geographic coverage: China (Peoples Republic)

The purpose of this project was to measure and estimate the distribution of personal income and related economic factors in both rural and urban areas of the People's Republic of China. The principal investigators based their definition of income on cash payments and on a broad range of additional components. Data were collected through a series of questionnaire-based interviews conducted in rural and urban areas at the end of 2002. There are ten separate datasets. The first four datasets were derived from the urban questionnaire. The first contains data about individuals living in urban areas. The second contains data about urban households. The third contains individual-level economic variables copied from the initial urban interview form. The fourth contains household-level economic variables copied from the initial urban interview form. The fifth dataset contains village-level data, which was obtained by interviewing village leaders. The sixth contains data about individuals living in rural areas. The seventh contains data about rural households, as well as most of the data from a social network questionnaire which was presented to rural households. The eighth contains the rest of the data from the social network questionnaire and is specifically about the activities of rural school-age children. The ninth dataset contains data about individuals who have migrated from rural to urban areas, and the tenth dataset contains data about rural-urban migrant households. Dataset 1 contains 151 variables and 20,632 cases (individual urban household members). Dataset 2 contains 88 variables and 6,835 cases (urban households). Dataset 3 contains 44 variables and 27,818 cases, at least 6,835 of which are empty cases used to separate households in the file. The remaining cases from dataset 3 match those in dataset 1. Dataset 4 contains 212 variables and 6,835 cases, which match those in dataset 2. Dataset 5 contains 259 variables and 961 cases (villages). Dataset 6 contains 84 variables and 37,969 cases (individual rural household members). Dataset 7 contains 449 variables and 9,200 cases (rural households). Dataset 8 contains 38 variables and 8,121 cases (individual school-age children). Dataset 9 contains 76 variables and 5,327 cases (individual rural-urban migrant household members). Dataset 10 contains 129 variables and 2,000 cases (rural-urban migrant households).

The Chinese Household Income Project collected data in 1988, 1995, 2002, and 2007. ICPSR holds data from the first three collections, and information about these can be found on the series description page. Data collected in 2007 are available through the China Institute for Income Distribution.

Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil (ICPSR 25322)

Released/updated on: 2009-12-16

Geographic coverage: Rondonia, Brazil, Global

Time period: 1996-01-01--2005-01-01

This study, which updates DIFFUSION OF SUSTAINABLE AGRICULTURE IN THE AMAZON [BRAZIL]: A PANEL DATABASE, 1996-2000 (ICPSR 3948), examines household land use and economic welfare in the Amazon basin through the collection of a third round of panel data with improved spatial referencing and a new system for tracking households and individuals. The study area is typical of the arc of deforestation across the southern Brazilian Amazon. Data from this study were used to model the relationship between deforestation and household well-being, thereby gaining insight on welfare outcomes that also have implications for conservation policies. Face-to-face interviews were conducted with the residents of the Ouro Preto do Oeste region of the Brazilian state of Rondonia. Demographic questions focused on: education, age, household size, migration and place of birth of the residents. Other questions focused on the ownership of the lots, years of residency on the lots, household income sources, household wealth and assets, as well as household cost of living.

Explaining Developmental Crime Trajectories at Places: A Study of "Crime Waves" and "Crime Drops" at Micro Units of Geography in Seattle, Washington, 1989-2004 (ICPSR 28161)

Released/updated on: 2013-08-05

Geographic coverage: Seattle, United States, Washington

Time period: 1989-01-01--2004-01-01

This study extends a prior National Institute (NIJ) funded study on mirco level places that examined the concentration of crime at places over time. The current study links longitudinal crime data to a series of other databases. The purpose of the study was to examine the possible correlates of variability in crime trends over time. The focus was on how crime distributes across very small units of geography. Specifically, this study investigated the geographic distribution of crime and the specific correlates of crime at the micro level of geography. The study reported on a large empirical study that investigated the "criminology of place." The study linked 16 years of official crime data on street segments (a street block between two intersections) in Seattle, Washington, to a series of datasets examining social and physical characteristics of micro places over time, and examined not only the geography of developmental patterns of crime at place but also the specific factors that are related to different trajectories of crime. The study used two key criminological perspectives, social disorganization theories and opportunity theories, to inform their identification of risk factors in the study and then contrast the impacts of these perspectives in the context of multivariate statistical models.

The Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) study is a population-based survey that aims to examine and characterize a population of older men and women in rural South Africa with respect to health, physical and cognitive function, aging, and well-being, in harmonization with other Health and Retirement Studies.

The baseline survey was conducted among 5,059 men and women aged 40 years or older, who were sampled from within the existing framework of the Agincourt health and socio-demographic surveillance system (AHDSS), in rural Mpumalanga province, South Africa. Survey data were collected on cognitive and physical functioning, social networks, cardiometabolic disease and risk factors, HIV and HIV risk, and economic well-being. The survey also included anthropometric measures and point-of-care blood tests for hemoglobin, glucose and lipids. Dried bloodspots (DBS) were collected at the survey and later tested for HIV, HIV viral load, glucose and CRP. A sub-sample had more extensive laboratory follow-up testing, which will be available in future data releases. A second wave of the survey was administered in 2018 through 2019, and a third wave of the survey was administered in 2021 through 2022.

Demographic information includes age, sex, income, education, marital status, number of children, and employment.

Harvard dataverse hosts an additional restricted-use dataset which compliments this collection, the HAALSI Baseline HIV Biomarker Data; users interested in obtaining these data must request access based on the terms outlined in the data use agreement.

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--1975-01-01

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).

This study is one in a series of election studies conducted since 1969 by Alan Arian and Michal Shamir that investigated voting patterns, public opinion, and political participation in Israel. This study in particular was conducted during May 1973-January 1974, prior to the elections of the 8th Knesset, and carried out in five phases. Respondents were asked to evaluate their general personal situations and that of Israel, and identify their knowledge of politics, interest and involvement in politics, previous participation in a youth movement, access to media (television, radio, and newspaper) pertaining to political affairs, and factors which would influence voting decisions including the October 1973 Yom Kippur War. Views were also elicited from respondents in regard to the Israeli government including the main problems it faces, a time estimate for resolution, and the development of a peace agreement with the Palestinians to end the Arab-Israeli conflict. Respondents were asked to define and evaluate political parties such as an ideal party, Gahal Party, and Alignment Party, and to evaluate other political parties such as the Labor Party and National Religious Party. In addition, respondents were queried about their knowledge of the new Likud Party and Gahal Party and whether each party, if elected, would bring changes to the government and represent a substitute for the Labor Party. Respondents' opinions were sought in regard to Prime Minister Golda Meir, Defense Minister Moshe Dayan, Likud Party Chairman Menachem Begin, and Knesset member Ariel Sharon and other political leaders including the city mayor and several combinations of political coalitions. Respondents also gave their level of satisfaction with the elections and government, and their views on social and economic issues, foreign, security, and peace matters (including occupied territories), the positions of political parties (including the opposition), and attributes of political parties and leaders. The survey queried respondents about both the election's and their own personal ability to influence government policy. Questions covered voting intention and history (personal and paternal), the importance of voting in the election versus supporting a particular party, coverage of elections in the media, perception of leaders, the effects of the election campaign, their views on public polls, and their participation in the election. Respondents also identified the role of the Histadrut as a trade union, whether they were members of this organization or a medical insurance plan, and how they received medical treatment. Post-war surveys asked respondents for their opinions about the political parties and candidates and for whom to vote, the influence of the Yom Kippur War on Israel and factors responsible for the changes, and whether the elections should be held on December 31, 1973, or postponed for a length of time. Demographic questions include gender, age, birthplace and education (personal and paternal), marital status, head of household, occupation, employment status and sector, employer, monthly family income, household characteristics, and left-right political self-placement. In addition, respondents were queried about the year they immigrated to Israel, their observation of religious tradition, and whether and how long the husband belonged to the army during the war. Place and date of the interview have only been included in the December 1973 Survey and January 1974 Survey.

The Justice of Land in a Land of Injustice, 2004 (ICPSR 30102)

Released/updated on: 2011-11-29

Geographic coverage: Africa, South Africa, Global

Time period: 2004-02-11--2004-10-07

The Justice of Land in a Land of Injustice study was conducted in South Africa. This study examined the lingering effects of Apartheid, with a focus on land distribution. Respondents were asked about their media usage, their interest in politics, whether they discussed politics with others, the general economic situation in South Africa, and their family's standard of living. They were then asked about their relationships with other people, including whether they got along with those with differing opinions, viewpoints, and values. Respondents were also asked about property rights. Questions included whether the land rights of the wealthy should be reduced, if community rights were more important than individual rights, if only property owners should be allowed to vote, if people had a right to land they had lived on for a long time despite not owning it, whether people should receive compensation if their land should be taken away for land reform, the possible consequences of taking away land rights, if land should be taken away from certain groups only, or whether all land right claims should be denied. Respondents were queried about civil rights and freedoms. Questions included how important rights such as free speech, the right to protest, and the right to land ownership were to them. They were also asked whether it was acceptable for the police to search houses without permission in order to fight crime and if sometimes it would be necessary to ignore the law to solve problems. Respondents were then asked to list the groups they do and do not identify with, and how they felt about being a member of a group. They were asked to self-categorize into groups and then queried about their interactions and relations with other groups. They were asked how much contact they had with other groups and how many of their "true" friends were members of different groups. Respondents were also asked how well they understood the customs of other groups, if they were uncomfortable being around or sharing the same political party with a group, and if South Africa would be better off if other groups were not present. Next, respondents were asked about Apartheid. Questions included how many Black people were harmed by Apartheid, if large companies both inside and outside of South Africa were to blame for the harm done, and whether these companies should be forced to pay for the harm they caused under Apartheid. Additionally, they were queried about their life under Apartheid compared to their current life, including past experiences such as having to use a pass to move around, and being assaulted by the police. Respondents were also asked about their knowledge of government organizations including the South African Constitutional Court and Parliament, and their satisfaction with these organizations. They were then asked how important certain issues were to them such as drugs, unemployment, and racial reconciliation. Additionally, they were asked about the election of leaders, and whether multi-party elections were effective ways to choose those leaders. Respondents were also asked about the goods they owned and their financial assets. The survey also included several vignettes with scenarios of land disputes, which were read to the respondents. They were then asked their opinions of the possible outcomes of these vignettes. Demographic information included age, year of birth, highest education level completed, language spoken mostly at home, attendance at places of religious worship, religion, employment status, household composition, how long they have lived in their current community, whether that community had a Traditional Leader, ownership of goods, membership in organizations, whether someone close has died of AIDS, has AIDS, or are HIV positive, and province, size, and metropolitan area of residence. Finally, interviewer attributes and observations are included.

Land Use, Agropastoral Production, Family Composition, and Household Economy in Santarem, Para, Brazil, June-August 2003 (ICPSR 34347)

Released/updated on: 2013-04-01

Geographic coverage: Brazil, Global, Santarem

The 2003 Santarem dataset consists of 8 interconnected datasets and 1 linking file. The primary unit of analysis is the rural property or lot. Each lot in the sample contains a minimum of 1 household with a mean of 1.33 households per lot in the final sample. Within households, data were collected on subsets of individuals as well as additional properties used by the households in the study. These 2003 Santarem data come from interviews with farm families in an agricultural zone south of the city of Santarem in the Brazilian state of Para. Santarem is a relatively old settlement within the Brazilian Amazon that has experienced waves of regional settlement in the 1930s, mid-century, and the 1970s. The study region is adjacent to the confluence of the Amazon and Tapajos Rivers and the northern terminus of the BR-163 (the Cuiaba-Santarem Highway). BR-163 links intensive agropastoral production (particularly mechanized soybean farming) in the state of Mato Grosso to Santarem, where the multinational corporation Cargill runs a deepwater port (opened in 2003) for loading soybeans onto oceangoing ships. The opening of this port has accelerated the process of urbanization and led to a transformation from a landscape of small family farming to a landscape of mechanized agriculture (description adapted from VanWey, Leah K., and Kara B. Cebulko, 2007, Journal of Marriage and the Family 69: 1257-1270). The discourse on deforestation has focused on the alarming rates of deforestation in the Amazon Basin to the neglect of the dynamic and reciprocal influences between the human population and the environment. Deforestation is a process mediated by human intervention, from the act of clearing to how such a clearing is used and managed over time. It would be helpful to know whether observable rates of forest removal represent a stage in the developmental cycle of households or represents the simple and direct impact of increasing population in these environments. From the point of view of theory and method, it is necessary to develop new approaches that effectively link demographic process to the interactive relationship of population to specific aspects of an environmental matrix. This project addressed multiple scales, from household dynamics to landscape dynamics and has developed methods by which to scale between them. We hypothesize that as households occupy frontier areas past the first generation, they move from a strategy of managing their land under the constraints of available household labor to a strategy that gives greater recognition of the constraints posed by land quality and of the risks to their farm operation coming from external socioeconomic forces and biophysical constraints. In the first generation, the labor available to a household is determined by the size of the household making the initial trip to the frontier (primarily young couples is common in frontier regions) and later by the fertility of these initial migrants. As these initial migrants age and their children enter adulthood (thereby becoming the second generation), labor supply is determined by the reproductive and land use choices of these children. Given the precipitous decline in female fertility, other factors gain salience in the second generation: the suitability of the land for various uses, the availability of off-farm employment and educational opportunities (both locally and those requiring migration), and macroeconomic factors affecting the economic viability of farming. These decisions then directly determine the entries into and exits from the household. This study investigated five basic questions: (1) Does the changing availability of household labor over the household life cycle affect the trajectory of deforestation and land use change in the same way for later generations of Amazonian farmers as for first generation in-migrants? (2) What are the determinants of changing household labor supply? Specifically, what are the biophysical and socioeconomic determinants of entries into and exits from the household through fertility, migration, and marriage? (3) How are the decisions of households regarding land use and labor allocation constrained by soil quality, access to water supplies, interannual drought events (e.g. El Nino type events), and other resource scarcities? (4) Are there notable differences in land use choices made by landholders who live in an urban area (away from the piece of land owned in the rural area) in contrast to the decisions made by those who live on their rural properties? (5) What are the bases for the precipitous decline in female fertility in these frontier regions, especially the use of sterilization after two pregnancies? Households will be surveyed in the Santarem region, in the Lower Tapajos Basin, Brazilian Amazon to collect detailed demographic, land-use histories, and economic data. The sampling of households for inclusion in the study will be based on a stratified random sample by period of occupation in Santarem, to capture intergenerational processes that preceded the availability of satellite images. Based on the particular combination of methodologies used in this investigation (traditional household surveys, satellite image analysis, and GIS, and the scaling up and down from households to landscape), future environmental changes were projected for the regional landscape under various scenarios of continued settlement, household life cycles, combinations of credit, and changing environmental conditions.

Longitudinal Survey Data of Households in Ouro Preto do Oeste, Rondonia, Brazil, 1996-2009 (ICPSR 34905)

Released/updated on: 2014-07-15

Geographic coverage: Rondonia, Brazil, Global

Time period: 1996-01-01--2009-01-01

This study, which updates Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil (ICPSR 25322), examines household land use and economic welfare of residents living in the highly deforested Amazon basin region of southern Brazil. This release represents the fourth round of data collection which includes primary data from household panel surveys in the core study area, combined with several other sources of data, including cadastral maps matched with satellite imagery to quantify land cover change, spatial data on biophysical factors, markets, and public infrastructure, and secondary data from official sources (such as agricultural census data). Interviews were conducted with respondents residing in the Ouro Preto do Oeste region of the Brazilian state of Rondonia. Survey questions focused on respondent ownership of land lots, years of residency on the lots, property sales, physical characteristics of lots and dwellings, types and quantity of livestock and crops, and use of fertilizers, pesticides, and herbicides. Several questions asked respondents whether they owned various durables, including vehicles, household appliances, tools, and farm equipment. Demographic information includes age of respondent and other household occupants, household size, migration, and education level, as well as information on household income, assets, pensions, and cost of living.

Military Bounty Land Warrants in the United States, 1847-1900 (ICPSR 9514)

Released/updated on: 1992-02-17

Geographic coverage: United States

Time period: 1847-01-01--1900-01-01

Between 1847 and 1855 the Congress of the United States passed four land warrant acts which granted 60 million acres of land to veterans and their heirs. The Pension Bureau determined the eligibility of these individuals and issued military bounty land grants for up to 160 acres. Most of these land warrants were issued before 1860, but the government continued to make grants through the remainder of the 19th century. Because of these Congressional acts approximately one in nine U.S. families received a land warrant for earlier military service. Families usually sold their warrants for cash to third parties who then presented them to the General Land Office as payments for parcels of public land. Variables include the number of acres awarded to the warrant recipient, the conflict in which the veteran served, his wartime military rank, his state of residence, the public land office where the warrant was located, the year the warrant was issued, and the type of military unit in which the veteran served. Information is also provided concerning the ability of the recipient to sign his name, the relationship of the recipient to the original veteran, whether or not the grant had been sold, and, if so, the name of the buyer.

Zillow Transaction and Assessment Database (ZTRAX), United States, 1940-2020 (ICPSR 39652)

Released/updated on: 2026-01-27

Geographic coverage: United States

Time period: 1940-01-01--2020-01-01

The Zillow Transaction and Assessment Database (ZTRAX) is the country's largest collection of real estate data. Zillow makes the data available in the interest of greater transparency in the real estate market. ZTRAX's temporal coverage varies greatly by county. Some counties have digitized records extending back to the early 1990s, whereas other counties have only provided data to the mid-2000s. In Zillow's work analyzing these data to create home value indices, they have found sample sizes are sufficient for most areas going back to April 1996. Zillow sources ZTRAX from a major large third-party provider and supplemented through an internal Zillow initiative called "County Direct." The data coverage gaps inherited through the third-party source are due to county recording procedures, as well as the data collection process of that third party. Changes to the collection process have occurred over time due to mergers and other organizational changes, as well as process improvements. Because of the gaps in coverage, Zillow instituted its County Direct program. This program prioritizes counties on a variety of characteristics and supplements the third-party coverage by collecting data directly from county assessor and recorder's offices. These data include:

More than 400 million detailed public records across 2,750+ U.S. counties;
More than 20 years of deed transfers, mortgages, foreclosures, auctions, property tax delinquencies, and more, for both commercial and residential properties;
Property characteristics, geographic information, and prior valuations for approximately 150 million parcels in 3,100+ counties nationwide.

ZTRAX does not contain:

Zestimates
Rent data (such as rent prices)
Listing data (such as time on market)
User search data

The ZTrax data will be updated approximately twice per year. These datasets are very large. Researchers wishing to use the data should plan to download subsets containing only the geographic areas in which they are specifically interested. ICPSR suggests going to the following resources for examples of code for utilizing the ZTRAX data. Please note that code will need to be updated based on local pathnames, files included, and the like:
