Over half of public school buildings across the country fail to provide adequate conditions for students to learn and school staff to work. Prior research has established an evidence base of associations between high-quality school building facilities and student, staff, school, and community health and education outcomes. Recognizing this research and the need for facility improvements, Maryland has approved the 21st Century School Buildings Program, which is paid for by Baltimore City Public Schools (City Schools), the State of Maryland, and the City of Baltimore. The program will invest close to $1 billion to renovate or replace over two dozen school buildings. City Schools, with support from the Fund for Educational Excellence, selected the RAND Corporation to study the impact of new school buildings on student, staff, school, and community outcomes.

The goal of this first phase was to collect data prior to the start of the Baltimore 21st Century Building Program and conduct initial exploratory analyses of data from treatment schools (i.e., schools slated for renovation or rebuilding) and comparison schools (i.e., schools with similar student and school characteristics but not slated for renovation or rebuilding). The data compiled here are audits of the street segments immediately surrounding those target schools. These observations from Spring 2016 were collected in an effort to document the conditions and features of the neighborhoods prior to school building renovations.

This data collection describes baseline neighborhood characteristics prior to the 21st Century Buildings School Program. For more information about the Baltimore City Schools and the 21st Century School Building Program, please visit the 21st Century Schools website.

The American Housing Survey (AHS) is a longitudinal survey sponsored by United States Department of Housing and Urban Development (HUD) and conducted by the U.S. Census Bureau (Census). It was first conducted annually between 1973 and 1981 and then biennially from 1983 onward. The purpose of the survey is to provide current and continuous series of data on selected housing and demographic characteristics. The AHS collects data on occupied and vacant housing units and the survey is conducted biennially between May and September of odd-numbered years. HUD and Census make the survey data available for public use.

To better understand the impact of arts and culture on the United States housing choice, the National Endowment of the Art's Office of Research and Analysis (ORA) worked with HUD and the Census to ask a series of questions in the 2015 AHS. The questions, which form the Arts and Cultural Events Module as a supplement to the core data, were designed to better understand the role of arts and culture in United States households' neighborhood choice, their satisfaction with the arts and cultural activities available in their neighborhood and their perception of the impact of arts and culture on neighborhood economic and community development. For additional information related to the core AHS data, please see ICPSR 36753, American Housing Survey (AHS) - Table Creator.

Arts-related variables in the dataset include the importance of living near arts and cultural events, the impact arts and cultural events had on the neighborhood and economy, opportunities for greater interactions, and the encouragement of other people or cultures.

The California Families Project (CFP) is an ongoing longitudinal study of Mexican origin families in Northern California. This study uses community, school, family, and individual characteristics to examine developmental pathways that increase risk for and resilience to drug use in Mexican-origin youth. This study also examines the impact that economic disadvantage and cultural traditions have in Mexican-origin youth. The CFP includes a community-based sample of 674 families and children of Mexican origin living in Northern California, and includes annual assessments of parents and children. Participants with Mexican surnames were drawn at random from school rosters of students during the 2006-2007 and 2007-2008 school year. Data collection included multi-method assessments of a broad range of psychological, familial, scholastic, cultural, and neighborhood factors. Initiation of the research at age 10 was designed to assess the focal children before the onset of Alcohol, Tobacco, and Other Drug (ATOD) use, thus enabling the evaluation of how hypothesized risk and resilience mechanisms operate to exacerbate early onset during adolescence or help prevent its occurrence. This study includes a diversity of families that represent a wide range of incomes, education, family history, and family structures, including two-parent and single-parent families.

The accompanying data file consists of 674 family cases with each case representing a focal child and at least one parent (Two-parent: n=549, 82 percent; Single-parent: n=125, 18 percent). Of the 3,139 total variables, 839 pertain to the focal child, 1,376 correspond to the mother, and 908 items pertain to the father.

Please note: While the California Families Project is a longitudinal study, only the baseline data are currently available in this data collection.

The Chicago Community Adult Health Study (CCAHS) consists of four interrelated components that were conducted simultaneously: (1) a survey of adult health on a probability sample of 3,105 Chicago adults, including direct physical measurements of their blood pressure and heart rate and of height, weight, waist and hip circumference, and leg length; (2) a biomedical supplement which collected blood and/or saliva samples on a subset of 661 survey respondents; (3) a community survey in which individuals described aspects of the social environment of all survey respondents' neighborhoods; and (4) a systematic social observation (SSO) of the blocks in which potential survey respondents resided, including a lost letter drop (Milgram et al. 1965) as an unobtrusive measure of neighborhood social capital/sense of responsibility to help others. The latter two extend a community survey and SSO of neighborhoods carried out by the Project on Human Development in Chicago Neighborhoods (PHDCN) in 1995. The adult health survey and the community survey were conducted jointly through face-to-face interviews with a stratified, multistage probability sample of 3,105 individuals aged 18 and over and living in the city of Chicago, with a response rate of 72 percent that is about the highest currently attainable in large urban areas. In addition, blood pressure, heart rate, and physical measurements (of height, weight, waist and hips, and leg length) were collected during the survey interview, and blood and saliva samples from 661 respondents or 60 percent of those doing the survey in the 80 "focal" neighborhood clusters (NCs). SSOs were conducted on 1,663 of the 1,672 city blocks on which each respondent lived. The CCAHS is the largest of five projects under the NIH-funded Michigan Interdisciplinary Center on Social Inequalities, Mind and Body Mind (#P50HD38986), one of five Mind-Body Centers funded by the National Institutes of Health in late 1999. This study will advance the understanding of socioeconomic and racial/ethnic disparities in health, a major priority of the Public Health Service and the National Institutes of Health.

The PI-supplied summary mentions that the study is comprised of four components. However, for the purposes of this data release there are three distinct datasets. Demographic variables include age, birth year, race, ethnicity, number of children in the household, number of children living elsewhere, number of times the respondent has been married, and relationship status, religious preference, and sex.

The Chitwan Valley Family Study (CVFS) is a comprehensive family panel study of individuals, households, and communities in the Chitwan Valley of Nepal. The study was initially designed to investigate the influence of changing community and household contexts on population outcomes such as marital and childbearing processes. Over time, the goals of the study expanded to investigate family dynamics, intergenerational influences, child health, migration, labor force participation, attitudes and beliefs, mental health, agricultural production, environmental change, and many other topics. The data include full life histories for more than 10,000 individuals, tracking and interviews with all migrants, continuous measurement of community change, over 25 years of demographic event registry, and many other data collections. For additional information regarding the Chitwan Valley Family Study, please visit the Chitwan Valley Family Study Website. A Data Guide for this study is available as a web page and for download.

The current study sought to expand the current understanding of the psychometric characteristics of the collective efficacy scale at the individual level and the role of collective efficacy in promoting safe, healthy community conditions. A team of interviewers consisting of residents of the targeted neighborhoods were selected and trained to administer the field surveys (NIJ Neighborhoods Resident Survey Data, 108 variables, n=649). In order to ensure accuracy of the responses, the field supervisor conducted telephone validation for approximately ten to fifteen percent of the surveys. In addition to resident surveys, trained research staff conducted systematic social observations (SSOs) of street segments in selected neighborhoods noting physical and social indictors.

This study sampled Black households within the city of Detroit in the spring and summer of 1968 and interviewed the head of household or spouse of the head of household. The study examined contact between Blacks and Whites and the views of Blacks regarding Black militancy, community control, Black consciousness, and anti-White sentiments. Questions included in the interview determined the number and type of contacts respondents had with whites, the respondents' attitudes toward child-rearing, and political activities at neighborhood churches. Perceptions of various local problems were probed, including the effects of the 1967 Detroit riots. Respondents were also asked about the best means for Blacks to gain their rights and reasons for the high unemployment rate in Detroit. Other topics covered respondents' experiences with and awareness of racial discrimination in the areas of housing, local police activities, business relations, and job opportunities. Background information on respondents includes age, sex, race, marital status, religious affiliation, and church activities. The respondent's residence up to age 10, length of residence in Detroit and in their current neighborhood, and the racial composition of the neighborhood were ascertained. Respondent's educational level, the racial composition of schools the respondent attended, and respondent's service in the military were also recorded. Other demographic information was gathered regarding the number of adults and children living in the household, as well as the number of rooms in the house, family income, and income sources. The respondent was also asked about the educational levels and occupations of other family members.

This study examines the attitudes of White adults living in the greater Detroit Metropolitan area toward neighbors and Blacks. In particular, the study measured respondents' reactions to Blacks moving into their neighborhood, Black children playing with their child, and Blacks working at the same job. The study also assessed the current neighborhood situation with respect to the dominant socioeconomic patterns. Demographic information includes respondent's age, gender, marital status, employment status, family income, religious preference, and occupation.

The 2001 Detroit Area Study (DAS) is a survey of over 4,300 adults in metro Detroit and addresses their perceptions, expectations, satisfaction, and behaviors associated with community living. The 2001 DAS, conducted in the spring and summer 2001, consisted of two parts. Initially, face-to-face interviews were conducted with a probability sample of 315 adult respondents (18 years of age and older) living in the tri-county area of Wayne, Oakland, and Macomb Counties. Subsequently, a questionnaire was mailed to a sample of adults throughout the seven counties; 4,077 were returned. Response rates were 59.8 percent for the face-to-face sample and 56.7 percent for the mail sample. In addition to survey responses, DAS 2001 compiled contextual information about the minor civil divisions (MCDs) or communities and environments associated with each respondent. Contextual information includes housing and demographic characteristics, land use characteristics, and other characteristics of the communities where respondents live (growth rates, employment, school information). Questions on the survey asked about residential history; public services and transportation; government and taxes; schools; police; parks, recreation and where kids play; shopping and other community issues; community participation and involvement; neighborhood and neighboring; housing and prospective mobility; safety; employment and journey to work; health and health care facilities; other Detroit and regional issues; demographics; and observations. The 2001 DAS presents a unique opportunity to explore and record changes over time by measuring people's opinions and behaviors and the conditions in their communities. The 2001 DAS is different from earlier DAS surveys in several ways. First, the study has been expanded from three to seven counties in southeast Michigan, often referred to as the metro Detroit area. That is, the study contacted residents in Livingston, Macomb, Monroe, Oakland, St. Clair, Wayne, and Washtenaw counties and in the city of Detroit. Second, the number of people contacted is greatly increased using a combination of face-to-face interviews and questionnaires sent by mail. Over 4,000 households in the region were contacted. Third, the questionnaires were designed in consultation with stakeholder groups representing government, industry, and nonprofit organizations in the region. Finally, indicators associated with the sampled households are being compiled and analyzed (along with the survey responses) using statistical and spatial analytic techniques including Geographic Information Systems (GIS).

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. The 13th survey wave, collected between June 2, 2021 and July 9, 2021, invited 2,713 previously-enrolled panelists to participate in a self-administered or interviewer-administered survey. Topics include experience with COVID-19; COVID-19 vaccine receipt, attitudes and trust; employment and economic precarity; neighborhood satisfaction; neighborhood blight; housing repair; as well as crime, safety and policing.

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. Between January 13, 2025 and March 3, 2025, 3,112 previously enrolled panelists were invited to participate in a self-administered online or interviewer-administered telephone survey.

Topics included: household composition; housing status; perceptions of neighborhood; political trust; challenges; homeownership; homeowner's insurance; stormwater management; flooding; mental health; employment.

The Detroit Neighborhood Health Study (DNHS) is a prospective, representative longitudinal cohort study of predominantly African American adults living in Detroit, Michigan. The main purpose of the study was to determine the predictive effects of ecological stressors, such as income distribution and residential segregation, on the development of post-traumatic stress disorder (PTSD), substance use, and other psychological and behavioral outcomes. An additional purpose was to study the interrelationships between ecological stressors, exposure to potentially traumatic events (PTEs), PTSD, substance use, and immune function. The study team hypothesized that exposure to ecological stressors would influence the risk of PTE exposure, PTSD, substance use, other psychological outcomes, and the relationships between these factors.

The current collection includes data from all 5 waves of the study. Cohort participants were initially recruited in 2008 with a dual-frame probability design, using telephone numbers obtained from the U.S. Postal Service Delivery Sequence Files as well as a listed-assisted random-digit-dial frame. Individuals without listed landlines or telephones and individuals with only a cell phone listed were invited to participate through a postal mail effort. Participants completed a 40 minute, structured telephone interview annually between 2008-2012 to assess perceptions of participants' neighborhoods, mental and physical health status, social support, exposure to traumatic events, and alcohol and tobacco use. In addition, the study team completed a structured assessment of Detroit's 54 neighborhoods in order to describe the characteristics of respondents' neighborhoods. The assessment included information about the quality of housing exteriors; presence of graffiti, abandoned cars, alcohol and tobacco advertisements, and security warning signs; presence of vacant buildings; and street and traffic noise levels.

All survey participants were offered the opportunity to provide a blood specimen (venipuncture, blood spot, or saliva) for immune and inflammatory marker testing as well as genetic testing of DNA. Participants received an additional $25USD if they elected to give a sample. Informed consent was obtained at the beginning of each interview and again at specimen collection. However, these specimens are not included as part of this data collection.

Genotypic data from DNHS are available on the NIH database of Genotypes and Phenotypes (dbGaP).

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.

The East Asian Social Survey (EASS) is a biennial social survey project that serves as a cross-national network of the following four General Social Survey type surveys in East Asia: the Chinese General Social Survey (CGSS), the Japanese General Social Survey (JGSS), the Korean General Social Survey (KGSS), and the Taiwan Social Change Survey (TSCS), and comparatively examines diverse aspects of social life in these regions. Since its 1st module survey in 2006, EASS produces and disseminates its module survey datasets and this is the harmonized data for the 4th module survey, called 'Network Social Capital in East Asia,' which was carried out in 2012 in the four countries.

Survey information in this module focuses on social networks and participation and attitudes toward various social organizations and events. Respondents were asked about common social interactions, family structures and relationships, their neighborhood environments, social support systems, and their trust toward a range of community members and institutions. Additionally, respondents were asked for their opinions on political issues, and about their participation and experience with voting in recent elections.

Demographic and other background information includes age, sex, marital status, religion, years of education completed, employment status, income, and household size and composition.

The overall goal of this research project was to examine the impact that risk assessment has on the sentencing of racial minority youth and youth from disadvantaged neighborhoods. One of the main goals of correctional risk assessment is to reduce disparate outcomes for certain groups of youth in the juvenile justice system (e.g. Black youth). In practice, risk assessment is used with this goal in mind. However, there is very little research which shows whether or not risk assessment actually has its intended effects on sentencing. Therefore, this study set out to examine whether or not risk assessment reduces the sentencing gap seen in most research for minority youth and youth from disadvantaged neighborhoods. In addition, several other important research topics were explored to understand the role that race and socioeconomic disadvantage play in the juvenile justice system. These research topics included: (1) variation in the predictive validity of risk assessment across race, (2) variation in the predictive validity of risk assessment across neighborhood disadvantage, and (3) the moderating effects of race/gender and court dispositions on the predictive validity of risk assessment.

To achieve the research goals in this study, data was collected from a large juvenile court in a Midwestern County. Information from 4,383 youth that came into contact with the court between January 2010 and December 2016 were included in the study. Data was collected that related to youth demographics, neighborhood characteristics in which youth lived, risk assessments data measured by the Ohio Youth Assessment System (OYAS), treatment programming received, court dispositions/sentencing, and recidivism.

This study is a restricted data file of data from the L.A.FANS Neighborhood Observation Study, an in-person observational by trained L.A.FANS interviewers of the census blocks on which L.A.FANS respondents lived during L.A.FANS Wave 1. Interviewers were trained to walk each block face and record social and physical observations on precoded check sheets. Each block face was observed by several different interviewers working independently at different times of the day and week. These data are designed to be used with L.A.FANS Wave-1 survey interview data restricted versions 2.5 or 3 to provide data on the census block and census tract in which individual respondents lived.

Users who apply for these restricted data must also be approved for using restricted version 2.5 or 3. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis.

The study is described in detail in the L.A.FANS Neighborhood Observations Codebook.

The Los Angeles Family and Neighborhood Survey (L.A.FANS) is a two-wave study of adults and children in Los Angeles County and of the neighborhoods in which they live. The first wave (L.A.FANS-1), which was fielded between April 2000 and January 2002, interviewed adults and children living in 3,085 households in a stratified probability sample of 65 neighborhoods throughout Los Angeles County. The samples of neighborhoods and individuals were representative of neighborhoods and residents of Los Angeles County. Poorer neighborhoods and households with children were oversampled. In Wave 2 of L.A.FANS (L.A.FANS-2), Wave 1 respondents living in Los Angeles County were reinterviewed and updated information was collected on Wave 1 respondents who had moved away from Los Angeles County. A sample of individuals who moved into each sampled neighborhood between Waves 1 and 2 was also interviewed, for a total of 2,319 adults and 1,382 children (ages less than 18 years). Additional information on the project is available at the RAND website.

This study includes a restricted data file for Wave 1 of the L.A.FANS data. To compare L.A.FANS restricted data, version 1 with other restricted data versions, see the table on the series page for the L.A.FANS data here. Data in this study are designed for use with the public use data files for L.A.FANS, Wave 1 (study 1). This file adds only a few variables to the L.A.FANS, Wave 1 public use files. Specifically, it adds a "pseudo-tract ID" which is a number from 1 to 65, randomly assigned to each census tract (neighborhood) in the study. It is not possible to link pseudo-tract IDs in any way to real tract IDs or other neighborhood characteristics. However, pseudo-tract IDs permit users to conduct analyses which take into account the clustered sample design in which neighborhoods (tracts) were selected first and then individuals were sampled within neighborhoods. Pseudo-tract IDs do so because they identify which respondents live in the same neighborhood. It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the L.A.FANS Wave 1 Users Guide and Codebook. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 1 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis.

The Los Angeles Family and Neighborhood Survey (L.A.FANS) is a two-wave study of adults and children in Los Angeles County and of the neighborhoods in which they live. The first wave (L.A.FANS-1), which was fielded between April 2000 and January 2002, interviewed adults and children living in 3,085 households in a stratified probability sample of 65 neighborhoods throughout Los Angeles County. The samples of neighborhoods and individuals were representative of neighborhoods and residents of Los Angeles County. Poorer neighborhoods and households with children were oversampled. In Wave 2 of L.A.FANS (L.A.FANS-2), Wave 1 respondents living in Los Angeles County were reinterviewed and updated information was collected on Wave 1 respondents who had moved away from Los Angeles County. A sample of individuals who moved into each sampled neighborhood between Waves 1 and 2 was also interviewed, for a total of 2,319 adults and 1,382 children (ages less than 18 years). Additional information on the project is available at the RAND website.

Data in this study are designed for use with the public use data files for L.A.FANS, Wave 2 (study 2). This file adds only a few variables to the L.A.FANS, Wave 2 public use files. Specifically, it adds a "pseudo-tract ID" which is a number from 1 to 65, randomly assigned to each census tract (neighborhood) in the study. It is not possible to link pseudo-tract IDs in any way to real tract IDs or other neighborhood characteristics. However, pseudo-tract IDs permit users to conduct analyses which take into account the clustered sample design in which neighborhoods (tracts) were selected first and then individuals were sampled within neighborhoods. Pseudo-tract IDs do so because they identify which respondents live in the same neighborhood. It also includes certain variables, thought to be sensitive, which are not available in the public use data. These variables are identified in the L.A.FANS Wave 2 Users Guide and Codebook. Finally, some distance variables and individual characteristics which are treated in the public use data to make it harder to identify individuals are provided in an untreated form in the Version 1 restricted data file. Please note that L.A. FANS restricted data may only be accessed within the ICPSR Virtual Data Enclave (VDE) and must be merged with the L.A. FANS public data prior to beginning any analysis.

A Users' Guide which explains the design and how to use the samples are available for Wave 2 at the RAND website.
