HUD: Participating Jurisdictions Survey Data (ICPSR 219406)

Released/updated on: 2026-04-17
Text source: https://www.huduser.gov/portal/publications/hsgfin/addi.html
In recognition of the fact that a lack of savings is the most significant barrier to homeownership for most low-income families1, Congress passed the American Dream Downpayment Act of 2003, which established the American Dream Downpayment Initiative (ADDI). The ADDI program was designed to provide assistance with downpayments, closing costs, and, if necessary, rehabilitation work done in conjunction with a home purchase. This formula-based program disburses assistance through a network of Participating Jurisdictions (PJs) in all 50 states and affords them significant flexibility in designing homebuyer programs to meet the needs of their communities. Established as part of the HOME program,2 ADDI is a prime example of direct federal assistance to promote low-income homeownership. In recent years there have been growing concerns that many new low-income homeowners have had difficulty maintaining homeownership.3 To address these concerns in the context of the ADDI program, the Fiscal Year 2006 U.S. Senate Report on the Transportation, Treasury and HUD Appropriations Bill directed the U.S. Department of Housing and Urban Development (HUD) to report on the foreclosure and delinquency rate of households who received downpayment assistance through ADDI.4 This report has been developed in response to this congressional mandate. Due to the limited program history of ADDI, and since HOME-assisted homebuyers are quite similar to those assisted by the ADDI, this study jointly estimates annual foreclosure and delinquency rates for both HOME- and ADDI-assisted borrowers who purchased homes during the period from 2001 through 2005.5 While all HOME/ADDI-assisted borrowers were included in the analysis, in order to have the results be representative of the ADDI program, the sample of PJs was limited to those that were eligible for an allocation of ADDI funds in 2004, the year in which the largest number of PJs were eligible. The primary objective of the study, which addresses the congressional inquiry, is to provide an estimate of the foreclosure and delinquency rates among HOME/ADDI-assisted homebuyers. HUD was also interested in an analysis of the reasons behind these outcomes. Thus, a secondary objective of this study is to analyze the factors associated with variations in delinquency and default rates.
1 See, for example, U. S. Department of Housing and Urban Development, Barriers to Minority Homeownership, July 17, 2002, and Herbert et al., Homeownership Gaps Among Low-Income and Minority Borrowers and Neighborhoods, U.S. Department of Housing and Urban Development, March 2005. 2 Created under Title II of the National Affordable Housing Act of 1990, the HOME program is designed to provide affordable housing to low-income households, expand the capacity of nonprofit housing providers, and strengthen the ability of state and local governments to develop and implement affordable housing strate-gies tailored to local needs and priorities. 3 See, for example, Dean Baker, "Who's Dreaming?: Homeownership Among Low-Income Families," Center for Eco-nomic and Policy Research, Washington, DC, January 2005. 4 Throughout our discussion the terms "default" and "foreclosure" are used to refer to the same outcome where homeowners lose their home in foreclosure. 5 Foreclosure and delinquency rates for 2000 are not included here as the data was not consistent enough to produce valid estimations. This report is based in part on surveys of participating jurisdictions.***Microdata: YesLevel of Analysis: Group - Loan Types; Individual - LoansVariables Present: Yes - Separate DocumentFile Layout: .sasCodebook: YesMethods: YesWeights (with appropriate documentation): Allegedly weighted, but couldn't find any information is user guidesPublications: NoAggregate Data: No

U.S. Home Language Survey Data (ICPSR 132781)

Released/updated on: 2021-02-18
Home language surveys (HLS) are widely used by states as an initial screening tool to determine whether students should receive English as a Second Language (ESL) services. Parents/guardians are asked to complete the surveys when enrolling a student into a school. We collected surveys from the 50 states and the District of Columbia. We completed them as if we were the parent/guardian of six fictitious case students. Research questions were: 1. How do HLS vary from state to state, if at all? What kinds of questions do they ask? 2. How do HLS across the 50 states and the District of Columbia identify, or not, six fictitious students for further ESL screening? We found that states and USDOE-approved HLS questions identified students differently due to unclear questions, such as asking bilingual families to name one dominant language.

Shining Rock Wilderness: 1990 visitor survey data (ICPSR 249505)

Released/updated on: 2026-06-07
Time period: 1990-06-01--1990-10-01
This data publication contains 1990 survey data for two different studies conducted in the Shining Rock Wilderness, which is in the Pisgah National Forest of western North Carolina. The first is a trend study to understand changes in visitor characteristics and the other was a study to understand knowledge and behavior about campsite selection and low-impact camping. Data for the ‘trend study’ were collected through a survey of visitors to the Shining Rock Wilderness. Visitors were contacted at trailheads, and those that agreed to participate in the study received a mailback survey, resulting in two data sets from two different survey instruments: visitor contact data and mailback survey data. Data for the second, ‘behavior and knowledge study’, was obtained from contacts and observations at campsites by Wilderness rangers. Two data sets (from two different survey instruments) were the result of the onsite information and observations and the mailback survey.

CDC BRFSS Annual Survey Data 1989-2023 (ICPSR 240401)

Released/updated on: 2025-11-18
Time period: 1989-01-01--2023-01-01
The Behavioral Risk Factor Surveillance System (BRFSS) is the nation’s premier system of health-related telephone surveys that collect state data about US residents regarding their health-related risk behaviors, chronic health conditions, health-care access, and use of preventive services. Established in 1984, BRFSS collects data in all 50 states as well as the District of Columbia and participating US territories. BRFSS completes more than 400,000 adult interviews each year, making it the largest continuously conducted telephone-based health survey system in the world.
By collecting behavioral health-risk data at the state and local level, BRFSS has become a powerful tool for customizing and planning health promotion activities. BRFSS is a go-to resource for health data scientists, researchers, other federal agencies, national health organizations, and state and local governments. In addition, countries across the globe have sought technical assistance from CDC to develop similar surveillance systems. BRFSS is also a data source for other tools and systems, such as CDC’s Population Level Analysis and Community Estimates (PLACES), CDC’s Chronic Disease Indicators, and Healthy People 2030.In early 2025, BRFSS data on the CDC website was changed to remove questions related to transgender people and genders besides M/F. This data was downloaded from an earlier capture of the BRFSS Annual Survey Download Page before the changes from December 2024 and January 2025 from the Wayback Machine (Internet Archive).

Survey Data on Psychological Determinants of Sustainable Packaging Behavior (ICPSR 236745)

Released/updated on: 2025-07-20
Time period: 2024-07-01--2024-12-31
This study focuses on understanding the psychological and systemic factors that influence the adoption of sustainable packaging practices among small and medium-sized enterprises (SMEs) in the food and beverage (F&B) sector in Mui Ne, a rapidly developing coastal tourism area in Vietnam. The central objective was to examine how targeted training could influence key behavioral determinants related to reducing single-use plastic (SUP) packaging. Grounded in the Theory of Planned Behavior (TPB), the study explores how participants’ attitudes, subjective norms, perceived behavioral control, and behavioral intentions toward eco-friendly packaging might change through a structured training program. To support this, the research integrated Soft Systems Methodology (SSM) to investigate contextual, institutional, and stakeholder dynamics contributing to SUP use. LEGO® SERIOUS PLAY® (LSP®) was incorporated as an experiential learning tool to facilitate reflection, problem structuring, and co-creation of sustainable packaging strategies. The training was delivered to 36 representatives from local F&B businesses, and data were collected through pre- and post-training questionnaires aligned with TPB constructs. The primary research questions guiding the study were: (1) To what extent can training based on behavioral and systems frameworks influence SMEs' psychological readiness to adopt sustainable packaging practices? and (2) What changes, if any, occur in participants’ attitudes, perceived social norms, perceived behavioral control, and behavioral intentions regarding eco-friendly packaging before and after the intervention? This description summarizes the conceptual foundation and research focus of the study and outlines the topics explored through empirical data collection and analysis.

Business Careers High School Mentor Survey Data (ICPSR 188321)

Released/updated on: 2023-04-07
Past research examining mentoring programs have explained the benefits student mentees received from having an adult as a mentor. For the mentee, the documentation shows that mentoring relationships have positive impacts on academic achievement, social attitudes, communication skills, and career goals (Mentoring.com, 2018). However, there has been very little research from the perspective of the mentor regarding their experiences of being in a mentoring relationship. This qualitative study will build upon the Berning (2013) study that extracted the thoughts and opinions of retiree and teen mentors who worked with elementary students. A recommendation from the Berning report suggested further studies need to be done on adults still involved in the workplace giving their off time to be mentors. The Business Careers High School mentoring program matches high school students with adult business professionals in the San Antonio community. Using an online questionnaire, mentors in this program were surveyed to further explore the themes developed in the Berning study.

Tailored Teen Alcohol and Violence Prevention in the Emergency Room, 2006-2009 [Flint, Michigan] (ICPSR 36732)

Released/updated on: 2017-05-26
Geographic coverage: Flint, United States, Michigan
Time period: 2006-01-01--2009-01-01

The Tailored Teen Alcohol and Violence Prevention in the Emergency Room survey screened 3,338 adolescents in an urban emergency department (ED) over a 30-month collection period. Eligible adolescents who self-reported alcohol misuse and violence were asked to participate in a longitudinal study to assess the efficacy of various brief interventions (BIs) at reducing peer violence, victimization, and substance abuse.

Patients aged 14 to 18 years who presented for medical illness or injury were eligible for screening (see Sampling exclusions). Recruitment occurred between 12pm and 11pm, 7 days a week (September 2006-September 2009), excluding major holidays. Adolescent patients identified from electronic logs were approached by research assistants in waiting rooms or treatment spaces. Following obtainment of written consent (and assent and parent/guardian consent if under 18 years of age), participants self-administered a 15-minute computerized survey with audio. After completing the survey, participants reporting both past-year aggression (peer, dating, weapon carriage/use) and alcohol consumption were eligible to enroll in the longitudinal study. Participants reporting only 1 behavior (aggression or alcohol use) were not eligible.

Following obtainment of written consent (and assent and parent/guardian consent if under 18 years of age) for the longitudinal study, participants self-administered a computerized baseline assessment. Participants were informed that they would be randomly assigned to 1 of 3 groups: computer session, counselor session, or brochure. Participants were blinded to condition assignment until after the baseline assessment. After the baseline, participants were randomized and received the therapist brief intervention, computer brief intervention, or control brochure during the ED visit.

Boundary Waters Canoe Area Wilderness: 1991 visitor survey data (ICPSR 249455)

Released/updated on: 2026-06-07
Time period: 1991-05-01--1991-09-01
The Boundary Waters Canoe Area Wilderness (BWCAW) is in the Superior National Forest in northern Minnesota. The BWCAW receives the most use of any wilderness in the country, and has been the location of several studies. The data included in this publication are from a 1991 study aimed at two purposes: (1) to replicate, as nearly as possible, a similar 1969 study in the BWCAW and; (2) to examine the effects of a Forest Service proposal to reduce the number of entrance permits in hopes of increasing opportunities for solitude and reducing resource damage. Between May and September 1991, a sample of visitors was obtained from face-to-face contacts at boat-launch points or trailheads. Mailback surveys were then sent out to these visitors. Data were collected from the same 14 entry points as the 1969 study on approximately the same days of the use season; additionally, the sample was expanded to represent lower use level access points better than they had in 1969 to accomplish purpose number two above. This data publication includes the results from 295 mailback surveys.

This collection contains data integrated from the two components of the Consumer Expenditure Survey, the Diary Survey and the quarterly Interview Survey, for the years 1984-1996. The integrated data provide a complete accounting of consumer expenditures and income, which neither component alone is designed to do. For the Diary Survey, consumer units complete a diary of expenses for two consecutive one-week periods. The diary survey is designed to obtain data on frequently purchased items, such as food and beverages, housekeeping supplies, etc., that respondents are less likely to recall over longer periods of time. For the Interview Survey, consumer units report information to an interviewer once every three months for five consecutive quarters. This survey is designed to obtain data on expenditures and income that respondents can be expected to recall for a period of three months or longer, such as property or automobile purchases, and those that occur on a regular basis, such as rent, utility bills, and insurance premiums. The standard tables include age of reference person, composition of the consumer unit, size of the consumer unit, number of earners in the consumer unit, income before taxes, occupation, quintiles of income before taxes, housing tenure, race, type of area (urban-rural), and region of residence. There are also cross-tabulated tables that include age by income, consumer unit size by income, region by income before taxes, Metropolitan Statistical Areas by the four census regions, and single persons by age and by income.

Replication data for: Uncertainty and Economic Activity: Evidence from Business Survey Data (ICPSR 114269)

Released/updated on: 2019-10-12
This paper uses survey expectations data to construct empirical proxies for time-varying business-level uncertainty. Access to the micro data from the German IFO Business Climate Survey permits construction of uncertainty measures based on both ex ante disagreement and ex post forecast errors. Ex ante disagreement is strongly correlated with dispersion in ex post forecast errors. Surprise movements in either measure lead to significant reductions in production that abate fairly quickly. We extend our analysis to US data, measuring uncertainty with forecast disagreement from the Business Outlook Survey. Surprise increases in forecast dispersion lead to more persistent reductions in production than in the German data. (JEL C53, C83, D81, E23, E27, E32, E37)

National Medical Care Expenditure Survey, 1977: Health Insurance/Employer Survey Data (ICPSR 8627)

Released/updated on: 2006-03-30
Geographic coverage: United States
The purpose of the National Medical Care Expenditure Survey (NMCES) was to assess the cost and extent of health insurance in the United States. Information on health insurance coverage was obtained in a household survey, then verified and supplemented with information from the Health Insurance/Employer Survey (HIES). Insurance companies, employers, unions, and other organizations identified in the household survey as sources of private insurance coverage were asked to verify reported coverage, to provide information on each subscriber's coverage and its cost, the parties responsible for payment of premiums, and the availability of alternative or optional plans. This release includes two distinct datasets. One contains information for each individual respondent in the NMCES component on private health insurance status as verified in the HIES, and includes data on premiums and sources of premium payment. The other contains information for each individual respondent 65 years or older with private insurance as verified in the HIES, as well as information on the services covered by their private insurance benefits.

Timber survey data from 1911 in the Greenhorn Mountains, Sequoia National Forest (ICPSR 249540)

Released/updated on: 2026-06-07
This data publication contains tabular data with measurements of tree and shrub data for a set of transects located in the Greenhorn Mountains, Sequoia National Forest in California. The transects represent a systematic timber inventory collected across a large mixed-conifer and ponderosa pine dominated landscape by the U.S. Forest Service in 1911. Trees were tallied by species and diameter within 20 x 400 meter strips that spanned the center of quarter-quarter sections (QQs) delineated by the Public Land Survey System. Shrub cover was determined using an ocular estimate and recorded qualitatively by species. Tabular data specifically include cover estimates for Chamaebatia foliolosa and an estimate for all other species as a whole; basal area for the following live trees ≥ 30.5 centimeters (cm) at diameter at breast height (dbh): Abies concolor, Calocedrus decurrens, Pinus lambertiana, Pinus ponderosa, and all conifer trees; as well as density of live conifer trees in three different dbh classes. Also included in this publication are scans of the original data collection sheets recorded in 1911.

Data and Code for: What Do Survey Data Tell Us about US Businesses? (ICPSR 117021)

Released/updated on: 2020-11-23
Time period: 1988-01-01--2016-01-01
This paper examines the reliability of survey data on business incomes, valuations, and rates of return, which are key inputs for studies of wealth inequality and entrepreneurial choice.  We compare survey responses of business owners with available data from administrative tax records, brokered private business sales, and publicly traded company filings and document problems due to nonrepresentative samples and measurement errors across several surveys, subsamples, and years.  We find that the discrepancies are economically relevant for the statistics of interest.  We investigate reasons for these discrepancies and propose corrections for future survey designs.

Data and Code for: Temperature, Worker Productivity, and Adaptation: Evidence from Survey Data Production (ICPSR 141721)

Released/updated on: 2022-12-08
Time period: 1990-01-01--2010-12-01
This paper estimates the impact of daily weather on worker productivity by using household survey data to study interviewers. Using data from over 9,000 Demographic and Health Survey interviewers in 46 countries, I find that interviewers complete 13.6 percent fewer interviews per hour on the hottest and most humid days. Workers maintain the same total output by starting earlier in the day and spending more time on each interview at the expense of spending more hours in the field with the same total pay. In addition, interviewers become differentially less productive on tasks that are less easily monitored. These findings are important not only because temperatures are predicted to rise significantly over the next century, but also because they shed light on how adaptation by workers to adverse conditions can be costly in ways not captured by aggregate productivity measures such as GDP.

Time period: 1998-01-01--2017-01-01

The Global Entrepreneurship Monitor [GEM] research program was developed to provide comparisons among countries related to participation of adults in the firm creation process. The initial data was assembled as a pretest of five countries in 1998 and by 2012 over 100 countries had been involved in the program. The initial design for the GEM initiative was based on the first US Panel Study of Entrepreneurial Dynamics, and by 2012 data from 1,827,513 individuals had been gathered in 563 national samples and 6 specialized regional samples.

This dataset is a harmonized file capturing results from all of the surveys. The procedure has been to harmonize the basic items across all surveys in all years, followed by implementing a standardized transform to identify those active as nascent entrepreneurs in the start-up process, as owner-managers of new firms, or as owner-managers of established firms. Those identified as nascent entrepreneurs or new business owners are the basis for the Total Entrepreneurial Activity [TEA] or Total Early-Stage index. This harmonized, consolidated assessment not only facilitates comparisons across countries, but provides a basis for temporal comparisons for individual countries.

Respondents were queried on the following main topics: general entrepreneurship, start-up activities, ownership and management of the firm, and business angels (angel investors). Respondents were initially screened by way of a series of general questions pertaining to starting a business, such as whether they were currently trying to start a new business, whether they knew anyone who had started a new business, whether they thought it was a good time to start a new business, as well as their perceptions of the income potential and the prestige associated with starting a new business. Demographic variables include respondent age, sex, and employment status.

Behavioral Risk Factor Surveillance System (BRFSS) Annual Survey Data, 1999-2019 (ICPSR 146342)

Released/updated on: 2021-09-03
Time period: 1999-01-01--2019-01-01
In 1984, the Centers for Disease Control and Prevention (CDC) initiated the state-based Behavioral Risk Factor Surveillance System (BRFSS)--a cross-sectional telephone survey that state health departments conduct monthly over landline telephones and cellular telephones with a standardized questionnaire and technical and methodologic assistance from CDC. BRFSS is used to collect prevalence data among adult U.S. residents regarding their risk behaviors and preventive health practices that can affect their health status. Respondent data are forwarded to CDC to be aggregated for each state, returned with standard tabulations, and published at year's end by each state. In 2011, more than 500,000 interviews were conducted in the states, the District of Columbia, and participating U.S. territories and other geographic areas.
The files in this deposit were downloaded from the CDC website by Julia Dennett, Yale University, and Toby Chaiken, J-PAL North America, and archived by Travis Donahoe, Harvard University and Michael Darisse, Cornell University.

Replication data for: Risk and Time Preferences: Linking Experimental and Household Survey Data from Vietnam (ICPSR 112336)

Released/updated on: 2019-10-11
We conducted experiments in Vietnamese villages to determine the predictors of risk and time preferences. In villages with higher mean income, people are less loss-averse and more patient. Household income is correlated with patience but not with risk. We expand measurements of risk and time preferences beyond expected utility and exponential discounting, replacing those models with prospect theory and a three-parameter hyperbolic discounting model. Comparable risk parameter estimates have been found for Chinese farmers, using our method. (C83, D12, O12, P38)

Gates Millennium Scholars (GMS) Survey Data Cohort 5, United States, 2004-2009 (ICPSR 34439)

Released/updated on: 2019-10-01
Geographic coverage: United States
Time period: 2004-01-01--2009-01-01

In 1999, the Bill and Melinda Gates foundation started the Gates Millennium Scholars Program (GMS), a 20-year initiative which intends to expand access to higher education for high achieving, low-income minority students. In addition to its academic objectives, GMS also has the goal of creating future leaders in minority groups. The program is administered by the United Negro College Fund (UNCF). Awardees can receive the scholarship for up to 5 years as an undergraduate and 4 years as a graduate student. The scholarship is renewable through graduate school in math, science, engineering, library science, and education.

In order to see how GMS has impacted students and to know how to better prepare minority students for college, the Bill and Melinda Gates Foundation has commissioned a survey of recipients. Cohorts are composed of both recipients and non-recipients. Non-recipients are defined as individuals who were asked to go on to the scholar confirmation/verification phase, but did not become a scholar for one or more reasons.

Baseline, first follow-up, second follow-up survey, and longitudinal survey data have been collected from both recipients and non-recipients.
