Consumer Expenditure Survey, 1992: Diary Survey (ICPSR 6318)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1992-01-01--1992-12-31
The ongoing Consumer Expenditure Survey (CES) provides a continuous flow of information on the buying habits of American consumers and also furnishes data to support periodic revisions of the Consumer Price Index. The survey consists of two separate components: (1) a quarterly Interview Survey in which each consumer unit in the sample is interviewed every three months over a 15-month period, and (2) a Diary Survey completed by the sample consumer units for two consecutive one-week periods. The Diary Survey contains consumer information on small, frequently purchased items such as food, beverages, food consumed away from home, gasoline, housekeeping supplies, nonprescription drugs and medical supplies, and personal care products and services. Participants were asked to maintain expense records, or diaries, of all purchases made each day for two consecutive one-week periods. Information was also elicited at the end of the two-week period on work experience, occupation, industry, retirement status, earnings from wages and salaries, net income from business or profession, net income from one's own farm, and income from other sources. The Consumer Unit Characteristics and Income (FMLY) files supply information on consumer unit characteristics, consumer unit income, and characteristics and earnings of the reference person and his or her spouse. A consumer unit consists of all members of a particular housing unit who are related by blood, marriage, adoption, or some other legal arrangement. Consumer unit determination for unrelated persons is based on financial independence. Member Characteristics (MEMB) files contain selected characteristics for each consumer unit member, including reference person and spouse. The Detailed Expenditures (EXPN) files present weekly data on expenditures at the Universal Classification Code (UCC) level, while the Income (DTAB) files contain weekly data on income at the UCC level. An additional file, Part 20, includes sample programs that can be used for various types of data extraction.

Consumer Expenditure Survey, 1992: Interview Survey (ICPSR 6372)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1992-01-01--1992-12-31
The ongoing Consumer Expenditure Survey (CES) provides a continuous flow of information on the buying habits of American consumers and also furnishes data to support periodic revisions of the Consumer Price Index. The survey consists of two separate components: (1) a quarterly Interview Survey in which each consumer unit in the sample is interviewed every three months over a 15-month period, and (2) a Diary Survey completed by the sample consumer units for two consecutive one-week periods. The Interview Survey was designed to collect data on major items of expense, household characteristics, and income. The expenditures covered by the survey are those that respondents can recall fairly accurately for three months or longer. In general, these expenditures include relatively large purchases, such as those for property, or expenditures that occur on a fairly regular basis, such as rent, utilities, or insurance premiums. Excluded are nonprescription drugs, household supplies, and personal care items. The Consumer Unit Characteristics and Income (FMLY) files in this collection contain consumer unit characteristics, consumer unit income, and characteristics and earnings of both the reference person and the spouse. Summary expenditure data are also provided. The Member Characteristics and Income (MEMB) files present selected characteristics for each consumer unit member, including reference person and spouse. Each record in the FMLY and MEMB files consists of three months of data. Detailed Expenditures (MTAB) files provide monthly data at the Universal Classification Code (UCC) level. In these files expenditures for each consumer unit are classified according to UCC categories and are specified as gifts or nongifts. There may be more than one record for a UCC in a single month if that is what was reported to the interviewer. The Income (ITAB) files supply monthly data at the UCC level for consumer unit characteristics and income. An additional file, Part 24, includes sample programs that can be used for various types of data extraction.

Primary Care Judgments of Nurses and Physicians, 1976-1978: Clinical Simulation Test -- Chronic Obstructive Pulmonary Disease Data (ICPSR 7731)

Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1976-01-01--1978-12-31
This data collection contains four files of the Clinical Simulation Test for chronic obstructive pulmonary disease, an instrument developed by the Primary Care Judgements of Nurses and Physicians Research Project to empirically assess the clinical judgements of physicians and nurses in relation to chronic obstructive pulmonary disease in the period 1976-1978. The purpose of the study was to measure the clinical judgments of health professionals in relation to those of a panel of eight national experts in the specific area of chronic obstructive pulmonary disease. The instrument simulates the clinical processes from presentation of the chief complaint of a 53-year-old Caucasian male with chronic obstructive pulmonary disease through diagnoses and treatment. The Clinical Simulation Test (Part 1) was given to 200 respondents who were divided into six groups: family practice physicians, nurse practitioners with master's degrees, certified nurse practitioners, public health nurses, pre-medical students, and nursing students. The test contains 13 sections and three diagnostic tests. Nine of the test sections required the respondents to choose from a list of possible treatment actions. Four sections were open-ended and required respondents to identify relevant patient data or to list patient problems. During the process, respondents chose appropriate procedures from among a wide range of possible choices. Items also include an evaluation of the test instrument by the respondents, a proficiency scale which is scored by means of a computer program (Part 2), and the responses of 2 panels of experts used for the purpose of test instrument validation (Parts 3 and 4). Demographic items specify age, sex, education, professional preparation, residency program, specialty, position, and disease management experience of respondents. See the related collection, PRIMARY CARE JUDGMENTS OF NURSES AND PHYSICIANS, 1976-1978: CLINICAL SIMULATION TEST -- HYPERTENSION DATA (ICPSR 7732).

Decision-Related Research on the Organization of Service Delivery Systems in Metropolitan Areas: Public Health (ICPSR 7374)

Released/updated on: 1992-02-16
Geographic coverage: United States
Time period: 1970-01-01--1975-12-31
This study represents one of four research projects on service delivery systems in metropolitan areas, covering fire protection (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: FIRE PROTECTION [ICPSR 7409]), police protection (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: POLICE PROTECTION [ICPSR 7427]), solid waste management (DECISION-RELATED RESEARCH ON THE ORGANIZATION OF SERVICE DELIVERY SYSTEMS IN METROPOLITAN AREAS: SOLID WASTE MANAGEMENT [ICPSR 7487]), and public health (the present study). All four projects used a common unit of analysis, namely all 200 Standard Metropolitan Statistical Areas (SMSAs) that, according to the 1970 Census, had a population of less than 1,500,000 and were entirely located within a single state. In each project, a limited amount of information was collected for all 200 SMSAs. More extensive data were gathered within independently drawn samples of these SMSAs, for all local geographical units and each administrative jurisdiction or agency in the service delivery areas. Two standardized systems of geocoding -- the Federal Information Processing Standard (FIPS) codes and the Office of Revenue Sharing (ORS) codes -- were used, so that data from various sources could be combined. The use of these two coding schemes also allows users to combine data from two or more of the research projects conducted in conjunction with the present one, or to add data from a wide variety of public data files. The delivery of public health services was investigated in 200 SMSAs plus Minneapolis and St. Paul. The basic data collection effort involved the use of public data sources as well as proprietary data from the American Medical Association (AMA) and the Commission on Professional and Hospital Activities (CPHA). Because of the proprietary nature of some of the data and for the preservation of confidentiality, all analyses were performed at the SMSA level. Unlike the other three related research projects, the present study does not provide disaggregated units of analysis such as the administrative jurisdiction, the individual hospital, or other facilities. Variables describe the characteristics of available professionals and facilities, regulatory factors reflecting the impact of federal and state programs available in the area, and financing factors, including the coverage of state Medicaid programs, Blue Cross and Blue Shield, and Medicare programs. Information is also provided regarding the demographic and socioeconomic characteristics of the population served in each SMSA.

Nationally Representative Behavioral Risk Factor Surveillance System (BRFSS) Cognitive Decline and Caregiver Datasets, 2019-2022 (ICPSR 244591)

Released/updated on: 2026-05-27
Time period: 2019-01-01--2022-12-31
This code and corresponding data files are intended for use in cognitive decline and Alzheimer’s disease and related dementias (ADRD) research. The two datasets include the most recently available data from each state during 2019-2022 where a US state participated in either the Cognitive Decline Module or the Caregiver Module. All data are derived from the Behavioral Risk Factor Surveillance System (BRFSS). BRFSS is a system of phone surveys that collect state data on health-related risk behaviors, chronic health conditions, and the use of preventive services in the U.S. adult population. BRFSS is conducted in three waves, or “versions,” each year. Core questionnaires from BRFSS must be asked of all respondents in each wave and are asked, with some exceptions, in all 50 U.S. states, D.C., and some U.S. territories. Individual states may opt to include additional optional modules, such as the Cognitive Decline Module and Caregiver Module, that may be asked in some or all the waves. Data is weighted to the state-level. Taken together, researchers can generate either state-level estimates or semi-nationally representative estimates when including all states. Both datasets include: cleaned sociodemographic information on respondents’ state, age, sex, race, education, and marital status; general, mental, and physical health; and questions from either the Caregiver Module or the Cognitive Decline Module for all states who participated in the respective optional module. Brief and detailed summaries of the variables available in these datasets along with more detailed descriptions of performed data cleaning can be found in the provided data dictionaries. The respective dictionaries also include tables showing which states, years, and versions are used. Note that for each dataset, there are 2-3 states that did not participate in the included years. SAS, Stata, and CSV data file formats are provided as are the full coding scripts used in Stata.

Bynum 1-Year Standard Method for identifying Alzheimer’s Disease and Related Dementias (ADRD) in Medicare Claims data (ICPSR 183523)

Released/updated on: 2023-06-22
Here, you will find resources to use the Bynum-Standard 1-Year Algorithm including a README file that accompanies SAS and Stata scripts for the 1-Year Standard Method for identifying Alzheimer’s Disease and Related Dementias (ADRD) in Medicare Claims data.  There are seven script files (plus a parameters file for SAS [parm.sas]) for both SAS and Stata. The files are numbered in the order in which they should be run; the five “1” files may be run in any order.The full algorithm requires access to a single year of Medicare Claims data for (1) MedPAR, (2) Home Health Agency (HHA) Claims File, (3) Hospice Claims File, (4) Carrier Claims and Line Files, and (5) Hospital Outpatient File (HOF) Claims and Revenue Files. All Medicare Claims files are expected to be in SAS format (.sas7bdat).For each data source, the script will output three files*:
  1. Diagnosis-level file: Lists individual ADRD diagnoses for each beneficiary for a given visit. This file allows researchers to identify which ICD-9-CM or ICD-10-CM codes are used in the claims data.
  2. Service Date-level file: Aggregated from the Diagnosis-level file, this file includes all beneficiaries with an ADRD diagnosis by Service Date (date of a claim with at least one ADRD diagnosis).
  3. Beneficiary-level file: Aggregated from the Service Date-level file, this file includes all beneficiaries with at least one* ADRD diagnosis at any point in the year within a specific file
* The algorithm combines the Carrier and HOF files at the Service Date-level. The final combined Carrier and HOF Beneficiary-level file includes those with at least two (2) claims that are seven (7) or more days apart.​A final combined file is created by merging all Beneficiary-level files. This file is used to identify beneficiaries with ADRD and can be merged onto other files by the Beneficiary ID (BENE_ID).With appreciation & acknowledgement to colleagues from a grant funded by the NIA for their involvement in development & validation of the Bynum-Standard 1-Year Algorithm

Survey of Consumer Finances, 1971 (ICPSR 7451)

Released/updated on: 1992-02-16
Geographic coverage: United States
Time period: 1971-01-01--1971-12-31
This data collection is one in a series of financial surveys of consumers conducted annually since 1946. In a nationally representative sample, the head of each family unit was interviewed. Starting in 1966, in order to examine the effect that increased car ownership was having on American families, the data collected in this series were organized so that they could be analyzed by both family unit and car unit. The 1971 data are based on car unit. Survey questions regarding automobiles included number of drivers and car owners in the family, make and model of each car, purchase method, car financing and installment debt, and expectations of car purchases in the coming year. Other questions in the 1971 survey covered the respondent's attitudes toward national economic conditions (e.g., the effect of United States relations with Vietnam, Cambodia, and in the Middle East, inflation and unemployment on United States business) and price activity, as well as the respondent's own financial situation. Other questions examined the family unit head's occupation, and the nature and amount of the family's income, debts, liquid assets, changes in liquid assets, savings, investment preferences, and actual and expected purchases of major durables. In addition, the survey explored the subject of housing and neighborhood characteristics. Questions in this survey also focused on credit card use and purchases. Personal data include age and education of head, household composition, political affiliation, and occupation.

Released/updated on: 2024-07-30
Geographic coverage: United States, Maine
Time period: 2006-01-01--2014-12-31

In partnership with the Maine Department of Health and Human Services, this study analyzed approximately 200 case files of Maine Adult Protective Services (APS) substantiated investigations of financial exploitation that were opened and completed from 2007 through 2012. The case files included detailed information about the types of abuse individuals experienced, their functional limitations, and severity of risk status. The research team linked the case files with the individuals' Medicare and Medicaid claims data from 2006 through 2014 to examine their claims experience one year prior to APS contact, during their APS event year, and two years following their APS event year. Using a quasi-experimental design, the research team established health care use and cost profiles of the APS clients and compared their profiles to matched controls in the general older population. The project aimed to advance knowledge of the financial impact of elder abuse.

This round of Euro-Barometer surveys queried respondents on standard Euro-Barometer measures such as public awareness of and attitudes toward the Common Market and the European Union (EU), and focused on perceptions about and factors affecting blood and plasma donation. Questions solicited opinions about the way blood and plasma are collected and handled, reasons for donating, understanding of the differences between blood and plasma, the necessity of rewards for donating, and sources of information about blood or plasma donation. Respondents were also surveyed about their perceptions of product quality based on country of manufacture, cross-border purchases and customs experiences, a single European currency, women's opinions on EU matters, tobacco smoking habits, AIDS risks, and perceived cancer risks of food products. On EU matters, respondents were asked how well-informed they felt about the EU, what sources of information about the EU they used, whether their country had benefited from being an EU member, and the extent of their personal interest in EU matters. This survey also includes respondent opinions and party preferences for the June 1994 European elections. Demographic and other background information was gathered on number of people residing in the home, size of locality, home ownership, trade union membership, region of residence, and occupation of the head of household, as well as the respondent's age, sex, marital status, education, occupation, work sector, religion, religiosity, subjective social class, left-right political self-placement, and opinion leadership.

Survey of Income and Program Participation (SIPP) 1993 Panel (ICPSR 6886)

Released/updated on: 1999-10-04
Geographic coverage: United States
Time period: 1992-10-01--1996-01-31

This data collection is part of a longitudinal survey designed to provide detailed information on the economic situation of households and persons in the United States. These data examine the distribution of income, wealth, and poverty in American society and gauge the effects of federal and state programs on the well-being of families and individuals.

There are three basic elements contained in the survey. The first is a control card that records basic social and demographic characteristics for each person in a household, as well as changes in such characteristics over the course of the interviewing period. The second element is the core portion of the questionnaire, with questions repeated at each interview on labor force activity, types and amounts of income, participation in various cash and noncash benefit programs, attendance in post-secondary schools, private health insurance coverage, public or subsidized rental housing, low-income energy assistance, and school breakfast and lunch participation. The third element consists of topical modules, which are series of supplemental questions asked during selected household visits.

Topical modules include some core data to link individuals to the core files.

The Wave 1 Topical Module covers recipiency history, which includes welfare and other aid, and employment history. The Wave 2 Topical Module includes data on work disability, education and training, marital, migratory, and fertility histories, and household relationships. The Wave 3 Topical Module covers work schedule, child care, child support agreements, support for nonhousehold members, functional limitations and disability, and utilization of health care services. The Wave 4 Topical Module covers selected financial assets, medical expenses and work disability, real estate, shelter costs, dependent care, and vehicles. The Wave 5 Topical Module covers annual income, retirement accounts, and taxes in one file and school enrollment and financing in the second file. The Wave 6 Topical Module covers the same subjects as the Wave 3 Topical Module, but in greater detail, and includes a section on children's well-being. The Wave 7 Topical Module covers assets and liabilities, medical expenses and work disabilities, real estate, shelter costs, dependent care, and vehicles. The Wave 8 Topical Module covers school enrollment and financing. The Wave 9 Topical Module covers retirement expectations and pension plan coverage, work schedule, child care, children's well-being, child support agreements, support for nonhousehold members, and basic needs, including ability to meet expenses, food adequacy, and minimum income.

Geriatric Home Care Utilization: San Francisco, 1968-1975 (ICPSR 7853)

Released/updated on: 2006-03-30
Geographic coverage: San Francisco, United States, California
Time period: 1968-01-01--1975-12-31
This data collection reported on geriatric clients served by San Francisco Home Health Services, Inc. (SFHHS) between 1968 and 1975. The study was designed to document and analyze the natural history of home care service use from entry to exit, noting what types of users were in a home care agency's program and how intensively services were utilized. The study also identified outcome categories useful for response to public policy questions on the effectiveness of various service types in meeting geriatric needs. Also examined was the relationship of home care use to nursing home entry, and to the need for other services. In Part 1, data for 2,435 clients were gathered from case records at SFHHS. Variables used in the analysis include entry characteristics (e.g, age, sex, condition, living arrangement, and contextual variables such as referral source, prior source of care, and payment type), duration, intensity, and type of service utilization, as well as discharge or exit status. Some of these are calculated variables derived from each case's accumulated monthly service records (found in their raw form in Part 2). Part 2 contains 35,729 client monthly service records, which are distributed as raw data as received from SFHHS. Variables include billing date, pay plan, and frequency and intensity of assistance.

Indonesian Family Life Survey, 1993 (ICPSR 6706)

Released/updated on: 2006-01-12
Geographic coverage: Kalimantan, Java, Bali, Sumatra, West Nusa Tenggara, Global, Indonesia, Sulawesi
Time period: 1993-01-01--1993-12-31

This release of the 1993 Indonesian Family Life Survey (IFLS-1-PR) is a revised and restructured version of the Wave 1 data. This data collection provides a broad range of economic, demographic, and health information at both the household and community levels across 13 provinces on the islands of Java, Sumatra, Bali, West Nusa Tenggara, Kalimantan, and Sulawesi. A sample of 7,224 households was interviewed during August 1993 through January 1994. Household-level data cover topics such as household characteristics, income, education of both adults and children, marriage histories, inter-household transfers, pregnancy history, and knowledge and use of contraceptives. At the community-facility level, information was gathered from village leaders and heads of village women's groups in each of the 321 enumeration areas (EAs) where the households were located. Questions were asked regarding community characteristics (transportation, water and sanitation, history of schools, and availability of health facilities), nurses, midwives, and paramedics (facility management and family planning history, vignettes on types of care), and traditional health practitioners (buying or making herbal medicines or using services of traditional practitioners, rituals, and incantations). When the household data are combined with the community-facility data, the 1993 Indonesian Family Life Survey provides a unique look at areas of fertility, family planning, infant and child health, education, migration, employment, and the social, economic, and health status of over 7,000 households in a diverse setting during a period of rapid demographic and socioeconomic change.

As of June 2015, there are four waves of data for the IFLS. However, a fifth wave of data collection has begun. Please see the IFLS Web site for more information on how to obtain these data.

New York City Health and Nutrition Examination Survey (NYC HANES), 2004 (ICPSR 31421)

Released/updated on: 2011-11-03
Geographic coverage: New York City, United States, New York (state)
Time period: 2004-06-02--2004-12-19
The New York City Department of Health and Mental Hygiene, with support from the National Center for Health Statistics, conducted the New York City Health and Nutrition Examination Survey (NYC HANES) to improve disease surveillance and establish citywide estimates for several previously unmeasured health conditions from which reduction targets could be set and incorporated into health policy planning initiatives. NYC HANES also provides important new information about the prevalence and control of chronic disease precursors, such as undiagnosed hypertension, hypercholesterolemia, and impaired fasting glucose, which allow chronic disease programs to monitor more proximate health events and rapidly evaluate primary intervention efforts. Study findings are used by the public health community in New York City, as well as by researchers and clinicians, to better target resources to the health needs of the population. The NYC HANES data consist of the following six datasets: (1) Study Participant File (SPfile), (2) Computer-Assisted Personal Interview (CAPI), (3) Audio Computer-Assisted Self-Interview (ACASI), (4) Composite International Diagnostic Interview(CIDI), (5) Examination Component, and (6) Laboratory Component. The Study Participant File contains variables necessary for all analyses, therefore, when using the other datasets, they should be merged to this file. Variable P_ID is the unique identifier used to merge all datasets. Merging information from multiple NYC HANES datasets using SP_ID ensures that the appropriate information for each SP is linked correctly. (SAS datasets must be sorted by SP_ID prior to merging.) Please note that NYC HANES datasets may not have the same number of records for each component because some participants did not complete each component. Demographic variables include race/ethnicity, Hispanic origin, age, body weight, gender, education level, marital status, and country of birth.
