Occasionally, PSID creates supplemental data that includes many interesting calculated variables. Most of these data are also available in the Data Center.


Disability and Use of Time (DUST) : 2009

The final release of the 2009 Disability and Use of Time (DUST) research file is now available. The purpose of DUST was to collect information from older couples in PSID families about disability, time use, and well being. PSID heads and wives were each interviewed twice about two randomly selected days -- one week day and one weekend day. Information was obtained using time diaries about what respondents did, where they were, who did the activities with them, who else was there, how they felt, and (for household and care-related activities) for whom the activity was carried out. Diaries also include more detailed measures of well-being for 3 randomly selected activities per diary. The first interview also included in-depth questions about the respondent's health, functioning, well-being, and stylized time use/participation measures.

The ZIP file contains 4 sets of data files and setups for reading them, 4 PDF codebooks, 2 box and arrow questionnaire documents, and a detailed User's Guide.

This project was supported by a program project grant from the National Institute on Aging, 5P01AG029409.

Transition into Adulthood (TA)  (release 1): 2011

The preliminary 2011 Transition into Adulthood data file (TA-2011) is now available.

This data file represents the fourth wave of the Transition into Adulthood Study (TA) which was introduced in 2005 to capture data on the developmental pathways and outcomes of children who participated in the PSID Child Development Study as they transitioned into young adulthood. This study fills a gap between detailed information about development up through adolescence, and detailed information on adulthood once PSID panel members assume the role of economic independence as heads and spouses in the main study. The module collects data on health and emotional well-being, time use, community involvement, self identity and perception, expectations for the future, family, peer, and romantic relationships, work, schooling, and more. The interview domains are coordinated with the CDS adolescent measures and the PSID employment and health measures, and additionally provide new questions unique to this developmental stage.

The ZIP file contains 1 SAS data set, text files containing contents and frequencies, and a box and arrow questionnaire. These files include all the information collected except data about employment. These files are preliminary and values may change before final and complete files are released later.

This project was supported by a grant from the Eunice Shriver Kennedy National Institute on Child Health and Human Development, 1R01HD059779-01A1.

T-2 Family Income Files: 2003 and 2005

After the 1997 interviewing year, the PSID was forced to switch to biennial interviewing due to funding considerations. Because annual family income measures are so central to the PSID, plans were made to try to collect at least a rough measure of income for the "off" year. Additionally, welfare reform was instituted across the U.S. in the late 1990s, and measurement of those effects was very important. Question sequences covering the t-2 income and welfare reform consequences are combined in Section R of the 1999, 2001, 2003, 2005 and 2007 questionnaires. In 1999-2007 there have been many versions of Section R, exploring the use of more detail and less detail by income component. Most of the information pertains to families and is available on the main family-level file, but for 2005, earnings and assets relate to specific individuals and were therefore aggregated to the family level for ease of use and are available on this file.

T-2 Individual Income Files: 1999 and 2001

After the 1997 interviewing year, the PSID was forced to switch to biennial interviewing due to funding considerations. The next wave was collected in 1999. Because annual family income measures are so central to the PSID, plans were made to try to collect at least a rough measure of income for the "off" year. Additionally, welfare reform was instituted across the U.S. in the late 1990s, and measurement of those effects was very important.
Question sequences covering the t-2 income and welfare reform consequences are combined in Section R of the 1999 and subsequent questionnaires. Most of the information pertains to families and is available on the main family-level file, but several items, such as work, earnings, and public assistance payments, relate to specific individuals and are available on these files.

Hours of Work and Wages File: 1994-2001

Note: Also available in the Data Center
Note:Work Hours and Wages 2003 data are available in the main family data files.

Historically (prior to the 1993 survey), the hourly wage calculation was accomplished substantially by preprocess editing of paper questionnaires - making case by case judgment easier. Here we calculated such variables by extensive programming code and then, ex post, applied judgmental hand editing to the remaining 'problem' cases.

Health Care Burden File: 1993

The 1993 Health Care Burden (HCB) file contains the detailed information collected in the 1993 PSID interview concerning health events of the elderly and their (primarily financial) burden on immediate and extended families. The file contains one record for each older Head, Wife/"Wife", other family unit member and parent of Head or Wife/"Wife". The purpose of the HCB supplements is to help provide a better understanding about the impact of these events on the families of the elderly. These supplements were funded by the National Institute for Aging.

OFUM Income Detail File: 1993

Beginning in 1993, the main family and individual files include somewhat less income detail about individuals who are not current Heads, Wives and long-term female co-habitors than was the past custom. Unlike the 1992 and earlier family files, the 1993 family file does not include separate taxable amounts for up to five earners, although the sum of all Other Family Unit Members' (OFUMs') taxable income is still present. The portion of the main individual file that contains 1993 data has three income variables: one for labor income, one for asset income, and one for total transfer income of each person. It does not contain the type variables for taxable and transfer incomes reported in 1993.

These dearths are more than compensated for with the 1993 OFUM Income Detail File. For each OFUM, it contains separate sets of variables for labor income from up to four jobs; two types of asset income, interest and other assets; and the eleven types of transfer income recognized by the PSID.

Parent Health Supplement: 1991

The supplement was conducted with a grant from the National Institute on Aging through the Rand Corporation.

In 1991, the PSID asked an extensive questionnaire supplement about parents of Head and Wife/"Wife". Because of the supplement's length, it is available as a separate data file. The PHS data structure includes one record for each 1991 Head or Wife/"Wife" who had an eligible parent and who consented to the supplement. Thus, if a consenting Head and Wife/"Wife" each had eligible parents, two records exist on the supplemental file-- one for each pair of parents.

The supplement focused on circumstances and events at the time when a parent was no longer able to care for him or herself. To be eligible, at least one parent had to be living and age 70 or more by May 31, 1991 or deceased no earlier than 1980 and age 70 or more at death. Since screening all Heads and Wives/"Wives" to determine whether parents qualified for the supplement would have been lengthy and wasteful of precious interviewing time, PSID data from the 1988 Time and Money Help Supplement, which asked, among many other things, about age and sentience of parents, was used to "pre-qualify" them.

The ZIP file contains an ASCII data file, associated SAS and SPSS data definition statements, an OSIRIS dictionary and a documentation file in ASCII format with page breaks.

Telephone Health and Self Administered Questionnaire Supplement: 1990

As part of the 1990 interviewing effort, funds were granted to Lee Lillard of the Rand Corporation by the National Institute on Aging to supplement the PSID with data about older panel members in the core (but not Latino) sample. Two supplemental data files were produced.

1990 Self-Administered Questionnaire (90SAQ)

Each 1990 Head and Wife/"Wife" age 50 or older was mailed a self- administered questionnaire. The PSID had 3,276 core sample Heads and Wives/"Wives" in 1990 who were age 50 or older. We received 2,429 codeable questionnaires for a response rate of 74.4%. The data file has one record per responding person.

The questions asked about the respondent's health, health care coverage, long term care coverage, and asked permission for the PSID to obtain Medicare claims information from the Health Care Financing Administration.

The ZIP file contains an ASCII data file, associated SAS and SPSS data definition statements, an OSIRIS dictionary and a documentation file in WordPerfect format.



1990 Telephone Health Care Cost Questionnaire (90THQ)

The 1990 telephone health questionnaire for Heads and Wives/"Wives" age 65 or older was administered by the interviewer at the time of the main interview and was returned along with the main questionnaire. The PSID sample for 1990 included 1,194 core families with Heads and/ or Wives/"Wives" who were age 65 or older. Of these 1,194 eligible families, we failed to obtain the supplement for only 16 of them; thus the total number of families receiving the supplement was 1,178. The data file has one record per eligible family.

The questions in this supplement covered detailed health care costs for eligible Heads and Wives/"Wives". The data include separate cost and payment source information associated with every hospitalization or nursing home stay for each age-eligible Head or Wife/"Wife" during the twelve months prior to the 1990 interview. Similar cost and payment data about outpatient surgery, other office visits, oral surgery, prescription medication, eyeglasses and hearing aids, and professional and nonprofessional home care were also collected for each eligible Head and/or Wife/"Wife". Some collective questions were included about help with domestic duties, both paid and unpaid; help with financial planning; and cash and non-cash gifts.

The ZIP file contains an ASCII data file, associated SAS and SPSS data definition statements, an OSIRIS dictionary and a documentation file in ASCII format with page breaks.
