Calendar Methods Study
Childhood Health Calendar
Those respondents who indicated having at least one of certain childhood health conditions (variables H32-H45),
or that their spouse had had at least one of the conditions, were asked to respond to the health calendar sequence.
The calendar variables (naming convention: "[event]EHC_nn", where 'nn' is a sequential number or 'AgeGR17') record
whether they had the condition at each age, zero through 16 and 17+, and also how old they were if 17+. These
variables were combined into a sequential character string (naming convention: "[event]EHC") for each health condition,
with age appended at the end of the character string (separated by a dash): e.g., the first-digit in the character
string is the response for age-0, the second-digit in the character string is the response for age-1, and so forth.
SAS data and documentation are available in the following:
Corrected Interview Date Files: 1993, 1994
For the 1993 and 1994 wave of data collection, the PSID began using electronic interviewing
for the first time. Due to system crashes, a number of interviews were conducted
using paper and pencil and were entered by coding staff into the interviewing
application, and hence the Survey Research Center's sample management systems logged
the entry date as the interview completion date.

Marriage History File: 1985-2005
The 1985-2005 Marriage History File is specifically designed to
facilitate access to detailed information collected in the 1985
through 2005 waves of the Panel Study of Income Dynamics (PSID) regarding
retrospective histories of marriages.
This file contains detailed information about marriages of people of
marriage-eligible ages living in a PSID family at the time of the interview in
any wave between 1985 and 2005. Each record contains all past-year and
most-recent-year detail about the timing and circumstances of a marriage for a
specified individual up to and including 2003 (or whichever wave 1985-2003
when the individual was last in an interviewed family unit). Data on this file
are structured in an one-record-per-marriage format, with each record
containing relevant data about the spouse and timing of a specific marriage. In
situations where an individual has never been married, there is one record
recording the fact that the individual has no marriages. Records on this file
are short and contain only relevant identifiers for the individual and his/her
spouse and detailed information about each marriage. Variables on this file
include the identifiers for each individual and his/her spouse, month and year
of marriages/divorce/widowhood, order of the specific marriage, total number of
marriages and the most recent year wave when data were collected.
For data users who only want some of the detail of the marriage data,
information on marriage history is presented in a more summarized form on the
PSID Individual file in several individual- level summary variables. These
variables include number of marriages, beginning and end month and year for the
first and the most recent marriages, marital status of the individual at the
time of the most recent interview, and the most recent wave when marriage data
were collected.

Childbirth and Adoption History File: 1985-2005
The Childbirth and Adoption History File is specifically designed to facilitate
access to detailed information collected in the 1985 through 2005 waves of
the Panel Study of Income Dynamics (PSID) regarding retrospective histories of
childbirth and adoption.
This file contains detailed information about who was living with a PSID family
at the time of the interview in any wave 1985-2005 and his/her biological or
adopted children. Each record contains all present-year and past-year detail
about the timing and circumstances of childbirth and adoption experience for an
individual up to and including 2005. In situations where an individual has
never had or adopted any children, there is one record recording the fact that
the individual has no such experience. Records in this file are short and
contain only relevant identifiers for the individual and his/her children and
month and year of childbirth or adoption events. Variables on this file include
the identifiers for each parent and child, month and year of birth for both
parent and child, birth order, birth weight and date of death for a child, year
of most recent report and number of births/adoptions, etc. Data on this file
are structured in a one-record-per-event format, with each record representing
a specific childbirth or adoption event.
For data users who only want some of the detail on childbirth data, information
on childbirth and adoption histories is presented in a more summarized form in
several family-level and individual-level summary variables on the 1999,
2001, 2003, and 2005 Family Files and the 1968-2005 Individual File, respectively. These
variables include number of childbirth, birth month and year of most children,
identifiers of mother and of father, whether the mother was married at the time
the individual was born, and birth order of individual.

since the 1983 wave of the Panel Study of Income Dynamics (PSID) about
parent-child relationships. This file consists of identifier variables that
link children with their parents.
The data records are short. They contain relevant identifiers for the child, his
or her birth and adoptive parents, and information source indicators. The file
is intended to be used to facilitate linking children's and parents' data
records from the 1968-2005 Individual File. Linkages can be done from either
the child's or a parent's standpoint.

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.

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.

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.

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.

Telephone Health and Self Administered Questionnaire Supplements: 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.

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.

Time and Money Transfer File: 1988
The 1988 Time and Money Transfer File is designed to facilitate access to the
detailed information collected in the 1988 Wave of the Panel Study of Income
Dynamics (PSID) regarding transfers, in the form of time and money, between a
PSID family unit and other persons during the 1987 calendar year. The main PSID
1988 Family File contains summary information about these transfers but this
Time and Money Transfers File provides the complete set of details collected
about them. Each record in this file represents a separate report of a transfer
flow.
This 1988 supplement has two related major focuses: (1) transfers involving PSID
Head's and Wife's/"Wife's" parents and (2) inter-family transfers with someone
other than parents. Information about four basic types of transfer flows -- 1)
money given, 2) money received, 3) time help given and 4) time help received --
is recorded.

Wealth Transfer
In 2007, a series of questions was added to the PSID on inheritances and bequests. This module was asked in the 2007 wave only.
The questions are supported by a subproject award to Frank Stafford, James Heckman, and John Laitner as part of a Program Project (P01) grant awarded by the National Institute on Aging to Robert F. Schoeni.
A central mission of this P01 was to solicit rapid feedback from the user community to the PSID investigators on data quality and future data collection needs. Thus, these data are being released for this purpose, in advance of the release of the PSID 2007 data which is scheduled for December 2008. As a result, these data are completely raw and have not been processed or cleaned in any way. User support is not available for these data, but staff are interested in user feedback about their quality (psidhelp@umich.edu). Once the 2007 main PSID data are released, these data will be removed from the website.
