National Fertility Survey, 1975 (ICPSR 4334)
National Survey of Families and Households, Wave 1: 1987-1988, [United States] (ICPSR 6041)
The National Survey of Families and Households (NSFH), Wave 1 (1987-1988) is the first of three waves in a longitudinal survey that was designed to study the causes and consequences of changes happening in families and households within the United States. At a time when the range of family structures was becoming more and more diverse, this study permitted a close examination of the resulting family compositions and household operations. One adult per household was randomly selected as the primary respondent, and there was a total of 13,007 respondents. In addition to the main interview conducted with the primary respondent, a shorter, self-administered questionnaire was given to the spouse or cohabitating partner, and also administered to the householder if he or she was a relative of the primary respondent.
A considerable amount of life-history information was collected, such as the respondent's family living arrangements in childhood, departures and returns to the parental home, and histories of marriage, separation, divorce, cohabitation, adoption, child custody arrangements, and stepfamily relations. Respondents were also asked about the relationship of household members to each other and the quality of their relationships with their parents, children, and in-laws. Information on economic well-being was also collected, including earnings from wages, self-employment income, interest, dividends, investments, pensions, Social Security, public assistance, and child support/alimony. Demographic information collected includes sex, age, marital status, education, and employment.
National Survey of Families and Households, Wave 2: 1992-1994, [United States] (ICPSR 6906)
The National Survey of Families and Households (NSFH), Wave 2 1992-1994, a longitudinal population-based survey of families and households in the United States, investigates the causes and consequences of changes in American family and household structure. This is the second wave of a three part survey. The current study, NSFH Wave 2, is the second follow up and was conducted in 1992-1994. The sample included all NSFH Wave 1 main respondents and spouse/partner with focal children and all other NSFH Wave 1 main respondents ages 45 and over in 2000, as well as their NSFH Wave 1 spouse/partner.
The Wave 2 survey included the following components: (1) an interview of all surviving members of the original sample via face-to-face personal interview, (2) a personal interview with the current spouse or cohabiting partner almost identical to the interview with the main respondent, (3) a personal interview with the original spouse or partner of the primary respondent in cases where this relationship had ended, (4) a telephone interview with "focal children" who were originally aged 13-18 in Wave 1, (5) a short telephone interview with "focal children" who were originally aged 5-12 in Wave 1, (6) short proxy interviews with a surviving spouse or other relative in cases where the original respondent had died or was too ill to interview, and (7) a telephone interview with a randomly-selected parent of the main respondent. Demographic information collected includes sex, age, marital status, education, and employment

The National Survey of Family Growth (NSFG) gathers information on pregnancy and births, marriage and cohabitation, infertility, use of contraception, family life, and general and reproductive health. The survey sample is designed to produce national data, not estimates for individual states. Beginning in 1973, NSFG was designed to be nationally representative of ever-married women 15-44 years of age in the civilian, non-institutionalized population of the United States (household population). Later sample changes to NSFG include:
- Interviewing women aged 15-44 regardless of marital experience (1982)
- Interviewing an independent sample of men aged 15-44 (2002)
- Expanding the age range for women and men to 15-49 (2015)
- Grandparent-Parent-Adult Child triplets: ~1,400
For the 2011-2019 continuous interviewing period, four sets of 2-year public-use data files were released:
- 2011-2013 NSFG: 10,416 respondents aged 15-44 (5,601 women and 4,815 men)
- 2013-2015 NSFG: 10,205 respondents aged 15-44 (5,699 women and 4,506 men)
- 2015-2017 NSFG: 10,094 respondents aged 15-49 (5,554 women and 4,540 men)
- 2017-2019 NSFG: 11,347 respondents aged 15-49 (6,141 women and 5,206 men)
