National Survey of Family Growth (NSFG), Cycle III (Women Aged 15-19), 1982

Investigators: National Center for Health Statistics

Cycle III of the National Survey of Family Growth (NSFG) was designed as a nationally representative sample of all women aged 15 to 44 in the non-institutional population of the conterminous United States. Earlier cycles of NSFG had excluded never married, childless women; in contrast, Cycle III included all women of childbearing years regardless of marital status. Questionnaires for the survey contained questions on sex education, respondent's pregnancy history, menarche and sexual experience, contraceptive history, sterility and subfecundity, birth expectations, visits for family planning services, and background and work history.

National Survey of Family Growth, Cycle 5, 1995 (NSFG)

Investigators: National Center for Health Statistics

The National Survey of Family Growth, Cycle 5, 1995 (NSFG) is the fifth in a series of periodic surveys of women 15-44 years of age. Previous surveys were conducted in 1973, 1976, 1982, and 1988 with a telephone reinterview of the 1988 respondents in 1990. Topics covered in previous interviews included the month and year of first intercourse; pregnancy, contraceptive, marital, and cohabitation histories, employment and occupation, child care, fecundity and sterility, prenatal medical care, family planning services, birth expectations, ethnicity, education, religion, and income. For Cycle 5, event histories of education, living arrangements during childhood, and work have been added, along with complete marital and cohabitation histories, and sexual partner histories for 5 years prior to the interview. The survey also included, for the first time in 1995, characteristics of male partners, new items on consistency of contraceptive use, new questions on pregnancy wantedness, and a computer-assisted self- administered section containing questions on sensitive topics such as abortion and forced intercourse. The overall objective of the NSFG is to supplement the vital statistics of fertility and of family formation and dissolution, with more detailed data on the "intermediate variables" which shape these trends and on the health and socioeconomic contexts in which they occur. The uses of the data gathered in the NSFG are broad, though mostly in the health and demographic fields. The 1995 NSFG obtained detailed information on factors affecting childbearing from a national probability sample of 10,847 women 15 to 44 years of age. The 1995 NSFG data are divided into two files. The respondent file (Data Set N8-O4) contains most of the information from the Cycle 5 instrument (see below) using the individual respondent as the unit of analysis. This data set contains 5,711 variables for 10,847 cases. The Interval file (Data Set O5) uses the pregnancy as the unit of analysis and contains data for each pregnancy (regardless of the result) for all of the respondents. Several related variables from the respondent file are included as well. This data set includes 21,332 cases.

National Survey of Family Growth, Cycle 6, 2002

Investigators: National Center for Health Statistics

The National Survey of Family Growth (NSFG), Cycle 6, 2002 was conducted by the National Center for Health Statistics (NCHS). Cycle 6 was based on a national multi-stage probability sample designed to represent the civilian noninstitutionalized population of the United States, 15-44 years of age. Interviewing for the NSFG was conducted from January 2002 to March 2003 by the University of Michigan’s Institute for Social Research under contract with NCHS. In-person interviews were completed with 7,643 females 15-44 years of age and with 4,928 males 15-44 years of age. The sample of females and the sample of males are independent samples consisting of unrelated and unacquainted people. The purpose of the survey is to produce national estimates of: factors affecting pregnancy – including sexual activity, contraceptive use, infertility, and sources of family planning services; factors affecting marriage, divorce, cohabitation, and adoption; what men and women do to raise their children; and men’s and women’s attitudes about sex, childbearing, and marriage. The data from the NSFG are used by NCHS and other agencies as the basis for reports and studies on fertility, marriage and cohabitation, contraception, and related issues. The 2002 NSFG data are divided into three files. The Female Respondent File (Data Set R4-R7) contains most of the information from the Cycle 6 female questionnaire and uses the individual respondent as the unit of analysis. This data set contains 3,087 variables for 7,643 cases. The Female Pregnancy File (Data Set R8) uses the pregnancy as the unit of analysis and contains data for each pregnancy (regardless of the result) for all of the respondents. Several related variables from the respondent file are included as well. This data set includes 243 variables for 13,593 cases. The Male Respondent File (Data Set R9-S1) contains most of the information from the Cycle 6 male questionnaire and uses the individual male respondent as the unit of analysis. This data set contains 1,993 variables for 4,928 males.

National Survey of Family Growth, Cycle III Exposure Interval File, 1982

Investigators: William Grady

The purpose of this extracted data file was to create an Exposure Interval File compatible with an analysis of contraceptive failure, using data from Cycle III of the National Survey of Family Growth (NSFG). NSFG data were originally collected by the National Center for Health Statistics; information on the original survey can be found in the NCHS documentation for Cycle III Public Use Sample Data Tape, or in the User's Guide for Data Set 26 prepared by the Data Archive on Adolescent Pregnancy and Pregnancy Prevention (DAAPPP). In all, the 7,969 respondents to the NSFG contributed 11,253 separate, cotinuous intervals of exposure that met the criteria described above. Continuous intervals separated by changes in marital status and/or by periods of no intercourse were coded as multiple intervals, yielding 12,962 intervals available for analysis. For each of these 12,962 intervals, 34 interval-related characteristics are available from this data file.

National Survey of Family Growth, Cycle IV, 1988

Investigators: National Center for Health Statistics

The National Survey of Family Growth (NSFG), Cycle IV, 1988 queries 8,450 women 15-44 years of age of all marital statuses. The DAAPPP file consists of a "respondent" or "woman" record which contains all available NSFG information about the woman herself plus a significant extract of the NSFG pregnancy history file: information from up to five (the first four and the last) of her pregnancies. Topics covered in the interview include: the month and year of first intercourse; pregnancy, contraceptive, and marital and cohabitation histories; employment and occupation; child care; fecundity and sterility; prenatal medical care; family planning services; birth expectations; ethnicity; education; religion; and income.

National Survey of Family Growth, Cycle IV, 1988 and 1990, Telephone Reinterview

Investigators: National Center for Health Statistics

The National Survey of Family Growth (NSFG), Cycle IV, 1988 & 1990 Telephone Reinterview is the fourth in a series of periodic studies of women 15-44 years of age. Topics include timing of first intercourse; pregnancy, contraceptive, marital, and cohabitation histories; employment and occupation; child care, fecundity, and sterility; wantedness of pregnancies; adoption; prenatal medical care; family planning services; birth expectations; AIDS and HIV knowledge; ethnicity; religion; and income. This data set contains merged data for the survey conducted at two separate points in time: 1988 when 8,450 respondents were interviewed in person and 1990 when 5,686 respondents (5,359 of whom participated in the 1988 survey, and 327 first-time teen respondents) were interviewed by telephone. To simplify longitudinal analyses, data from the 1988 NSFG Cycle IV and the 1990 Telephone Reinterview were then merged using respondent ID to create a single rectangular data file that contains both waves of data collection. The combined 1988 and 1990 NSFG contains data from 8,777 respondents and 3,462 variables (2,430 assessed in 1988 and 1,032 assessed in 1990).

National Survey of Family Growth, Cycle V, 1995

Investigators: National Center for Health Statistics

This is the fifth in a series of periodic surveys of women 15-44 years of age. Previous surveys were conducted in 1973, 1976, 1982, and 1988 with a telephone reinterview of the 1988 respondents in 1990. Topics covered in previous interviews included the month and year of first intercourse; pregnancy, contraceptive, marital, and cohabitation histories, employment and occupation, child care, fecundity and sterility, prenatal medical care, family planning services, birth expectations, ethnicity, education, religion, and income. For Cycle 5, event histories of education, living arrangements during childhood, and work have been added, along with complete marital and cohabitation histories, and sexual partner histories for 5 years prior to the interview. The survey also included, for the first time in 1995, characteristics of male partners, new items on consistency of contraceptive use, new questions on pregnancy wantedness, and a computer-assisted selfadministered section containing questions on sensitive topics such as abortion and forced intercourse.

The uses of the data gathered in the NSFG are broad, though mostly in the health and demographic fields. The 1995 NSFG obtained detailed information on factors affecting childbearing from a national probability sample of women 15 to 44 years of age. The purpose of the survey is to produce national estimates and an information base on factors affecting pregnancy including sexual activity, contraceptive use, infertility, and sources of family planning services and the health of women and infants. For Cycle 5, interviewing and data processing were conducted by the Research Triangle Institute, under a contract with NCHS.

National Survey of Men, 1991

Investigators: Koray Tanfer

The 1991 National Survey of Men (NSM-I) was conducted between March 1991 and January 1992, under a grant from the National Institute of Child Health and Human Development, to examine issues related to sexual behavior and condom use among a national household probability sample of males aged 20-39. The NSM-I was intended to serve as the baseline survey for a longitudinal study of this group of U.S. men. Data collection and processing were carried out by the Institute for Survey Research at Temple University in Philadelphia. In-person interviews were conducted using a standard questionnaire with 3,321 eligible males. The survey questionnaire assessed information regarding respondents' personal background; sexual initiation and current exposure; current wife or partner; previous marital relationships; non-marital sexual partners; nonsexual romantic partners; health and risktaking behavior; attitudes, perceptions and knowledge regarding health and contraception; and condom use. A self-administered questionnaire, which assessed self-esteem, locus of control, and attitudes toward marriage, was also completed by respondents.
