Biodemographic Models of Reproductive Aging (BIMORA) Project, 1998-2002 [United States] (ICPSR 4452)
Explaining Low Fertility in Italy (ELFI) (ICPSR 31881)
The ethnographic fieldwork portion of the project - interviews with women of reproductive age, and when available their partners and mothers - was initiated and completed in 2006. For each of four Italian cities (Padua, Bologna, Cagliari, and Naples) studied ethnographically by trained anthropologists, both a working-class and a middle-class neighborhood were identified. These interviews (349 in number) have been transcribed without identifiers. All interviews have been coded and assigned 'attributes' (or nominative variables, such as gender, civil/religious status of marriage, etc.) using the qualitative data analysis software (NVIVO), and these reside in secure electronic project folders. This large body of qualitative interview data is now complete and ready for use across the international collaborative units. Preliminary research reveals the particular significance of family ties in Italy, the fundamental role played by gender systems, and the specific cultural, socio-economic, and politic contexts in which fertility behavior and parenting are embedded.
First Baby Study (FBS), Pennsylvania, 2009-2014 (ICPSR 38778)
The First Baby Study (FBS) was a prospective cohort study designed to investigate the association between mode of delivery at first childbirth (cesarean or vaginal) and subsequent fecundity and fertility over the course of a 3-year follow-up period. Women were enrolled during pregnancy and interviewed by telephone in their third trimester. Enrolled participants were followed-up with and surveyed at 1, 6, 12, 18, 24, 30 and 36 months postpartum. Participants were enrolled in 2009 to 2011 and the last interview was conducted in 2014.

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)
