The Chitwan Valley Family Study (CVFS) is a comprehensive family panel study of individuals, households, and communities in the Chitwan Valley of Nepal. The study was initially designed to investigate the influence of changing community and household contexts on population outcomes such as marital and childbearing processes. Over time, the goals of the study expanded to investigate family dynamics, intergenerational influences, child health, migration, labor force participation, attitudes and beliefs, mental health, agricultural production, environmental change, and many other topics. The data include full life histories for more than 10,000 individuals, tracking and interviews with all migrants, continuous measurement of community change, over 25 years of demographic event registry, and many other data collections.

The Relationship Dynamics and Social Life (RDSL) Study aims to investigate the types of romantic relationships that produce early and/or unintended pregnancies. The study is based on a representative sample of 1,003 women aged 18 to 22 residing in Genesee County, Michigan. The research team focused on women ages 18 to 22 because these ages are characterized by the highest rates of unintended pregnancy, as well as significant instability and change in the dynamic determinants of unintended pregnancy.

Data collection for the baseline survey was conducted March 2008 through July 2009, and consisted of a 60-minute face-to-face interview to gather information on respondent attitudes and behaviors, intimate and familial relationships, contraceptive use, reproductive history, self-reported height and weight, and socio-demographic characteristics.

The baseline survey was followed by a series of three supplemental surveys administered over a two-and-a-half year period between May 2009 and August 2011. These surveys covered a wide range of topics, including family living arrangements, socioeconomic status, employment, media consumption, mental health, violence, personality traits, assumptions and knowledge regarding various forms of contraception, and attitudes and opinions about social life. The second major component of the RDSL features journal data collected concurrently with the supplemental surveys. The focus of the journal data collection was to gather dynamic, prospective measurements of pregnancy desires and contraceptive use, as well as relationship attributes such as commitment, sexual intimacy, and decision-making regarding contraception.

Demographic information collected includes respondent age, race, ethnicity, religious affiliation, marital status, education, employment status, income, and household size and composition.
