Summary View help for Summary
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. For additional information regarding the Chitwan Valley Family Study, please visit the Chitwan Valley Family Study Website.
** IMPORTANT NOTE FOR STATA USERS **
The Stata files for datasets 7, 15, 16, 18, 32, 34, 35, and 38 were produced in Stata 13. Users of earlier versions of Stata will not be able to read them.
There are a few options for users of Stata 12 or earlier to work around the compatibility issue:
- Upgrade to Stata 13
- Find a computer with Stata 13 and use the 'saveold' command to create a Version 12 file
- Use the latest version of a file conversion utility, such as Stat/Transfer (older versions cannot read Stata 13 files)

Study Purpose View help for Study Purpose
The study was designed to investigate the influence of changing social contexts on family formation behaviors, marriage, childbearing, and contraceptive use. The research investigates the extent to which changes in the community produce changes in family formation behavior, and whether the family organization of individual life courses produces these changes in behavior.
Study Design View help for Study Design
The study used a combination of ethnographic and survey research methods to gather 171 neighborhood histories, 142 school histories, 118 health service histories, 20 bus route histories, household farming practices, family planning histories, and household composition in Western Chitwan, Nepal.
Sample View help for Sample
Neighborhoods were chosen as the sampling units. The sample is stratified into three distance strata. Stratum 1 includes only areas near the urban center, city of Narayanghat. Stratum 3 includes only areas far from Narayanghat and Stratum 2 includes the areas at the middle, between Stratum 1 and Stratum 3. The sample is two stage. Stage 1 is a sample of settlements selected using 1991 census data as a sampling frame. The settlement ranged from 15 to 1,000 households. Measure of size was the number of female residents in the settlement. Stage 1 sampling yielded a systematic sample of 10 settlements in each stratum, for a total of 30 settlements. Stage 2 was the actual sample of Toles, or neighborhoods. Stage 2 sampling units are neighborhoods which are defined as clusters of approximately 5 to 15 households in close proximity to one another.

Description of Variables View help for Description of Variables
Personal histories were gathered from the 5,271 individuals ages 15-59 years living in these neighborhoods using a semi-structured Life History Calendar and a highly structured survey questionnaire. The sample neighborhoods for this study were chosen to represent the five major ethnic groups inhabiting the area: high caste Hindus, hill Tibeto-Burmese (such as Gurung, Tamang, and Magar), indigenous terai Tibeto-Burmese (such as Tharu, Darai, and Kumal), Newar, and other caste Hindus. Neighborhood history calendars measured the neighborhood's distance, in terms of minutes walking, to a variety of organizations and services. Schools were defined as places of instruction for children of any age or grade. Health clinics were defined as any places of care and healing, such as doctors' offices, hospitals, and health posts. Employers were any places that employed 10 or more people for pay. Cinemas were movie theaters or halls where movies were shown. Bus stops were any places where people could obtain a ride for pay on a vehicle.
