The Population and Ecology Research Laboratory (PERL) has collected a wide range of social science data regarding social change, social life, families, and the environment in Nepal. The measurements themselves included survey data collection, ethnographic data collection, mixed-method data collection, botanical counts, land use measures, and geographic information system data collection. All these data are from Western Chitwan Valley. Data was collected at the neighborhood, household, individual, and environmental levels.
These data are available through the Inter-University Consortium for Political and Social Research.
