Why was Montgomery County selected as a Study location?
Families who participate in the National Children’s Study will come from 105 national Study locations (counties or groups of counties) across the United States. All locations were selected using a probability-based sampling method to make sure that children and families across the nation—from diverse ethnic, racial, economic, religious, geographic, and social groups—are represented in the Study. This strategy was chosen based on the input from a national panel of experts and reviewed by working groups and the National Children’s Study Federal Advisory Committee. The Study locations selected include 79 metropolitan areas (urban, suburban, and small cities), as well as 26 rural communities.
