Ecologic Surveillance
The analysis and monitoring of health and disease outcomes for various communities
and population subgroups by important social, economic, and environmental
characteristics is known as ecologic surveillance. For cancer, community-level data
obtained from the census and other population data sources (containing area-based social,
demographic, behavioral, and environmental data) are used to provide insight into
rates and trends, particularly with regard to a possible differential impact of
cancer control interventions by socioeconomic factors and urbanization.
In the SEER Program, NCI researchers have used detailed census data on education,
income, housing, and transportation, to develop a comprehensive area-based index of
socioeconomic status for the United States at the census tract and county levels.
These data have been linked to the national mortality data and the SEER cancer incidence data.
Using this area index, changing socioeconomic patterns are examined in overall cancer
mortality and in lung and colorectal cancer mortality among U.S. men and women
from 1950 to 1998. Two recently published papers include:
