About the Data

This unique research tool contained more than 80 in-depth, high-quality datasets that primarily covered the 1990s but also covered several previous decades. Breast cancer is a disease of long latency, and data from years ago are especially useful to researchers.

The LI GIS incorporated:

  • Topographic data, including locations of roads, water features, parks and landmarks, and base maps which define legal boundaries and serve as reference points
  • Demographic data, including the age, race, sex, and income of the population
  • Health outcome data, including relative breast cancer incidence and health facilities data
  • Environmental data, including land use and cover; railroads; traffic; water use and potential sources of water pollution; chemical releases into water, air, and soil; electrical power lines; information on toxic chemicals and hazardous and municipal waste; and radiation
  • Weather information and satellite image maps
  • Data also are included with less detail and geographic precision for areas within 31 miles from the two counties, and very limited data are included for areas within a 100-mile radius from the midpoint of the boundary line between the two counties. The extended area includes counties in Connecticut, New Jersey, New York, Pennsylvania, Rhode Island, and Massachusetts.
