Description

The number of incident leukemia cases from 1978-1982 per census tract for an 8-county region of upstate New York.

This is the same data as in nydf in a different format.

Note that the coordinates in the polygons have been projected to a different coordinate system (UTM, zone 18) compared to nydf, but the order of the regions/polygons is the same as in nydf.
