  1. Notes: Based on 2000 US Census Data STF 3. Education: Total Males and Females 18 years or older. 1999 Median Income in Florida was $41,994 dollars (US Census, 2000). Centroid containment method contained only those census tracts that had a geographic center within one-mile of an NPL. If the one-mile radius did not include the centroid of the host tract, it was not included. Occupation; % of White collar includes P50, % of Blue collar includes p50 (includes food service). Percentages differ because they do not include service protection services which could be considered white or blue collar.
