How can I find coordinates (Latitude and Longitude) for ZCTAs based on centroid?
The downloadable ZCTA gazetteer files contain the latitude/longitude coordinates for each Census 2000 ZCTA. Coordinates for ZCTA internal points (calculated by considering the latitude/longitude of all bounding features and then creating an area-weighted average point inside the polygon) are also available in the TIGER/LineĀ® Files.
