With the street information provided in GeoTAX, you may request an address level latitude/longitude coordinate return. For ZIP+4 and ZIP-level data, the latitude/longitude pairs returned by GeoTAX reflect the center of population of the ZIP or ZIP+4 Code. For block groups and census tracts, the centers are determined based on area rather than population. For example, the population center of the rural block group in the figure is well south of what would be considered the area center. This would indicate that the most populated region of this area is in the southwest corner (most likely because of the nearby town of Hapsburg). This distinction is significant for distance calculations, especially in rural areas where the geographic areas are much larger.

Note: No latitude/longitude coordinate are returned if the input ZIP Code does not appear on any of the database files.
