Why do some zip codes appear, while others do not?
Zip code boundaries change from year to year. Changes include new, consolidated, and removed zip codes and occur more frequently than indicator data is collected and reported. Therefore HCI must select Zip Code boundary files that most closely match the geographies for which we have data.

My Indicator has a map tag, but I cannot see a map.
A map is missing only when a site maintains indicator data at a geography that is NOT included in our map boundary file. Example: data for Zip Code 12345 is from 2010, and Zip Code 12345 no longer exists as of 2012, the year of HCI's zip code boundary file. Therefore the map for this zip code cannot be displayed.

Why can't I see my custom service area?
HCI maps are designed to map standard geographies (county, zip code, and census tract) and in most cases will not display a custom area.

Why is the indicator data year for one location different from the others?
HCI will occasionally suppress values due to instability of the reported data. Consequently, values shown at other locations on the map may be from different measurement periods than the one shown on this page. Example: Zip Code 1 and Zip Code 2 both have 2010 data for the same indicator, but the data for Zip Code 2 is unstable. Our system will show 2010 data for Zip Code 1, and suppress the 2010 data for Zip Code 2, instead showing the most currently available, stable data.
