Finding Geographies

I'm still a newbie and am trying to find a way to pull geographies via the API.

 

For example, is there a way for our application to only store state names or FIPS codes, then pull all other possible geographies via the API? Or, do we need to store all the needed geographies on our end?

Using Data

Best practice for census tract level GeoID

I am trying to make tract-level thematic maps for several indicators (e.g. unemployment, median family income etc.). In the KML and SVG files I am using (including that obtained from TIGER) the 11 digit GeoID10 seems to be the best column through which I can merge data pertaining to the census tracts either by using the "GEO.id2" field from ACS data downloaded as CSV from FactFinder or through a concatenation of ...more »

Application Ideas

Interactive Hierarchy of Census Geographic Entities

The general population is familiar with ZIP codes, county and state boundaries. However, the Census also offers statistics in other useful geographies (e.g., NECTA, County Subdivisin, Tract, etc). But, understanding the hierarchy of Census geographic entities is not intuitive. The Census produced a diagram explaining the levels geography (http://www.census.gov/geo/reference/pdfs/geodiagram.pdf) but more can be done. ...more »

API Technical Discussions

geographic boundaries

First of all I want to thank you all at the Census for your brilliant effort in providing a usable API. I think the documentation needs to be improved, though, with more examples of string requests and possible use of wild cards, if any. I am currently working on a web application where I want the user to visualize demographic indicators within a certain distance from a specific/user-picked LatLong (for instance total ...more »
