I just downloaded block-level census data, using this answer Where to get 2010 Census Block data?

It output a spreadsheet with a bunch of rows of the format

GEO.id                   | GEO.id2    | Geo.display-label
1000000US22071000100100  | 2.2071E+14 | Block 1002, Block Group 1, Census Tract 1, Orleans Parish, Louisiana

I want to convert "Block 1002, Block Group 1, Census Tract 1" to something like 700 Block of Jefferson St. Etc.

How do I convert these "addresses" into street addresses or longitudes/latitudes?


I can go individually from street address to census block using the advanced search on American Fact Finder, but I am looking for a way to do a batch conversion.

The FCC has an API that will do block conversions from lat/longitude to blocks: http://www.fcc.gov/developers/census-block-conversions-api

    Didn't you download the features along with the data? The answers to the thread you reference describe how to do that. The Census site itself gives plenty of instruction, too.

  • @whuber I did download the features but am not sure what to make of them. I don't know very much about the census. Can you link to the instructions?

    Displaying features is the most basic operation in GIS, so consider running the tutorial for your GIS software. You can also search our site for related ideas.

  • @whuber for sure. I am just learning how to do all this. When you say "The Census site itself gives plenty of instruction" can you point me where to look?

  • Wait a minute, do you mean FROM street address TO Census Block? As in enter a street address and return a Census Block ID as the result? Because that would make a lot more sense.

If these are polygons, you can use the feature to point tool in ArcGIS. Then use calculate geometry within the attribute table to create X and Y tables.
