Census Download Toolbox for ArcGIS

A Python Toolbox for ArcGIS Desktop to make quick retrieval of Census information.

Census API Key

In order for the toolbox to work properly, the CensusDownload.pyt Python Toolbox must be updated with a valid Census API key.

A Census API key can be requested from the Census API key request page. You must modify the CensusDownload.pyt file to include your API key. You must also make sure to activate your key before use.

Download By Extent

Within the Census Download - By Extent tool, a user can specify an area of interest (such as the current map extent) and download Census tracts, block groups, and/or blocks, along with associated Census data. When run from ArcMap, the Census Download tool will reproject the specified extent as necessary, provided the primary data frame in ArcMap has a projection/coordinate system defined.
