Getting null from ACS block-group query

For ACS data - is there a way to tell which codes are valid for tracts vs block group?

Some codes work for both, some return "null" when the block-group level is queried.

For example, the following url works for the tract level:

http://api.census.gov/data/2010/acs5?key=4be82289939444f20513cd7c3c3eafb42e0d9ccf&get=B06007_003E,NAME&for=tract:*&in=state:08+county:059

But using the same code, it returns null for the block-group level:

http://api.census.gov/data/2010/acs5?key=4be82289939444f20513cd7c3c3eafb42e0d9ccf&get=B06007_003E,NAME&for=block%20group:*&in=state:08+county:059+tract:012035

Thanks in advanced!

  1. Elizabeth,

    Please see the ACS release documentation here: http://www.census.gov/acs/www/data_documentation/2010_release/

    On that page there is a link for "ACS 5-yr detailed tables". That spreadsheet will tell you what variables are available at the block group level.

    1. I think it was mentioned before, but it would be very helpful if this information was available as an attribute in the <concept> tag in the XML file.
