Campaign: Using Data

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!
