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:,NAME&for=tract:*&in=state:08+county:059


But using the same code, it returns null for the block-group level:,NAME&for=block%20group:*&in=state:08+county:059+tract:012035


Thanks in advanced!
