Brian,
Tell me something. Do you want to use these data for *individual* block
groups or do you want to aggregate BGs to larger areas, such as TAZs? I
hope you know that the sampling errors for single BG data are so high as to
render the data absolutely useless. I think that's why you can't find the
numbers.

Hello,****

Brian Chenault from the Hampton Roads Transportation Planning Organization
here. We are trying to collect several pieces of data at the *block group
* level using 2007-2011 ACS 5-year estimates. Using the Census’ Summary
File Excel Retrieval Tool, we are able to retrieve basic population data at
the block group level. However, data at the block group level is not
provided for poverty, language spoken at home, etc. This appeared to be
the case even when examining 2006-2010/2005-2009 5-year estimates. Has
this information not been “filtered down” from the census tract level yet?
How is one supposed to go about gathering this type of *updated*information at the
*block group level*?****

Much appreciated,****
