Access Micro-data for Blocks

I'm working on a school project with 2010 Census data.

 

Currently, we are getting tract-level data using codes from http://api.census.gov/data/2010/sf1/variables.json to get data.

 

For example, to find the white 65-year old males in a county's tracts, we make the API call:

http://api.census.gov/data/2010/sf1?key=[key]&get=PCT012I068,NAME&for=tract:*&in=state:08+county:059

 

However, when making the same call at a block level, the file is empty. See:

http://api.census.gov/data/2010/sf1?key=[key]&get=PCT012I068,NAME&for=block:*&in=state:08+county:059+tract:012035

 

We assume this is because the 2010 variables we are currently using are pre-aggregated data. It would be infeasible to compile this data for all the blocks.

 

How do we get access to the micro-data to get results at the block level (ex: white male 65-year-olds per block)?
