Blocks and block groups?

[palewire]

I think they're possible, but I'm not sure what parent area you'd have to iterate thru to pull them piece by piece. The MOE is probably gnarly in the ACS too, no? Might be a good area to explore, especially if we aim to add support for 2010 sf1 in addition to the acs5.

Belatedly...

You can get them by state, under the decennial census. So that would most likely mean adding support for 2010 SF1.

For blocks, though, I'm not sure the Census API is easier than the FTP site and a makefile. I ended up generating a text file with URLs and running wget -I urls.txt on it to download blocks from every state. As far as I can tell, blocks only have data on population and number of households, so maybe not worth adding here.

I'll dig into block groups more and report back.
