I'm having some challenges with downloading data.
I have the summary files in SQL databases if you want to work with it that way. there is always NHGIS.org as well.
Thanks so much for the generosity and tip JamiRae, i may be in touch and will check out NHGIS.org!
yes nhghis will definitely get you the block groups
Indeed, this and social explorer are terrific resources! Thank you to all you folks who helped me with this question!
