Census tracts are listed first. Where you see a census tract with a hyphen, the number after the hyphen is the block group number. Blocks are listed for purposes of validating data, but the actual data comes from estimates, as blocks do not include data at the level of detail needed.
25-2 blocks 2014-2020 (about 1/4 of the block group) 25-3 26-2 blocks 2000, 2004-2014 (about 2/3 of the block group) 26-3 blocks 3004-3006 (about 1/3 of the block group)
