There are ~66,000 Census Tracts, meaning they're possible, but expensive. Will increase the footprint ~15MB. If there's any customization (e.g. state FIPS code truncation), MicrobeTrace won't know what to do with it.
There are ~8,000,000 Census blocks which is much too large, and probably too granular (i.e. avg. population < 40 people/block).
Census block and census tract, for example.
