Ah—here’s the rub my friend:  the whole country was not tracted in those censuses.

If my cranky old memory serves: what you can get by filtering at NHGIS is what exists for 20 thru 50.  (Major cities and surrounds) or counties.

All,

I would like to find a website where I can see the US Census by tract (not county) for the 1920, 30, 40, 50, .... Census.

The complicating part is seeing by tract, not county.

Many thanks in advance.
