I need data aggregated at a county level with information as the following:
-number of total whites in county x;
-number of total afro-american in county x;
-number of whites in college in county x;
-number of afro-american in college in county x.
And so on. In particular I am interested in education and income data for these two ethnicities in the 1950 (possibly also in 1960 and 1970).
I am aware that in ICPSR there is a similar study, however there are no data on blacks separately.
I have already downloaded the IPUMS data but the best geographic identifier I can find id the Standard Economic Area. I am aware that the county of residence is not public if I want Census 1950 micro-data. I was wondering instead if something similar to what I am looking for exists.
