I am looking for mean and median per capita income data for each US-American state and for each decadal year from 1950 to 2010. Ideally, I would like to see the data combined in one data set (in total or per year).
I have found quite a few data sets already but most them date only back to the 1970ies or 80ies. Also, I found this series of data sets where the income data is listed separately for each state but (for now) I would like to save me the trouble of downloading and merging all of these individually. I assume, there must exist some complete data sets on this topic.
