资源简介：
This dataset was created from County Business Pattern data ranging from 1962 to 1969 excluding data from 1963. The investigators of these data did their best to infer structure and meaning from the individual datasets to create this dataset. The 1962 data do not contain all counties. The investigators observed that multiple counties were combined together into single observations for the states with the most counties, so as to save storage space.
