So I got a little OCD, and figured out how to do 2000 to 2001 comparisons and data.
9144 libraries, 30 numerical data pieces (including data divided by other data similar to the main dataline “Visits per Capita”). I ran an Rsquare test between VperC and each of the other data sets looking for correlation. It’s not encouraging as the best number was just over .16 — for total income per capita.
Neither 2000 nor 2001 collected the number of computers, just whether the libraries had internet access. Once I get a couple of those I’ll see if computers gives the anticipated high correlation.
