Illinois public libraries

Posted in $4 on January 7th, 2013

Another post commenting on Chapter 20 of Give Us a Dollar and We’ll Give You Back Four (2012-13)–now available as a $9.99 Kindle ebook or $21.95 paperback with ISBN 978-1481279161 on Amazon, along with the usual Lulu options.

The 622 profiled libraries (12 omitted) are generally well funded, with more than 100 (16.6%) in the top bracket (at least $73 per capita) and only 15.7% in the bottom three brackets combined (compared to 28.2% overall). Circulation tends to be slightly high, with only 28% circulating fewer than 6 items per capita (compared to 36% overall). Circulation per capita and expenditures track perfectly, as is also the case in the budget table (where all figures—25%ile, median and 75%ile—rise consistently with expenditures). Visits per capita are strong in the upper middle, while program attendance and PC use are both fairly typical in distribution.
