The fifth of 49 notes on Chapter 20 of Give Us a Dollar and We’ll Give You Back Four (2012-13), this time on the public libraries of California.
California has relatively few libraries for its population—176 libraries and systems in the tables (with five omitted, including one very large system). Unusual expenditure levels are at the top (17.6% spending $73 to $399.99, compared to 9.8% overall) and lower middle (15.3% in the $21 to $25.99 bracket, compared to 10.9% overall). Adjusted for California’s high cost of living, the median adjusted benefit ratio is always at least 4.00. Circulation is on the low side, with half the libraries circulating fewer than 6 items per capita (36% overall). Patron visits are also slightly on the low side, with 46% of libraries having at least 5 visits (54% overall). Program attendance is considerably worse: 48% have less than 0.2 attendance per capita, compared to 30% overall. Similarly, 55% have less than one PC use per capita, compared to 43% overall.
On the budget side, circulation per capita correlates well with spending (except for a small step down at $26 to $30.99) and visits per capita correlate fairly well (except for a small step down at $17 to $20.99).

Tables
I used California as an example of the tables that could have been included in Graphing Public Library Benefits—but would have added 250 pages or so to an already-long ebook. Since that content is already handy, here it is: More than I’m providing for other states. This section covers 176 libraries and is copied unmodified from Chapter 20 of GPLB.
