New Mexico public libraries

Posted in $4 on February 20th, 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 80 profiled libraries in New Mexico (11 omitted) range broadly in terms of spending, but with quite a few at the top (24%) and very few at the bottom (only 18% in the bottom three brackets combined). Circulation is on the low side, with only 36% circulating at least six items per capita (compared to 64% overall). On the other hand, patron visits are strong: 35% have at least nine visits per capita (compared to 20% overall). More libraries than usual are in the top bracket for program attendance, although the numbers are fairly typical below that group of 13 libraries—and PC use is very strong, with 46% of the libraries having at least 2.25 uses per capita (compared to 19% overall).

54,000-104,999 3 3.8%
105,000-4.1 mill. 3 3.8%

I believe this may be the smallest number of libraries so diverse as to have at least one in each of the 17 size brackets!
