Changes in Total Library Visits, 2005-2011 and Visits Per Capita, 2011
Fiscal Year 2010 data were used for Atlanta, Chicago, Detroit, Pittsburgh and Seattle; 2011 numbers were not available. In some cities, total visits are based on annual turnstile counts. In others, visits are extrapolated from headcounts taken on selected days. Chicago was excluded from the change analysis because its number of visits was not available for 2005. Los Angeles was excluded from the per capita analysis due to the large number of pedestrians who use its main branch building as a pass-through.

Change in Library Circulation, 2005-2011 and Circulation per Capita, 2011
Circulation includes print and CD/DVD materials. It includes renewals but not electronic downloads, except in
Atlanta where downloads could not be separated from total circulation numbers. Fiscal Year 2010 data were used for Atlanta, Chicago, Pittsburgh and Seattle; 2011 numbers were not available. Detroit was excluded from the change in circulation comparison due to uncertainty about local data.

Library Spending Per Capita
Numbers represent all spending, including employee benefits and private expenditures. Baltimore, Brooklyn, Charlotte and Pittsburgh do not have separate foundations. In some library systems, certain maintenance and technology costs are covered by other local agencies; this chart does not capture those expenditures.

Library Branches per 10,000 Residents, 2011
Calculations include the main library as well as neighborhood and regional branches. Philadelphia’s Library for the Blind and Physically Handicapped is not included.

Change in Library Revenue from All Levels of Government
Figures include reported income from local, state and federal sources. Chicago is not included because officials there were unable to verify data for this time period.

Change in Full-time-equivalent Positions at Libraries, 2008-2010
Analysis is based on 2008 numbers from PLDS, which includes unfilled positions if a search for a new employee was underway, and 2010 numbers from our survey, which reflect filled positions at the end of the fiscal year. For Los Angeles, the calculation is based on total budgeted positions.

Change in Libraries’ Average Weekly Hours, 2008-2010
The San Francisco Public Library is not included in this graphic because multiple branches were closed for renovation during this period.
