Survey data suggests the public values free public libraries. A Public Agenda survey in 2006 reported 84% of the public said maintaining free library services should be a top priority for their local library. Public libraries received higher ratings for effectiveness than other local services such as parks and police. But the survey also found the public was mostly unaware of financial difficulties facing their libraries. In various cost-benefit studies libraries continue to provide returns on the taxpayer dollar far higher than other municipal spending. A 2008 survey discusses comprehensively the prospects for increased funding in the United States, saying in conclusion "There is sufficient, but latent, support for increased library funding among the voting population." A 2013 Pew Research Center survey reported that 90% of Americans ages 16 and older said that the closing of their local public library would affect their community, with 63% saying it would have a "major" impact.
