Napa County, California
The population data for Napa County come from three sources. Population counts for 1990 are from the 1990 Decennial Census (SF1 files). The population counts for 2000 are from the U.S. Census Bureau's population estimates program (http://www.census.gov/popest/). Those estimates are the April 1, 2000, base for the vintage 2009 county population estimates, which may differ slightly from the 2000 Decennial Census counts because of post-enumeration corrections. Population counts for 2010 are tabulated from P.L. 94-171 Summary Files released by the Census Bureau beginning in February 2011 (http://www.census.gov/rdo/data/2010_census_redistricting_data_pl_94-171_summary_files.html).
