Population Projections by County

Note: EPA no longer updates this information, but it may be useful for historical purposes.

Listed below are links to State websites that have county population projections. The State data have been accumulated into one large data base with all counties available listed. If a State has data for 2000 and 2010, all years between these dates have been estimated using straight line interpolation. Since different States project to different years, this procedure allows the user to have data for any year of interest. Data were not interpolated beyond the last year of the State's projection.

• All States Summary
• All States / All Years available Zipped Database (dbf), Excel (xls) and Wordperfect (wpd-summary) file
• Definition of the data columns in the summary, database and spreadsheet

This is a work in progress and will be updated as updated State web pages are found. On the left under the State name is a copy of the State population data for fast retrieval (and in case the State website is temporarily down). On the right is a the State website where the data were found.
