Population Statistics for Maricopa County and Arizona

The U.S. Census Bureau has released their data estimates on population statistics for the period ending July 1, 2005. The actual census only takes place every ten years, in dates ending in a zero, the the next full census will take place in 2010. Because we continue to experience great population growth in Arizona, it's good to stop midway between census periods to see how we are doing.

Note: the numbers shown here for the year 2000 may not exactly coincide with the data from the 2000 census, which, generally, is as of April 2000, not July 2000.
