The Pew Hispanic Center, a project of the Pew Research Center, launched a new Census 2010 feature on its website. This feature provides state and county population data by Hispanic origin in 2010 and 2000 in the form of downloadable Excel files. Each file contains the total, non-Hispanic and Hispanic populations in each state and counties within that state. Numeric and percent changes in the populations from 2000 to 2010 are also included.
