The electorate in last year's presidential election was the most racially and ethnically diverse in U.S. history, with nearly one-in-four votes cast by non-whites, according to a new analysis of Census Bureau data by the Pew Research Center. The nation's three biggest minority groups—blacks, Hispanics and Asians—each accounted for unprecedented shares of the presidential vote in 2008.
Overall, whites made up 76.3% of the record 131 million people who voted in November's presidential election, while blacks made up 12.1%, Hispanics 7.4% and Asians 2.5%. The white share is the lowest ever, yet is still higher than the 65.8% white share of the total U.S. population.
The unprecedented diversity of the electorate last year was driven by increases both in the number and in the turnout rates of minority eligible voters.
The levels of participation by black, Hispanic and Asian eligible voters all increased from 2004 to 2008, reducing the voter participation gap between themselves and white eligible voters. This was particularly true for black eligible voters. Their voter turnout rate increased 4.9 percentage points, from 60.3% in 2004 to 65.2% in 2008, nearly matching the voter turnout rate of white eligible voters (66.1%).
For Hispanics, participation levels also increased, with the voter turnout rate rising 2.7 percentage points, from 47.2% in 2004 to 49.9% in 2008. Among Asians, voter participation rates increased from 44.6% in 2004 to 47.0% in 2008. Meanwhile, among white eligible voters, the voter turnout rate fell slightly, from 67.2% in 2004 to 66.1% in 2008.
