WASHINGTON (AP) — Preliminary census estimates show U.S. racial minorities accounted for roughly 85 percent of the nation's population growth over the last decade. Hispanics accounted for much of the gain in many of the states picking up new House seats.

Census numbers also suggest the number of multiracial Americans has jumped to over 5 million.

The findings are based on fresh government survey data. They offer a glimpse into the official 2010 census results that are being released on a state-by-state basis beginning this week. New Jersey, Mississippi, Virginia and Louisiana are the first to receive the census redistricting data.

Redistricting experts say the numbers suggest several new Hispanic officials stand to be elected once states complete the contentious process of redrawing political districts based on population and racial makeup.
