Latinos 50% of U.S. Population Growth Since 2000
The growth in the 1990s was 40%.
A point of interest to note is that the Latino population growth in the new century has been more a product of the natural increase (births minus deaths) of the existing population than it has been of new international migration.
As of mid-2007, Hispanics accounted for 15.1% of the total U.S. population. That number is expected to be 30% by 2050, according to the Census.
