Mark Mather explores the enduring impact of the U.S. Baby Boom on Race and Ethnicity. According to new population estimates from the Census Bureau, racial and ethnic minorities make up a growing share of the U.S. population—35 percent in 2009, up from 31 percent in 2000. However, one group —young adults ages 20 to 24—stand out because the proportion of minorities has stayed about the same, only increasing a single percentage point from 38 percent to 39 percent since 2000. Mather suggests that this anomaly may be partially explained by the recession, which has reduced the net inflow of young Latino immigrants to the United States.
