Nearly one in every 10 of the nation’s 3,141 counties has a population
that is more than 50 percent minority, the U.S. Census Bureau reported
The shift reflects the changing face of urban counties, the result of
legal and illegal immigration particularly from Central and South America
and the higher birth rate among blacks and Hispanics. The Census Bureau
predicts that by 2050, minorities will account for half of all US residents.
Nationally, the number of minorities topped 100 million for the first
time in 2006, to make up about one third of the population.
The two largest counties passing this threshold between July 1, 2005, and
July 1, 2006, are Denver County, Colo., and East Baton Rouge Parish, La.,
with total populations of 566,974 and 429,073, respectively. Three other
counties were in Texas (Winkler, Waller and Wharton), with one each in
Montana (Blaine), New Mexico (Colfax) and Virginia (Manassas Park, an
independent city and considered a county equivalent).
Los Angeles County, Calif., had the largest minority population in the
country in 2006. At 7 million, or 71 percent of its total, Los Angeles
County is home to one in every 14 of the nation’s minority residents. The
county’s minority population is higher than the total population of 38
states, with the largest population of Hispanics, Asians, and American
Indians and Alaska Natives in the country. It also has the second largest
population of blacks and Native Hawaiians and Other Pacific Islanders.
Harris County, Texas, gained 121,400 minority residents between 2005 and
2006, which led the nation. Harris (Houston is its largest city) now has a
minority population of 2.5 million, comprising 63 percent of its total. Its
minority population ranks third nationally, not far behind second place Cook
County, Ill. (Chicago).
Based on total population, Starr County, Texas, located on the Mexican
border, had the highest proportion of all counties that was minority, at 98
percent. Among the nation’s 25 most populous counties, Miami-Dade County,
Fla., had the highest proportion minority, at 82 percent.
