On January 22, 2003, the U.S. Census Bureau releases detailed statistics on race and ethnicity, the first time such numbers had been released since the 2000 census. The numbers showed that the Hispanic population of the United States had increased by 4.7 percent since the last count, officially making Hispanics the largest minority group in the country.
The trends of the last several decades had indicated that this milestone was approaching. The foreign-born population of the United States had been increasing exponentially, from just 9.6 million in 1970 to 31.1 million by 2000, and immigrants from Latin America accounted for a large percentage of those newcomers. The 2000 census showed that 29 percent of immigrants in the U.S. had come from Mexico alone, while immigrants from other Latin American nations made up another 22 percent. Birth rates in the Hispanic-American community were also among the highest in the nation.
