The proportion of foreign-born Latino immigrants at the lowest end of the wage scale decreased by 6% in the decade ending in 2005, according to a report by the Pew Hispanic Center.



Mexican-born workers improved their wages, accounting for 40% of the lowest-wage group in 2005 compared with 48% in 1995. The proportion of Mexican-born workers in the middle-wage class increased from 15% to 19% during the same period.



The report also said that, unlike immigrants, African-Americans and native-born Hispanics enjoyed no changes in their wage-earning status over the 10-year period. That means time spent in the United States results in higher wages, regardless of where the immigrants come from.
