Studies underestimate Mexican Americans' economic progress, new research shows

Research by Brian Duncan and Stephen Trejo found that third-generation Mexican youth are more successful than previously reported, as many fail to identify as Mexican due to intermarriage with non-Mexicans. This 'ethnic attrition' skews results, leading to a downward bias in measures of attainment.
