I wasn't sure, but had based my statements on conversations with local Mexicans. I checked on Google, though, and found that Mexicans only represent 7% of the DC hispanics... I stand (almost) corrected.
• There is a larger number of bilingual Latinos in the Washington area as compared to the national average. This is a reflection of the higher educational and economic levels of the Washington community.
• In terms of ethnicity, Salvadoreans represent the dominant Latino subgroup in the Washington D.C. area (29%), followed by Bolivians, Puerto Ricans and Nicaraguans (around 8% each), Mexicans (7%), Guatemalans and Colombians (6%) and Cubans (5%). It is one the most diverse Latino markets in the United States.
Yes, and in Fairfax I suspect Mexicans are not particularly welcome! Why that family with a bunch of children were putting themselves at risk around here I can't imagine.
