I did read it. But maybe I'm misinterpreting.

The same pattern is present among all Latino origin groups, though for three—Ecuadorians, Mexicans and Nicaraguans—the number of immigrants has declined since 2010 (for details, see Appendix Table A2).

The foreign-born share of Salvadorans, for example, fell from 76% in 2000 to 59% in 2013—the largest percentage point decline of any of the six largest Hispanic origin groups. Similarly, Dominicans, Guatemalans, and Colombians all had decreases of over 13 percentage points in their foreign-born shares over the same period. Mexicans, the nation’s largest Hispanic origin group, also saw a decline, though it was only 8 percentage points since 2000.
