The Mexicans that have stopped coming and started returning are more than replaced by Guatemalans, Salvadorans, and Hondurans that have started arriving in much greater numbers.<p>Mexico&#x27;s fertility rate is down to replacement level and the country won&#x27;t be sending more.<p>Guatemala is packing 16MM people into a place the size of Maine, half of it malarial jungle and half volcanic mountaintop. The fertility rate is 4.0, setting population to double every generation. Honduras and El Salvador aren&#x27;t far behind. Those Central American countries are desperately poor with illiterate majorities, the world&#x27;s highest murder rates, and low educational attainment. Nearly half of Guatemalans don&#x27;t even speak fluent Spanish.<p>Meanwhile Mexico is a well educated nation on the verge of first world incomes.<p>So the quality of migrants is not looking up. But the quantity certainly is.
