From World Bank economist Dilip Ratha's Blog about migrations, remittances and development:
"By the way, if you are wondering whether Haitian immigrants are too poor to invest, consider this fact from the Current Population Survey of the US: nearly one-third of Haitian immigrants in the US belong to households that earned more than $60,000 in 2009. In comparison, less than 15% of the immigrants from Mexico, Dominican Republic and El Salvador in the US had that level of household income. A quarter of Haitian immigrants, especially women, are reportedly in the relatively higher paying health care and education sectors; only a small number of them are in the construction sector."
