Hispanics in Greater Cincinnati2
Why do they come?3
"Most immigrants in Ohio come for economic reasons....In Mexico, half of the people live in poverty and 20 percent in conditions of severe poverty and hunger. The statistics are similar for Guatemala..."
" The wage differential between Mexico and the United States has for the last 30 years been about 10:1, that is, for every dollar one can make in Mexico, one can make ten dollars here in comparable usually unskilled labor.... Mexico's minimum wage is about $4.50 per day (varying from region to region), while the average daily wage is about $7.00 per day. Central American wages are even lower than those in Mexico. The lack of jobs and the much higher wages in the United States are the driving force behind most migration."
