Household incomes in most of the island have stayed pretty much the same since 2007, according to the latest Census figures. Puerto Rico's median household income was $19,518 during 2010 to 2012, statistically no different than from 2007 to 2009.

By contrast, the survey found household income for Puerto Ricans in the Miami metro area was $47,516, and in Chicago and New York it was about $37,262.

Unlike the U.S., the island's economy has not seen economic growth since the recession and the economy is expected to contract again this year.

The median household income in 3 of the largest "municipios" showed decreases; in the San Juan metro area income dropped to $22,734 (in 2012 inflation-adjusted dollars) from $24,565 during 2007 to 2009.

According to the survey, 46.1 percent of Puerto Ricans who are 25 and older are in the labor force. The area of Guaynabo had one of the highest employment rates at 57.7 percent, while Lajas had one of the lowest at 25.7.

In the U.S., 67.7 of Puerto Ricans in the Miami metro area and around 64.7 percent in Chicago and in New Haven, Connecticut were in the labor force.
