You see the USAID signs across the island, mostly concentrated in inner-city communities in Kingston. This is a sign of the United States’ presence, in terms of foreign aid. The Washington Post has done a break-down of U.S. global foreign assistance. This story and this chart does not single out Jamaica, but I assume that one of the squares (in the upper left hand corner) for the Americas represents the country. (The text does not come through for the graphic, but the top ten largest recipients are:

Afghanistan, Israel, Egypt, Iraq, Jordan, Pakistan, Kenya, Nigeria, Tanzania and Ethiopia.

For what its worth, Colombia and Mexico receive $203.9 million and $85.6 million respectively.

This is the latest I could find in terms of foreign aid assistance, $21.7 million in 2012, targeted at crime and violence.  Here is the local USAID site for Jamaica.
