How much does the U.S. Government spend on aid to Haiti?

One noted humanitarian and broadcaster suggested that Americans already provide enough aid to Haiti "through the income tax." How much aid does the United States provide? This state department page on Haiti says that

The U.S. has been Haiti's largest donor since 1973. Between FY 1995 and FY 2003, the U.S. contributed more than $850 million in assistance to Haiti. Since 2004, the U.S. has provided over $600 million for improving governance, security, the rule of law, economic recovery, and critical human needs. The President's budget request for FY 2007 was $198 million. U.S. Government funds have been used to support programs that have addressed a variety of problems.

By my back-of-the-envelope calculations, based on these data and some generous assumptions, the United States spent, between FY 1995 and FY 2010 (pre-disaster) about $2.1 billion on aid to Haiti, by the State Department's reckoning. I calculate that about 62 ten-thousands of one percent of the U.S. Federal budget (0.0062%) was spent on aid to Haiti. A well-off taxpayer who pays $15,000 in federal income taxes will then contribute about 92 cents per year to Haiti through foreign aid, assuming that income taxes were the government's only source of revenue. At about $95 million a year, I can imagine that private charity this year will exceed the typical annual U.S. aid to Haiti.  

Americans routinely overestimate the amount and proportion of American foreign aid spending, although in the early 2000s it appears Americans' support of foreign aid grew, so our broadcaster's attitudes on the issue place him squarely in the fringe of mainstream thought--and that's not news.
