While talking with some people the other night at a showing of the movie Poto Mitana Haitian-American woman mentioned how surprised she was at the number of Haitians she ran into while traveling through Georgia. So, using the American Community Survey, I created an Excel file of the Haitian population by state (2006-2008) (28kb). Note that this is based on self-reported data, so it certainly undercounts the numbers. Also, the data is a few years old. However, since the "undercounting" is likely fairly even across states, the relative sizes by state are interesting to see.
I was surprised to see the population in FL double that of NY and NY, in turn, double that of MA. Also, due to the margins of error, you could say that MA and NJ nearly tie for third. GA, PA, and CT all tie for fourth. Given the number of Haitians in Maryland, I was surprised that VA has so much fewer, and that it lost out to both IL and CA! Again, it is unknown what number of Haitians do not report ancestry. I will see if I can ring up somebody at Census to get their thoughts on estimating that number.
Here's a summary table of the top states (the file linked above has all states) :
