I'd like to find statistics on this. I'm less familiar with Texas than Florida, and my firsthand experience with Florida has me curious. I drove from Georgia to South Florida recently and saw lots of new development, including high rises and other multi family dwelling all over central and south Florida. Even the single family neighborhoods I saw were on average denser than what I am used to in Georgia. Florida may not be developing at the same density as NYC, but it is not all single family homes either.
