My own town has concealed carry licenses issued to about one in twenty adult residents.
In Florida, according to Census data, there's about 4.1 million residents over the age of 18 in the 2006 estimate, and 463,760 active licenses, so that's 11.3% of the eligible population.
However, 48,304 of those are non-resident licenses, so that brings the percentage down to 10.1%.
But that reduction in the percentage may be offset by the fact that adults age 18-20 are denied their right to carry a concealed defensive firearm, reducing the overall eligible population from 4.1 million to something smaller.
While it's not a "big" percentage, it's quite a bit more than "miniscule."
You're nitpicking. Is the number anywhere near enough to form a majority vote? Of course not. But it's a place to start.
