Since it's supposed to be calculated on the number of adults, you have to exclude under-21.Paladin wrote: I think it is supposted to be the total number of adults.
Texas has 247345 permits with a population of 22,490,022, which give a number of 1.0998%, so the number's may be a little off... or maybe they are supposed to be number of ELIGIBILE adults?
I'd consider all the numbers a rough estimate <shrug>
Census.gov says that in 2004, Texas had 21,912,164 residents, and 15,662,245 were 18 or older. Assuming a fairly constant ratio from 18 to 21, we can subtract just over a million in that range to give us 14,620,590 residents who are 21+.
Using your number of 247,345 CHLs, we get 1.69% of the 21+ population.
