Isn't it doughnut time for you fatty?
if there are 878,000 illiterate people in north carolina out of a population of 9.5 million, that's an illiteracy rate of ~9%
if there are 530,000 illiterate people in louisiana out of a population of 4.5 million, that's an illiteracy rate of ~12%
The funny thing about it is that you don't take the result of a different population size and plug that result for a different population. NC has 14% and LA had 16%, so use those numbers if you insist on those new population figures. Also. Go to the site I gave you which is the official govt site on illiteracy numbers and you will see the population figures as of last testing was 6.6 mil and 3.5 mil population sizes.
