Wait, I thought we only had 12 million illegal aliens in this country. Isn’t that the number that has been thrown around for the past 15 or 20 years?
Look at the numbers. There were 281 million US residents in 2000 and 309 million now in 2010.
The US natural population growth rate is about 0.55%.
If 281 million grew by 0.55% over 10 years, the result would be 15.8 million more people.
Additionally, the total net migration ratio (legal plus illegal less emigrants) is .043%.
Over ten years on a base of 281 million that yields 12.2 million more people.
So 15.8 plus 12.2 yields 28 million more people or 309 million.
Of that 12.2 million in newcomers, not all were illegal.
The number of illegal immigrants in this country is greatly exaggerated by some - although the census numbers likely undercount the number of illegal immigrants significantly.
I'll also point out that the demographics of Mexico do not support the thesis that more than 15 million Mexicans have entered the US illegally - or even that as many as 10 million have.
