And so, the rest of what you said above means what?
I spelled it out quite clearly.
If the 2010 census number of 309 million is believable, then it means that there were less than 13 million immigrants - illegal and legal combined - in the past decade.
It means that wild-eyed claims of 20 or 30 million illegal immigrants alone are completely insupportable.
I would also point out that - given the assumption by most observers that the majority of America's illegal immigrants are Mexican - the Mexican statistics on emigration imply 3.5 million illegal immigrants.
