As long as we're discussing incredible numbers, (see post below) another one that I find interesting is the claim that there 12,000,000 illegal aliens walking the streets of the United States.
According to the U.S. Census Bureau, there were 299,398,484 people in the U.S.A. in 2006, of which 12.4%, or a tad over 37,100,000 were aged 65 or older. Now, unless you believe there are thousands of old people making their way across our long desert border with Mexico with canes, walkers, or wheelchairs, it is pretty unlikely that there are a significant number of elderly illegals.
Almost one-quarter of our population (24.6% or 73,650,000+) is under age 18. While it is true that adult illegal aliens do bring and/or start families here, it stretches even my vivid imagination to believe that they all are, in direct proportion to their purported numbers in the population at large (or almost 3,000,000 illegal children within our borders). In fact, while there is some documentation of villages in Mexico where there are few able-bodied men of working age to be found, I've yet to run across any that document wholesale abandonment of villages by the entire population. (Most mention households being run by women whose husbands have gone off to work.)
