There are many differing opinions, resulting in some heavy argument. As they are ILLEGAL, there are no records to actually establish a number.
The LOW estimate crowd acknowledges
at least 12 million, while the
HIGH estimate crowd says it is
more like 20 to 30 million.
Then there is a group that
says that those numbers are only the recent [within say the last 30 years] ILLEGAL ALIENS. This group claims that the "old timer" illegal aliens [from 30 years and backward]
may represent another 20 to 30 million [including their offspring over the years].
Again,
there is NO WAY of knowing the exact numbers, but clearly and without valid argument it is in the area of at least/more than 12 to 20 million.
There are approx 10,000 total additional illegal aliens added to the United States population each day.
