The total population of LA County is under 10 million! What is the source of this "estimate" ? It's not denying that there is a problem to ask for SOME evidence for the size and distribution of the problem. IF you take a deep breath and consider, I really don;'t think you believe that 55 to 110% of the population of all of LA County is illegal.
At the moment, LA County officially has about 11 million residents. But bear in mind, this is the official figure, derived from the last census.
Illegal aliens, by their very nature, cannot be accurately counted. All a reasonable man can say is that there are many, and their number should be added to the official census number to come up with the total population of the county.
I can say "Add 25 %," someone else can say "Add 40%," to set an estimate of illegal alien numbers. The state and local Government might estimate 10%. The crux of the matter is that no one has a very good idea of how many illegal aliens there are in LA County, or anywhere else.
Working backwards from the number of illegal alien children in LA public schools, or children whose parents are suspected illegals, we might well surmise that the Goverment estimates are very low. How low? My guess is at least as good as the government's, and that's the problem.
Last year, it was commonly reported that there were "..over 10 million illegal aliens in the country." This year, a commonly quoted figure is 12 million. But some researchers suggest that their work shows well over 20 million illegal aliens nation-wide.
Take a deep breath and walk through Inglewood, or Cudahy. You tell me your estimate of what percentage of the residents of LA County are illegal aliens. Remembering that LA County is 34,000 square miles, it is not inconceivable that one might realistically add another 3 million people to that official number.
