Armed conflict, political turmoil, social factors..Actually, a variety of factors have curbed illegal immigration. Not just the economy.You do know immigration was rapidly increasing for a period until recently? That makes the older link even more valid. The other link does not require a subscription, I can view it just fine.You can look at the data yourself.
Immigration is stabilized.
Well one of your links is from 1997 and the other requires a subscription to read. So yes your links are worthless.
And as someone who's lived within a hundred miles of the border and currently in Houston where we have a huge immigrant population I can honestly say with a great deal of accuracy that you're full of shit.
Our jails are full of mexicans and south americans and the border is a sieve.
You do realize when the economy sucks they stop coming right?
I can even tell you when the next slow down will be that clowns like you will tout as "good border enforcement"
Oh really?
So has the economy improved in mexico when I wasnt looking or something?
Lets hear your "variety of factors".
