The numbers are suspect. San Antonio only shows a little over 1000 births for illegals and it is one of the cities with a lot of them.
Perhaps SA isn’t not even inquiring about citizenship and only recording info if it is offered.
Last year at Parkland, 11,071 babies were born to women who were noncitizens, about 74 percent of total deliveries.
Likely, similar percentages elsewhere...even if they are officially reported .
It is suspect! San Antonio is little Mexico. I have a liberal morderate friend that lives there(I’m in Dallas) and she says even she’s sick of it and how awful it is.
