The caption under the image says, "Couples may be married or cohabitating"
Are we really to believe that only 21% of American children are living with a "couple"?
That is a greater share than for households of U.S.-born residents (21%) or legal immigrants (35%). This difference stems in large part from the relatively youthful composition of the unauthorized immigrant population.
"Youthful"? Getting pregnant young is the first priority of illegal girls coming here.
We used to have a pool when a girl came to where I worked. It was obvious she was illegal. Invariably she would be pregnant within six months.
