Immigrants now make up the largest share of the U.S. population since the 1920s.

In the 1920's, immigrants were required by law to register. There were very real consequences for not doing so. Right now, there is no registration process at all unless you voluntarily turn yourself in and request government assistance. I'm not sure how they can even statistically calculate the current percentage by any accurate means.
