Yes. But we also call redheads "redheads" as a rule, not "gingers" - except that the "ginger" thing has filtered over here via the Internet in the past, I dunno, 20 years.

Like, I can't recall anybody describing a redheaded person as a "ginger" in the 80s or 90s, (location: Missouri) it's something I've only encountered since there's been more language cross-pollination due to the Internet.

South Park really spread "ginger" as the term in the US. Since that episode, everyone I know uses ginger instead of redhead, whereas I only learned the word ginger from that episode.
