A perplexing statistic

I heard this comment on a morning news show earlier this week. They were expressing concern about the travel bans in or about to be put in place and concerned that foreign medical professionals would not be able to enter the United States. The statistic they quoted was "One in four doctors in the US is foreign born." Really, one in four??? I guess if someone had asked me I would have guessed one in ten.  One in four makes me wonder why their aren't more American born doctors? Don't our kids want to be doctors? Is the work too hard? Or could it be that this is one of those questionable statistics? A very wise person once said to me, "50% of all statistics are made up on the spot." Think about it.
