Daily Digit is the story behind the numbers that make our world work. Today we’re looking at the children of unauthorized immigrants. A new study finds 250,000 children were born to unauthorized immigrants in 2016, the last year for which this information is available. This is a 36% decrease from its peak number in 2007. Babies born to unauthorized immigrants accounted for roughly 6% of all U.S. births in 2016. This information comes at a time when President Trump has announced he wants to end birthright citizenship. However, the majority of Americans say birthright citizenship should continue.
