One in 12 babies born in the U.S. in 2008 were offspring of illegal immigrants, according to a new study, an estimate that could inflame the debate over birthright citizenship.
Undocumented immigrants make up slightly more than 4% of the U.S. adult population. However, their babies represented twice that share, or 8%, of all births on U.S. soil in 2008, according to the nonpartisan Pew Hispanic Center's report.
This is a large number and will certainly figure into the public discussion of the 14th Amendment and "anchor babies". The report does note that over 80% of the mothers had been in the US over a year. So, that makes about 20% of the 8% first time "anchor babies". I calculate that as over 1% of US births in 2008 were clearly "anchor baby" phenomena.
I noticed the Wall Street Journal article and the Pew report, Unauthorized Immigrants and Their US-Born Children, assume the 14th Amendment guarantees citizenship to the children of illegal immigrants who are born in the US and that a revision to the constitution is necessary to deny birthright citizenship to the children of illegal aliens. But I thought that was an open question since the 14th Amendment includes the language "subject to the jurisdiction thereof".
