About six in 10 illegal immigrants who were deported in 2013 were deported because they had committed a crime, according to a new study.

The Pew Hispanic Center study shows 59 percent of deportations came as a result of a criminal conviction. Slightly more than half of these were aggravated felony or felony convictions (33 percent of all deportations), while the rest were misdemeanors (26 percent).

Another 20 percent of deportations came as a result of repeated immigration infractions, while 17 percent were deported after being caught crossing the border.

Deportations have increased under President Obama -- a statistic that has some immigrant and Latino groups crying foul.

The National Council of La Raza recent labeled Obama the "deporter in chief."
