Washington, Oct 17 One in eight of Chicago High School's female students are pregnant, it has been revealed.

CBS2Chicago.com has reported that out of the 800 female students at Paul Robeson High School in Chicago, Ill., 115 are expectant mothers.

Principal Gerald Morrow said that the staggering number can be attributed to various factors inside the home, not the school.

"It can be a lot of things that are happening in the home or not happening in the home, if you will," Fox News quoted Morrow as telling the network.

Morrow said that 'absentee fathers' are another factor in the school's high number of teen pregnancies.

According to a March 18 report from the Centers for Disease Control and Prevention's National Center for Health Statistics, the birth rate for teens ages 15 to 19 increased 5 percent from 2005 to 2007. (ANI)
