A pregnant woman aboard an Atlanta-bound jet had to make an unscheduled stop in North Carolina to deliver her baby after her water broke in mid-flight and the plane was diverted.
State health officials say North Carolina's infant mortality rate in 2013 matches the rate three years ago as the lowest ever.
The Public Health Division of the Department of Health and Human Services said Tuesday the rate for 2013 was 7.0 per 1,000 live births.
Palace officials say Prince William's wife Kate has given birth to a baby boy.
Officials said Monday the baby was born at 4:24 p.m. and weighs 8 pounds 6 ounces.
