The Census Bureau reported Wednesday that 35.7 percent of U.S. births were to unmarried mothers in 2011, but California's rate was markedly lower at 33.9 percent.
A number of other states had higher rates than California's, including rival Texas at 35.8 percent.
Among the states, Louisiana had the highest rate of births that year to unmarried mothers, 48.7 percent, although that was surpassed by the District of Columbia at 50.8 percent.
Utah was lowest at 14.7 percent.
