Birth rates for 13 states (Alabama, California,Indiana, Kansas, Kentucky, Louisiana, New Jersey, New York,Ohio, Pennsylvania, Texas, Washington, and West Virginia)increased significantly between 2006 and 2007, whereas birthratesforthreestates(Arizona,Colorado,andMichigan)andthreeterritories(AmericanSamoa,PuertoRico,andNorthernMarianas)decreasedsignificantly.Theratesfortheremainingstates,DistrictofColumbia,andU.S.VirginIslandswereessentiallyunchanged(i.e.,notstatisticallydifferent).

GFRs for states varied considerably in 2007 as well,ranging from 53.2births per1,000womenage1544years inVermont to 94.4 in Utah (Table6). Fertility rates increasedsignificantly for 30 states between 2006 and 2007 (Alabama,California,Florida,Georgia,Hawaii,Idaho,Illinois,Indiana,Iowa,Kansas,Kentucky,Louisiana,Maryland,Minnesota,Mississippi,Missouri, Nevada, New Jersey, New Mexico, New York, NorthCarolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas,Virginia, Washington, West Virginia, and Wisconsin). However,fertility rates for three territoriesonly (AmericanSamoa,PuertoRico, and Northern Marianas) decreased significantly.
