Births rose for each race and Hispanic origin group, withincreasesrangingfromlessthan1percentfornonHispanicwhitewomen to6percent forAsian orPacific Islander (API)women.BirthstononHispanicblackandHispanicwomeneachincreasedbynearly2percent.

+ PreliminaryCBRsforstatesvariedconsiderablyin2007,rangingfrom10.5birthsper1,000totalpopulationinVermontto20.8inUtah (Table6). 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. Fertilityrates for the remaining states, District of Columbia, and U.S.Virgin Islandswereessentiallyunchanged.
