The Natality online databases report counts of live births occuring within the United States to U.S. residents and non-residents. Counts can be obtained by state, county, child's gender and weight, mother's race, mother's age, mother's education, gestation period, prenatal care, birth plurality, and mother's medical and tobacco use risk factors. The data is derived from birth certificates. For more information, refer to Natality data description.

Select from following:

Natality for 2003 - 2005

Natality for 1995 - 2002

The Natality data are offered in two separate online databases because of changes in data reporting standards beginning in 2003. The race group categories changed from 8 categories for the years 1995-2002 to 4 "bridged-race" categories for the years 2003-2005. Beginning in 2003, county-level data are available for 66 additional counties, because the 2003-2005 data reference the year 2000 census to determine suppression for counties with populations less than 100,000 persons. The 1995-2002 data reference the 1990 census to determine county-level data suppression.
