Birth data on OK2SHARE are the facts at Birth and do not reflect updated information due to adoptions or amendments.

Live birth: An infant with signs of life at birth.
County: The county of residence (map of state)
Time Span: The years during which the event occurred (birth date of infant)
Fertility: Births to a particular population of women (i.e. age group and/or race)

Childs Weight:
    Very low: A live birth weighing less than 1,500 grams (3 lb. 5 oz. or less).
    Low: A live birth weighing less than 2,500 grams (5 lb. 8 oz. or less).
    Normal: A live birth weighing between 2,500 and 3,999 grams (5 lb. 9 oz. - 8 lb. 13 oz.).
    High: A live birth weighing 4,000 grams or more (8 lb. 14 oz. or more).

Mother's Race:
    Beginning with 1990, all Race/Ethnic specific rates are calculated using population estimates from the National Center for Health Statistics with bridged race categories.

    The National Center for Health Statistics has discontinued the postcensal bridged-race population estimates (used for calculating rates) with the release of the Vintage 2020 estimates. Starting with 2021 death statistics, OK2SHARE will display the racial categories used by the U.S. Census Bureau - White, Black, American Indian, Asian, Native Hawaiian and Pacific Islander, and Two or more races. Hispanic Origin did not change. There will also be 2010 to 2020 trends using the new race categories along with the existing bridged race categories.

  Birth Rate = 1000 x Number of Resident Live Births / Resident Population
  Fertility Rate = 1000 x Number of Resident Live Births / Female Resident Population ages 15 - 44

***when calculating the rate for combined years the population is the sum of the populations for the specified time span***
