Births (Georgia OASIS)

Limitaciones

Live births to Georgia-resident mothers by county of residence. birth_rate_per_1k_females is births per 1,000 females aged 10-55 (or the row's age group), not per 1,000 residents (unlike census/estimated_births). general_fertility_rate_per_1k (per 1,000 women 15-44) is the standard measure. Rates are NULL on 1-4 births. Race groups break in 2007-2008 (recording, our reading): compare them from 2010 (Georgia) or 2013 (counties); NULL where over 20% of a place-year's births lack race (our mask). Live births to mothers who live in Georgia, placed by the mother's county of residence (not where the birth happened); OASIS counts births, not pregnancies, so twins are two births. demographic and mother_age are never crossed: a race group's row has mother_age = 'all', and a mother's age row has demographic = 'all'. OASIS publishes every birth count, however small, and withholds rates on 1-4 births (NULL here); the platform adds no suppression of its own and never recomputes a withheld rate. 22% of rows with at least one birth have no birth rate, mostly 1-4 births in small counties and groups. A race group with no residents in a county has no rate (NULL; OASIS shows 0, our mask), and neither has one whose residents include nobody aged 10-59 (our mask: no females of the rates' ages); one with residents of those ages but no females 10-55 keeps OASIS's 0, which the population module cannot tell apart (it has no female population by race). Where race or ethnicity is unknown for more than 20% of a place-year's births (race_unknown / all), the race groups' births and rates for that place and year are NULL (our mask, OASIS's own 20% threshold for missing items): each group's count would miss its share of the unknowns, so its rate runs low and its trend follows the recording, not the group. The all, mother's age and race_unknown rows are kept, so the unknown share stays visible. That covers 97 place-years (2000-2012, 19 counties; 679 race-group rows). The race groups' series break in 2007-2008, which looks like a change in how the mother's race was recorded (our reading; OASIS documents none): multiracial births rose from 648 in 2006 to 3,538 in 2007 and 6,961 in 2008, then held between 2,487 and 3,499 a year from 2010, so multiracial figures of 2007-2009 are not comparable with other years (the highest rate here, 964 per 1,000, is multiracial births in county 13051 in 2008); white births fell from 66,940 to 57,568 and native_american births from 215 to 91 in 2008. race_unknown (unknown ethnicity, and in 2008-2016 also births recorded with no race) peaks at 5.1% of Georgia's births in 2009 (0.6% in 2025), so the race groups run that much low. Counties break harder and for longer: in 84 county-years of 2000-2012 (none since; 17 counties) more than 25% of births have no recorded race or ethnicity, up to 78%, most often in Catoosa, Dade and Walker (the Tennessee border) and in Tift and nearby counties from 2007, so OASIS's race groups for those county-years run far low (Tift: 414 of its births in 2011 had no recorded race or ethnicity, and OASIS counts its black births as 16 in 2011 and 199 in 2015). Hispanic births spiked in Sumter, Walton and Macon in 2008-2009 (Sumter: 92, 336, 290 and 56 in 2007-2010), so Sumter's and Macon's Hispanic fertility rates of 2008 are 954.5 and 960.0 per 1,000. Compare a county's race groups over time from 2013 only (its race_unknown share has been at most 17% since). Those county-years, and the others with more than 20% of births of unknown race, have their race groups NULL here (our mask), Tift's 2011 black births among them. Race groups are the mother's race and ethnicity in the platform convention: hispanic is Hispanic of any race; white, black, asian, native_american (American Indian or Alaska Native), pacific_islander (Native Hawaiian or Other Pacific Islander) and multiracial are non-Hispanic. race_unknown is our calculation, the total minus those seven (unknown ethnicity, or non-Hispanic of unknown race), so the race groups add up to all where every group's count is published (our race mask NULLs them in the place-years where race is mostly unknown); it has no rate. mother_age is the mother's age at the birth in OASIS's groups (10_14, 15_17, 18_19, then five-year groups to 40_44, and 45_55); the groups add up to all. OASIS splits the teen years into 15_17 and 18_19 and publishes no 15-19 rate. The 45_55 group and the all-ages birth rate include mothers and females aged 55. OASIS's fertility rate on a mother's age row divides that group's births by all women 15-44 (the total's denominator), so it is not carried there. num_females_15_44 is OASIS's population module (females 15-44) on the all-ages totals only; num_births x 1,000 / num_females_15_44 reproduces every fertility rate there. Race rows have no population: OASIS's rates are kept as published and do not pool. 2025, the newest year, was added to OASIS on 2026-04-30; OASIS marks no year provisional. Counties add up to Georgia, and the mother's ages and the race groups (with race_unknown) to all, except a race group's births in the 97 county-years (2000-2012) our race mask NULLs: there a race group's counties fall short of Georgia's row, and the race groups of all. Not served here: OASIS's SES-vulnerability and payer rows (their rates divide every group's births by the whole place's females 10-55, so they are not rates of the group) and the mother's education. Birth outcomes, prenatal care, tobacco use, breastfeeding and payer are other topics. tract_geoid is always NULL.
