Measures:

Birth Rate
The number of live births occurring to females in an age group per 1,000 females in the same age group. Formula = [Number of Live Births in an age group / Female population in same age group] * 1,000. (If a race is chosen, both the numerator and denominator are filtered by race).

Fetal Deaths
Death prior to the complete expulsion or extraction from its mother of a product of human conception, irrespective of the duration of pregnancy; the death is indicated by the fact that after such expulsion or extraction the fetus does not breathe or show any other evidence of life such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles

General Pregnancy Rate
The number of pregnancies that occur to women of all ages per 1,000 females ages 15-44 years of age. Formula = [Number of pregnancies / Female population 15-44 years of age] * 1,000.
Inadequate Kotelchuck Index & Percent
The Kotelchuck measure is an index of adequacy of prenatal care based upon month of entry, number of prenatal visits and gestational age of infant at birth. It uses American College of Obstetricians and Gynecologists standards for number of visits. The number of births by the "inadequate" value from the Kotelchuck Index, per 100 live births. Formula = [Number of Live Births with Inadequate Kotelchuck Value / Number of Live Births] * 100. (If a race is chosen, both the numerator and denominator are filtered by race).
Infancy
The period from birth through the 364th day of life.
Induced Termination of Pregnancy (ITOP)
The purposeful interruption of pregnancy with the intention other than to: 1) produce a live-born infant; or 2) to remove a dead fetus. An induced termination of pregnancy does not result in a live birth.
Induced Termination of Pregnancy (ITOP) Rate
The number of induced terminations of pregnancy that occur per 1,000 females per specified age group. All ages includes ages 10-55. Formula = [Number of induced terminations of pregnancy in age group / Female population in age group] * 1,000.
Late or No Prenatal Care Births & Percent
Births where the mother received prenatal care after the 2nd trimester, or not at all.
Formula = [Number of live births where the mother received prenatal care after 2nd trimester, or not at all / Number of live births] * 100.
Less Than 5 Prenatal Care Visit Births & Percent
The number of births where mother had less than 5 prenatal care visits, per 100 live births. Formula = [Number of live births with less than 5 prenatal care visits / Number of live births] * 100. (If a race is chosen, both the numerator and denominator are filtered by race).
Live Birth
The complete expulsion or extraction of a product of conception from its mother, irrespective of the duration of the pregnancy, which after such separation, breathes or shows any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles, whether or not the umbilical cord has been cut or the placenta is attached.
Low Birthweight Births & Percent
Live births of a birthweight less than 2500 grams (5lbs. 8oz.) per 100 live births. Formula = [Number of live births under 2,500 grams / Number of live births] * 100. (If a race is chosen, both the numerator and denominator are filtered by race).
Maternal Mortality
also known as Pregnancy, Childbirth and the Puerperium (Pregnancy and Childbirthing Complications). These are complications to the mother associated with pregnancy, childbirth and the time period surrounding these events. ICD10 codes O00.0 - O99.8 (ICD9 (630-676)). Formula = [The number of maternal mortalities / The total number of births] * 100,000.
Percent Births Within Area - Proportional Ratio (PR) Show me
The percent of births a selected age group is of all ages in a cluster, county or district.
[The number of births in a cluster, county, or district for a selected age group / The number of births in a cluster, county, or district for all age groups] *100.
Percent Births Within State - State Proportional Ratio
The percent of births a cluster, county or district contributes to Georgia births.
Formula = [The number of births in a cluster, county, or district / The number of births in Georgia] *100.
Percent of Births
The percent of Georgia resident births in a cluster, county or district among all births in Georgia.
Percent of Births to Women who reported drinking Alcohol during Pregnancy
The number of births to women who reported drinking alcohol during pregnancy per 100 live births. Formula = [Number of Births to Women who reported Drinking Alcohol during Pregnancy / Total Number of Live Births] * 100.
Percent of Births to Women who reported using Tobacco during Pregnancy
The number of births to women who reported using Tobacco during pregnancy per 100 live births. Formula = [Number of Births to Women who reported using Tobacco during Pregnancy / Total Number of Live Births] * 100.
Percent of Population
The percent of Georgia's female population represented by the cluster, county, or district
Pregnancy
A pregnancy is a human conception that results in a live birth, fetal death or an induced termination of pregnancy. The total number of conceptions that result in one or more live births, fetal deaths (of all gestational ages), or induced terminations of pregnancy are used to sum the total number of pregnancies. Therefore, Ectopic and Molar pregnancies are not included, and conceptions that result in multiple births (twins, triplets, etc.) are counted as one pregnancy.
Pregnancy Rate
The number of pregnancies occurring to females in a specified age group per 1,000 females in the specified age group. Formula = [Number of pregnancies in age group / Female population in age group] * 1000.
Premature Live Births & Percent
This measures uses gestational age (The gestational age of a fetus is the elapsed time since the first day of the last normal menstrual period. Gestational age is expressed in completed weeks.) The number of live births with a gestational age less than 37 weeks, per 100 live births. Formula = [Number of live births with gestational age less than 37 weeks / Number of live births] * 100. (If a race is chosen, both the numerator and denominator are filtered by race).
Repeat Births & Percent Repeat Births
The number of births to women who previously had at least one birth.
Formula = [Number of repeat births]/[Number of births]*100
Repeat Pregnancies & Percent
The number of pregnancies that are not first pregnancies per 100 pregnancies. For example, repeat pregnancy can be presented for females aged 10-19 and age groups between 10-19 (10-17, 10-14, 15-17, 18-19).
Formula = [Number of repeat pregnancies in age group / pregnancies in age group] * 100.
Very Low Birthweight Births & Percent
Live births with a birthweight less than 1,500 grams (3lbs. 5oz.) / Number live births] * 100. (If a race is chosen, both the numerator and denominator are filtered by race).
