Definitions
- Adolescent fertility rate > Births per 1,000 women ages 15-19: Adolescent fertility rate (births per 1,000 women ages 15-19). Adolescent fertility rate is the number of births per 1,000 women ages 15-19.
- Birth rate, crude > Per 1,000 people: Birth rate, crude (per 1,000 people). Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
- Contraceptive prevalence > % of women ages 15-49: Contraceptive prevalence (% of women ages 15-49). Contraceptive prevalence rate is the percentage of women who are practicing, or whose sexual partners are practicing, any form of contraception. It is usually measured for married women ages 15-49 only.
- Fertility rate, total > Births per woman: Fertility rate, total (births per woman). Total fertility rate represents the number of children that would be born to a woman if she were to live to the end of her childbearing years and bear children in accordance with current age-specific fertility rates.
- Low-birthweight babies > % of births: Low-birthweight babies (% of births). Low-birthweight babies are newborns weighing less than 2,500 grams, with the measurement taken within the first hours of life, before significant postnatal weight loss has occurred.
- Maternal mortality ratio > National estimate, per 100,000 live births: Maternal mortality ratio (national estimate, per 100,000 live births). Maternal mortality ratio is the number of women who die from pregnancy-related causes while pregnant or within 42 days of pregnancy termination per 100,000 live births.
- Maternity leave > Weeks of leave given: Maternity leave benefits.
- Mortality rate, infant > Per 1,000 live births: Mortality rate, infant (per 1,000 live births). Infant mortality rate is the number of infants dying before reaching one year of age, per 1,000 live births in a given year.
- Mortality rate, neonatal > Per 1,000 live births: Mortality rate, neonatal (per 1,000 live births). Neonatal mortality rate is the number of neonates dying before reaching 28 days of age, per 1,000 live births in a given year.
- Mortality rate, under-5 > Per 1,000 live births: Mortality rate, under-5 (per 1,000 live births). Under-five mortality rate is the probability per 1,000 that a newborn baby will die before reaching age five, if subject to current age-specific mortality rates.
- Mortality rate, under-5, female > Per 1,000 live births: Mortality rate, under-5, female (per 1,000 live births). Mortality rate, under-5, female (per 1,000)
- Mortality rate, under-5, male > Per 1,000 live births: Mortality rate, under-5, male (per 1,000 live births). Mortality rate, under-5, male (per 1,000)
