Definitions
- 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.
- 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.
- 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)
