Carrying Capacity
The number of people a given area's natural resources can support
Physiological Population Density
The number of people in a country per unit of arable land; formula = population divided by arable land in km2;
Median Age
The age that divides a population into two numerically equal groups; that is, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
Net Migration Rate
The difference between the number of persons entering and leaving a country during the year per 1,000 persons. An excess of persons entering the country is referred to as net immigration; an excess of persons leaving the country as net emigration.
Urbanization
The percentage of the total population living in urban areas, as defined by the country.
Sex Ratio
The number of males for each female.
Mother's Mean Age at First Birth
The mean (average) age of mothers at the birth of their first child.
Infant Mortality Rate
The number of deaths of infants under one year old in a given year per 1,000 live births in the same year.
Life Expectancy at Birth
The average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future.
Contraceptive Prevalence Rate
The percent of women of reproductive age (15-49) who are married or in union and are using, or whose sexual partner is using, a method of contraception according to the date of the most recent available data. The contraceptive prevalence rate is an indicator of health services, development, and women's empowerment.
Drinking Water, Improved
The use of any of the following sources: piped water into dwelling, yard, or plot; public tap or standpipe; tubewell or borehole; protected dug well; protected spring; or rainwater collection.
Physicians Density
The number of medical doctors (physicians), including generalist and specialist medical practitioners, per 1,000 of the population. The World Health Organization estimates that fewer than 2.3 health workers per 1,000 would be insufficient to achieve coverage of primary healthcare needs.
Hospital Bed Density
The number of hospital beds per 1,000 people; it serves as a general measure of inpatient service availability.
Improved Sanitation
The use of any of the following facilities: flush or pour-flush to a piped sewer system, septic tank or pit latrine; ventilated improved pit (VIP) latrine; pit latrine with slab; or a composting toilet.
School Life Expectancy
The total number of years of schooling (primary to tertiary) that a child can expect to receive
Share of Labor Force in Agriculture
Share of people of working age who were engaged in any activity to produce goods or provide services for pay or profit in the agriculture sector
Child Marriage
The prevalence of child marriage in a country. Most girls who marry early drop out of school and often have early, high-risk pregnancies. Child brides are also at risk of abuse, exploitation, and separation from relatives and friends.
Sporadic
When a disease occurs infrequently and irregularly
Endemic
When a disease maintains a constant presence in a population within a geographic area
Epidemic
When there is an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area.
Pandemic
When an epidemic has spread over several countries or continents, usually affecting a large number of people.
Vectored Disease
A disease spread by a vector; vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans.
Dependency Ratio
The ratio of the number of dependents (0 to 14 and 65+) to the total working-age population (15-64) in a country or region; a higher number indicates a greater burden on the working-age population
