indicated and half are younger than the median age. This parameter provides an indication of age distribution.

Density (P/Km²): Population Density is a measurement of population per unit area, or exceptionally per unit volume. It is the quantity of type number density. Population Density is measured in population per square kilometre (Km²).
Urban Population: Urban population refers to the population inhabiting areas that have a greater population density than rural areas and are overall more compact than rural areas.
Urban Population %: Urban population as a percentage of total population.
Country’s Share of World Pop: Total population in the country is measured as a percentage of total World Population as of July 1 of the year indicated.
World Population: Total World Population as of July 1 of the year indicated.
