Population Pyramid for the World

A Population Pyramid is a pair of histograms indicating the distribution of the population among the different age groups and sexes (males on the left and females on the right). The shape of a Population Pyramid can help understand growth patterns and possible dependency issues or gender imbalances. A pyramid with a wide base and narrow top suggests high fertility and a growing population, whereas a pyramid with a narrow base suggests an ageing population with low fertility rates. Compare pyramids over time from 1960 to 2080 (based on United Nations Population projections). More on Population Pyramids.

Median Age

The median age in the World is 29.8 years (2019).

World Dependency Ratio

The age dependency ratio expresses the relationship between the "dependent population" (ages 0-15 and 65-plus, referred as "youth" and "elderly") and the "working age population" (ages 16-64). Higher values indicate a greater level of dependency. See also: definition and formula.

Fertility in the World

A Total Fertility Rate (TFR) of 2.1 represents the Replacement-Level Fertility: the average number of children per woman needed for each generation to exactly replace itself without needing international immigration. A value below 2.1 will cause the native population to decline

Population Density

The 2019 population density in the World is 52 people per Km2 (134 people per mi2), calculated on a total land area of 148,940,000 Km2 (57,506,032 sq. miles).

Definitions

Population Pyramid

A Population pyramid (also called "Age-Sex Pyramid") is a graphical representation of the age and sex of a population.

Types:

  • Expansive - pyramid with a wide base (larger percentage of people in younger age groups, indicating high birth rates and high fertility rates) and narrow top (high death rate and lower life expectancies). It suggests a growing population. Example: Nigera Population Pyramid
  • Constrictive - pyramid with a narrow base (lower percentage of younger people, indicating declining birth rates with each succeeding age group getting smaller than the previous one). Example: United States
  • Stationary - with a somewhat equal proportion of the population in each age group. The population is stable, neither increasing nor decreasing.

Stages:

 

Dependency Ratio

There are three types of age dependency ratio: Youth, Elderly, and Total. All three ratios are commonly multiplied by 100.

Youth Dependency Ratio
Definition: population ages 0-15 divided by the population ages 16-64.
Formula: ([Population ages 0-15] ÷ [Population ages 16-64]) × 100

Elderly dependency ratio
Definition: population ages 65-plus divided by the population ages 16-64.
Formula: ([Population ages 65-plus] ÷ [Population ages 16-64]) × 100

Total dependency ratio
Definition: sum of the youth and old-age ratios.
Formula: (([Population ages 0-15] + [Population ages 65-plus]) ÷ [Population ages 16-64]) × 100

NOTE: Dependency Ratio does not take into account labor force participation rates by age group. Some portion of the population counted as "working age" may actually be unemployed or not in the labor force whereas some portion of the "dependent" population may be employed and not necessarily economically dependent.
