Fertility in Congo

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 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: Nigeria 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.
