Fertility in Sierra Leone
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
TOTAL FERTILIY RATE (TFR) 4.3 (Live Births per Woman, 2020)

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.
- 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).
- 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.
