This is especially true for Healthy life expectancy, the definition of which criteria may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years; however, this number decreases to 75.5 years for Indigenous people in the country. [4]
The annual population growth rate is estimated at 0.13% [2] According to the 2022 revision of the World Population Prospects [3] [4] the total population was 2,281,454 in 2021, compared to only 734 000 in 1950. The proportion of children below the age of 15 in 2010 was 37.4%, 58.3% was between 15 and 65 years of age, while 4.3% was 65 years or ...
The country is among the "Low Human Development" countries (rank 160 of 187 on the Human Development Index as classified by UNDP), with 52 years of life expectancy for men and women, estimated in 2009.

Human population projections are attempts to extrapolate how human populations will change in the future. [2] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [3] Models of population growth take trends in human development and apply projections into the future. [4]
