At the end of 2019, the result of the Algerian population census has been of 43 900 000 million inhabitants. The demography growth knows a favorable development, with a clear trend to fall since these twenty last years, the rate moving from 3.21% during the years 1966-1977 to 1.71 during the years 1998-2008. The last 30 years, life expectancy has increased of almost twenty years, approaching the seventy three years old since 2006. The infant mortality rate, which exceeded 15 % in 1970, has decreased of 2/3. Fecundity index moved from 8.3 children per woman in 1970 to 2.54 children per woman in 2004, especially because of the late marriages added to the gradual generalization of contraception practices.

This evolution allows making a projection counting on about 40 million in the year 2020.
This population remains very young. Almost half of it is less than 19 years old, (48.24). The third of the population is less than 15 years old, and those over 65 years old represent barely 5% of the total.

Space distribution of the population is almost of 40% on the littoral, that’s to say a little more than 12 million on 5% of the territory, so an average density of 245 inhabitants to the square kilometer (km2) This concentration is mainly due to the climate and to the nature of the territory relieves.
