The population stood at 37 900 00 inhabitants 1 (29 276 767 inhabitants according to the general population and housing census of 1998). from a rate of natural increase (rnI) standpoint, demographic growth is following a favorable evolution, as a net downward trend has been observed over the past twenty years (the rate went from 3.14% between 1971 and 1975 to about 1.44% between 1999 and 2005).
Important changes have taken place with regard to principal characteristics. life expectancy increased by nearly twenty years over the past thirty years, approaching 75.7 years in 2008. The infant mortality rate, which was above 15% in 1970, went down by two thirds. The fertility index dropped noticeably, going from 8.3 children per woman in 1970 to 2.54 children per woman in 2006, under the combined effect of the lower rate of marriage and a noticeable spread of the use of contraception.
The demographic situation in 2012 is marked by a significant increase in the volume of births (978,000), a growth of 7.5% compared to 2011, the volume of deaths continues its growth to reach 170,000 deaths, while marriages volume recorded a slight rise compared to what was observed in 2011.
The projections for the Algerian population until 2100 mainly highlight a strong demographic and fertility rates deceleration, also an aging population and an increased life expectancy. The population is expected to increase by 18% between 2013 and 2025, and by a further 17% between 2025 and 2050, and only to 0.7% between 2050 (population 54.9 million) and 2100 (54.5 million inhabitants).
nearly 40% of the population lives on the coastline. More than 14 million people live in the Tell region in the north with an average density of 260 inhabitants per km2. This density drops to less than 1 inhabitant per km2 in the Great South region, for a national average of 13 inhabitants per km2. Along the coastline, the population tends to be concentrated around the major towns. While the urban sector only accounted for 12% of Algeria’s population in 1960, it represented more than 60% of the population in 2009. The urban population is eleven times larger than it was four decades ago.
