Algiers is situated on the west side of a bay of the Mediterranean Sea. The modern part of the city is built on the level ground by the seashore; the old part, the ancient city of the deys, climbs the steep hill behind the modern town and is crowned by the casbah or citadel, 122 metres above the sea. Algiers is built on the slopes of the Sahel Hills, which parallel the Mediterranean Sea coast, and it extends for some 10 miles along the Bay of Algiers. The city faces east and north and forms a large amphitheatre of dazzling white buildings that dominate the harbour and the bay.

Algeria’s economy is dominated by its export trade in petroleum and natural gas, commodities that, despite fluctuations in world prices, annually contribute roughly one-third of the country’s gross domestic product . Until 1962 the economy was based largely on agriculture and complemented France’s economy. Since then the extraction and production of hydrocarbons have been the most important activity and have facilitated rapid industrialization. The Algerian government instituted a centrally planned economy within a state socialist system in the first two decades after independence, nationalizing major industries and implementing multiyear economic plans. However, since the early 1980s the focus has shifted toward privatization, and Algeria’s socialist direction has been modified somewhat. Standards of living have risen to those of an intermediately developed country, but food production has fallen well below the level of self-sufficiency.

Algiers is an important economic, commercial and financial center, with in particular a stock exchange with a capitalisation of 60 million euros. The city has the highest cost of living of any city in North Africa, as well as the 50th highest worldwide, as of March 2007, having gained one position compared to the previous year.

Mohamed Ben Ali El Abbar, president of the Council of Administration of the Emirate Group EMAAR, presented five «megaprojects» to Algerian President Abdelaziz Bouteflika, during a ceremony which took place Saturday, July 15, within the Palace of the People of Algiers. A shopping centre and three high-rise office buildings rising with the top of the commercial zone will accompany the project.

The second project will not relate to the bay of Algiers and aims to revitalize the sea front. The development of the 44 km seafront will include marinas, channels, luxury hotels, offices, apartments of great standing, luxury stores and leisure amenities. A crescent-shaped peninsula will be set up on the open sea. The project of the bay of Algiers will also comprise six small islands, of which four of round form, connected to each other by bridges and marinas and will include tourist and residential complexes.

The third project will relate to restructuring an area of Algiers, qualified by the originators of the project of “city of wellness”. El Abbar indicated to the journalists that the complex would be “agreeable for all those which will want to combine tourism and well-being or tourism and relaxation”. The complex will include a university, a research center and a medical centre. This 90 hectares site will include shopping centres, residential zones with high standard apartments and a golf course surrounded by villas and hotels. Two other residential zones, including 1.800 apartments and 40 high standard villas, will be built on the surrounding hills.

The fifth project is that of the tourist complex Colonel Abbès, which will be located 25 km west from Algiers. This complex will include several retail zones, meeting places, and residential zones composed of apartments and villas with views of the sea. Currently there is another project under construction, by the name of Algiers Medina. The first step of the project is nearly complete.

Commercial services, industrial, construction, and public works continue to drive non-hydrocarbon growth. Exports of goods and services contracted in real terms by 6.4 percent in Q1-2019, driven by a decline in hydrocarbon exports due to rising domestic demand and stagnant production. At the same time, the import of goods and services has increased by 4.1 percent despite the slowdown in the economy which has resulted in a wider trade and account deficit. Inflation remained stable at 4.3 percent in 2018 and has declined at 4.3 percent in 2018 and has declined to 4.1 percent in end-March 2019.

The unemployment rate reached 11.7 percent as of October 2018 and is higher among the youth , women and university graduates as a result of the skills mismatch in the labor market. There are no recent poverty estimates for the country, but official numbers from 2010/2011 show that 5.5 percent of the population was considered poor, with large regional variations and higher concentration in the Sahara and the Steppe regions.
