ALGIERS - The number of Algerians working in the informal sector has more than doubled in the past decade, rising to 3.9 million in 2010 from 1.6 million in 2001, the national statistics office (ONS) said on Monday.
"Informal work outside the farming sector in 2010 employed an estimated 3.9 million people who say they are not affiliated to social security, which constitutes 45.6 percent of the non-agricultural workforce," APS news agency said, citing an ONS report.
According to the report, 45.3 percent of informal employment is generated by the trade and services sector, 37.4 percent by the building and public works sector and 17.3 percent by industry.
The report did not mention how much undeclared labour exists in the agricultural industry, the economic sector most affected by informal employment in Algeria.
Unemployment among young Algerians, who account for the majority of the country's 37 million inhabitants, stands at 21 percent, according to the International Monetary Fund.
