Article: According to the Namibia Labour Force Survey Report 2012, conducted by the Namibia Statistics Agency, the country's unemployment rate is 27.4%. "Strict unemployment" (people actively seeking a full-time job) stood at 20.2% in 2000, 21.9% in 2004 and spiraled to 29.4% in 2008. Under a broader definition (including people that have given up searching for employment) unemployment rose to 36.7% in 2004. This estimate considers people in the informal economy as employed. Labour and Social Welfare Minister Immanuel Ngatjizeko praised the 2008 study as "by far superior in scope and quality to any that has been available previously", but its methodology has also received criticism.
