In Luanda, renting a luxury two-bedroom unfurnished apartment costs an average of $7,000 per month, compared to $4,300 in New York, $3,345 in Shanghai, $2,456 in Rome and $1,800 in Buenos Aires.
"In Luanda, accommodation costs are very, very high," explained Mercer senior associate Nathalie Constantin-Metral.
The high cost of living in Luanda and N'Djamena is also down to the fact that expats shop differently to locals. Expats tend to look for international brands they are used to at home, which have to be imported. A club sandwich and soda meal costs $20.38 in Luanda, compared to $6.29 for a fast-food meal in New York and $3.57 in Shanghai. Angola's oil reserves do at least mean that gas is cheap in Luanda -- 59 cents per liter, compared to 87 cents in New York and $1.12 in Shanghai.
In recent years Angola has been attracting expats with its growing economy, driven by oil production. It produces up to 1.9 million barrels a day, with oil contributing about 85% of its GDP, according to the CIA World Factbook.
Despite its oil, the vast majority of Angolans work in agriculture and more than a third live below the poverty line, according to the U.N. Development Program.
