Baghdad has been named the city with the lowest quality of living in Mercer's 19th annual Quality of Living survey, beating out Bangui in the Central African Republic and Sana'a in Yemen. The survey takes into account a city's infrastructure, transport connections, economic stability, social unrest and growing political upheaval – all of which affect the quality of living.

Ilya Bonic, senior partner and president of Mercer's Career business, stated that all of these issues add to the "complex challenge multinational companies face when analysing quality of living for their expatriate workforce". He explained that "for multinationals and governments it is vital to have quality of living information that is accurate, detailed, and reliable".
