Mercer Human Resource Consulting issues yearly a global ranking of the world's most livable cities based on 39 key quality-of-life issues. Among them: political stability, currency-exchange regulations, political and media censorship, school quality, housing, the environment, and public safety. Mercer collects data worldwide, in 215 cities. The difficult situation of the quality of life in Bucharest is confirmed also by a vast urbanism study, done by the Ion Mincu University of Architecture and Urbanism.
