Ilfov (Romanian pronunciation: [ˈilfov]) is the county that surrounds Bucharest, the capital of Romania. It used to be largely rural, but, after the fall of communism, many of the county's villages and communes developed into high-income commuter towns, which act like suburbs or satellites of Bucharest. The gentrification of the county is continuing, with many towns in Ilfov, such as Otopeni, having some of the highest GDP per capita levels in the country.
