Ilfov 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.

Bucharest is the capital and largest city of Romania. The metropolis stands on the River Dâmbovița in south-eastern Romania. Its population is officially estimated at 1.76 million residents within a greater metropolitan area of 2.3 million residents, which makes Bucharest the 8th most-populous city in the European Union. The city area measures 240 km2 and comprises 6 districts (Sectoare), while the metropolitan area covers 1,811 km2. Bucharest is a beta global city, a major cultural, political and economic hub, and the country's seat of government.
