Ilfov County () 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.
The county has experienced rapid demographic growth in the 21st century, being the fastest growing Romanian county between 2011 and 2021.
Ilfov County had a population of 542,686 at the 2021 Romanian census.
The population density is 342.82 per km<sup>2</sup>. 40% of the population commutes and works in Bucharest, although, in recent years, many industrial plants were built outside Bucharest, in Ilfov county. It has an annual growth of about 4%.
The county has an area of 1,584 km<sup>2</sup> and it is situated in the Romanian Plain between the ArgeÃÂ River and the IalomiÃÂa River. The county is the smallest by area in Romania.
The main rivers that pass through the county are: DâmboviÃÂa River, Colentina River and Gruiu River. Several lakes can be found in Ilfov county, notably Lake Cernica, Lake Snagov and Lake CÃÂldÃÂruÃÂani.
The base occupation used to be agriculture. Nowadays, due to the economical growth in Bucharest, many companies have opened their offices, production facilities or warehouses in the nearby villages, situated in the Ilfov County, thus making it the most developed county in Romania.
The predominant industries in the county are:
At Otopeni there is the main aerial transport hub in Romania - the Henri CoandÃÂ International Airport. Also all the main roads and railways leaving Bucharest pass through the county.

Most of today's Ilfov County used to be covered by Codrii VlÃÂsiei, a thick forest, but there were several Dacian settlements, most important being Argedava, on the right bank of the ArgeÃÂ River in what is now PopeÃÂti, which was the capital of king Burebista.
The thick forests were useful for retreat during the Migration Age because they were not easy to cross on horseback. In fact, the name of the forest means "the Forests of the Vlachs", a name given by the Slavs who inhabited the nearby plains.
The county was named after the Ilfov River and it appears for the first time in a 1482 donation act of voivode Vlad CÃÂlugÃÂrul to the monastery of Snagov. In earliest documents, it was known as Elhov. The name is of Slavic origin (', alder; ', possessive suffix), referring to a river which flowed through an alder forest.
The county has 8 towns and 32 communes. The largest settlements by population are PopeÃÂti-Leordeni, Voluntari, Chiajna, Bragadiru, Pantelimon, Buftea, Otopeni. These are the only settlements with more than 20,000 residents. Unlike most other areas of Romania, the population in Ilfov County is increasing, as many of the settlements here are seen as suburbs of Bucharest and are increasingly attracting upper-class families. At the 2022 census, 45.19% of the county's population was defined as urban.
PopeÃÂti-Leordeni is the largest settlement in Ilfov county, with a population of 53,431 at the 2021 census (representing an increase of 31,536 people since 2011, this being the largest population increase of any settlement in Romania between 2011 and 2021).
Voluntari is the second largest settlement, with a population of 47,366 at the 2021 census. It has experienced rapid population growth in recent years. There were serious debates about the city level being awarded to Voluntari in 2004, as it is alleged that it was given in regard to the city's political affiliation, rather than population, development or any other objective features. Despite this, Voluntari did have a population of 30,000 at that time, and many other localities with this population have been given city status in the past.
Chiajna is the third largest settlement in Ilfov county, and one of the fastest growing localities in Romania, with its population having increased from 29,329 people in 2011 to 43,588 people in 2022, according to the Romanian population census.
Buftea is associated with the cinema of Romania; as the film studios MediaPro Pictures are located in Buftea.
Otopeni was transformed into a town under the communist regime, as part of Nicolae CeauÃÂescu's systematisation policy, with semidetached houses being replaced by four-storey blocks of flats.
Before 1972, Ilfov County used to be one of the largest counties of Romania, but parts of it were added to neighbouring counties and nowadays it is the smallest (excluding the city of Bucharest, which has special status). Between 1981 and 1997, it was called "Sectorul Agricol Ilfov" and it was not a separate county, but subordinate to the capital.
Ilfov County is the only county that has its capital outside of its territorial area, in Bucharest, which is not part of the actual county. Initially, right after the 1968 reform of the public administration in communist Romania, Ilfov was a larger county, that comprised its present-day territory, the entire Giurgiu County, Bucharest and the western parts of CÃÂlÃÂraÃÂi and IalomiÃÂa counties. Later during the communist period, its territory was reduced to its current size and it became one of the sectors of Bucharest. It became again a county in 1997, when its capital was designated to be Bucharest. However, in 2005, some plans were proposed that would merge Bucharest with 90 other communes located to up to 40 km outside the city, in Ilfov County and other nearby counties into a "metropolitan area" of Bucharest, similar to Greater London. As of 2011, these plans did not happen, while a debate on the general administrative division of Romania was under way.
Historically, the county was located in the southern part of Greater Romania, in the southern part of the historical region of Muntenia, around and in the south of Bucharest. During the interwar years, the county, which contained the city of Bucharest, was the most populous county in Romania. Currently the territory of the county is divided among Bucharest, the current Ilfov County, DâmboviÃÂa County, IalomiÃÂa County, CÃÂlÃÂraÃÂi County, and Giurgiu County. It was bordered to the north by the counties of Prahova and Dâmbovià £a, to the west by VlaÃÂca County, to the east by IalomiÃÂa County, and to the south by Durostor County.
The county included the cities of Bucharest and OlteniÃÂa, and originally seven administrative districts (plÃÂÃÂi):
Subsequently, the county established three more districts:<ol start="8"> <li>Plasa Buftea, headquartered at Buftea (with 50 villages)</li> <li>Plasa DomneÃÂti, headquartered at DomneÃÂti (with 44 villages)</li> <li>Plasa Pantelimon, headquartered at Pantelimon (with 43 villages)</li> </ol>
