  As per the 2021 census, 1,716,961 inhabitants lived within the city limits, a decrease from the figure recorded at the 2011 census. This decrease is due to low natural increase, but also to a shift in population from the city itself to its smaller satellite towns such as Popești-Leordeni, Voluntari, Chiajna, Bragadiru, Pantelimon, Buftea and Otopeni. In a study published by the United Nations, Bucharest placed 19th among 28 cities that recorded sharp declines in population from 1990 to the mid-2010s. In particular, the population fell by 3.77%.
  
  The city's population, according to the 2002 census, was 1,926,334 inhabitants, or 8.9% of the total population of Romania. A significant number of people commute to the city every day, mostly from the surrounding Ilfov County, but official statistics regarding their numbers do not exist.
  
  Bucharest's population experienced two phases of rapid growth, the first beginning in the late 19th century when the city was consolidated as the national capital and lasting until the Second World War, and the second during the Ceaușescu years (1965–1989), when a massive urbanization campaign was launched and many people migrated from rural areas to the capital. At this time, due to Ceaușescu's decision to ban abortion and contraception, natural increase was also significant.
  
  Bucharest is a city of high population density: 8,260/km 2 (21,400/sq mi), as most of the population lives in high-density communist era apartment blocks (blocuri). However, this also depends on the part of the city: the southern boroughs have a higher density than the northern ones. Of the European Union country capital-cities, only Paris and Athens have a higher population density (see List of European Union cities proper by population density). In addition to blocks of flats built during the communist era, there are also older interwar ones, as well as newer ones built in the 1990s and in the 21st century. Although apartment buildings are strongly associated with the communist era, such housing schemes were first introduced in Bucharest in the 1920s.
  
  About 97.3% of the population of Bucharest for whom data are available is Romanian. Other significant ethnic groups are Romani, Hungarians, Turks, Jews, Germans (mostly Regat Germans), Chinese, Russians, Ukrainians, and Italians. A relatively small number of Bucharesters are also Greeks, Armenians, Kurds, Bulgarians, Albanians, Poles, French, Arabs, Africans (including the Afro-Romanians), Iranians, Vietnamese, Filipinos, Nepalis, Afghans, Sri Lankans, Bangladeshis, Pakistanis, and Indians. 226,943 people did not declare their ethnicity.
  
  In terms of religious affiliation, 96.1% of the population for whom data are available is Romanian Orthodox, 1.2% is Roman Catholic, 0.5% is Muslim, and 0.4% is Romanian Greek Catholic. Despite this, only 18% of the population, of any religion, attends a place of worship once a week or more. The life expectancy of residents of Bucharest in 2015 was 77.8 years old, which is 2.4 years above the national average.
