Paris is the capital and most populous city of France, with an estimated population of 2,175,601 residents as of 2018, in an area of more than 105 square kilometres . Since the 17th century, Paris has been one of Europe's major centres of finance, diplomacy, commerce, fashion, gastronomy, science, and arts. The City of Paris is the centre and seat of government of the region and province of Île-de-France, or Paris Region, which has an estimated population of 12,174,880, or about 18 percent of the population of France as of 2017. The Paris Region had a GDP of €709 billion in 2017. According to the Economist Intelligence Unit Worldwide Cost of Living Survey in 2018, Paris was the second most expensive city in the world, after Singapore and ahead of Zürich, Hong Kong, Oslo, and Geneva. Another source ranked Paris as most expensive, on par with Singapore and Hong Kong, in 2018.
The official estimated population of the City of Paris was 2,206,488 as of 1 January 2019, according to the INSEE, the official French statistical agency. This is a decline of 59,648 from 2015, close to the total population of the 5th arrondissement. Despite the drop, Paris remains the most densely-populated city in Europe, with 252 residents per hectare, not counting parks. This drop was attributed partly to a lower birth rate, the departure of middle-class residents and the possible loss of housing in the city due to short-term rentals for tourism.
The centre of Paris contains the most visited monuments in the city, including the Notre Dame Cathedral and the Louvre as well as the Sainte-Chapelle; Les Invalides, where the tomb of Napoleon is located, and the Eiffel Tower are located on the Left Bank south-west of the centre. The Panthéon and the Catacombs of Paris are also located on the Left Bank of the Seine. The banks of the Seine from the Pont de Sully to the Pont d'Iéna have been listed as a UNESCO World Heritage Site since 1991.

Domestically, air travel between Paris and some of France's largest cities such as Lyon, Marseille, or Strasbourg has been in a large measure replaced by high-speed rail due to the opening of several high-speed TGV rail lines from the 1980s. For example, after the LGV Méditerranée opened in 2001, air traffic between Paris and Marseille declined from 2,976,793 passengers in 2000 to 1,502,196 passengers in 2014. After the LGV Est opened in 2007, air traffic between Paris and Strasbourg declined from 1,006,327 passengers in 2006 to 157,207 passengers in 2014.

Every July, the Tour de France bicycle race finishes on the Avenue des Champs-Élysées in Paris.
The population of Paris today is lower than its historical peak of 2.9 million in 1921. The principal reasons were a significant decline in household size, and a dramatic migration of residents to the suburbs between 1962 and 1975. Factors in the migration included de-industrialisation, high rent, the gentrification of many inner quarters, the transformation of living space into offices, and greater affluence among working families. The city's population loss came to a temporary halt at the beginning of the 21st century; the population increased from 2,125,246 in 1999 to 2,240,621 in 2012, before declining again slightly in 2017. It declined again in 2018.
