The Paris metropolitan area (French: aire urbaine de Paris, pronounced: ) is a statistical area that describes the reach of commuter movement to and from Paris and its surrounding suburbs. Created by France's national statistical office INSEE to describe suburban development around centres of urban growth, the aire urbaine is composed of a couronne périurbaine (or "rim" ) surrounding a more densely built and densely populated pôle urbain (or "urban cluster"), also known as unité urbaine ("urban area"). As of 2010 the Paris metropolitan area, with its 17,174 km² (6,631 sq mi), extends significantly beyond Paris' administrative Île-de-France region, a region also commonly referred to as the région parisienne ("Paris Region"). It had a population of 12,292,895 inhabitants at the January 2011 census, making it the second largest urban region in Europe after that of London. Nearly 19% of France's population resides in the region.
The Paris metropolitan area expands at each population census due to the rapid population growth in the Paris area: new communes (municipalities) surrounding Paris are included when they meet the 40% commuter threshold required. At the 1968 census, the earliest date for which population figures were retrospectively computed for French aire urbaines, the Paris metropolitan area had 8,368,459 inhabitants in an area that only encompassed central Île-de-France. At the 1999 census the Paris metropolitan area was by then slightly larger than Île-de-France and had 11,174,743 inhabitants in 14,518 km². At the 2011 census it had reached 12,292,895 inhabitants in 17,174 km², an area significantly larger than Île-de-France.
