One concept which measures the world's largest cities is that of the metropolitan area, based on the concept of a labor market area and is defined as an employment core and the surrounding areas that have strong commuting ties to the core. There is no accepted, globally consistent definition of what constitutes a metropolitan area, thus making comparisons between cities in different countries difficult. However, for consistency, the sources on this article include official figures from governments only; as an alternative to the metropolitan area, Eurostat introduced the concept of the Larger Urban Zone in 2004. OECD defines Functional Urban Areas for cities in OECD countries. Both Larger Urban Zone and Functional Urban Area define a city as an urban core surrounded by a commuting zone, so are similar to the general concept of the "metropolitan area". Eurostat only computes Larger Urban Zone populations for European Union member states, candidate members, European Free Trade Area members. OECD computes Functional Urban Area populations for OECD member states.
These two statistics are therefore not available for most developing countries.

The Lac Sept Îles is a waterbody located in the township of Gosford, in the municipality of Saint-Raymond, in the Portneuf Regional County Municipality, in the administrative region of Capitale-Nationale, in Quebec, in Canada. Thanks to its forest and mountain environment, its islands and bays, its proximity to the Quebec and the Duchesnay tourist resort, the resort is developed around the lake. A road surrounds the lake to serve residents and vacationers. Vacationing at Sept Îles Lake dates back to 1857-58, compared to 1896 at Sergent Lake; the Lake Sept Îles is located 6 km northeast of the village center of Saint-Raymond, in Portneuf Regional County Municipality. Lake Sespt-Îles is supplied by three tributaries: north-west: the Gosford River flowing mountains 5.7 km south-west (parallel to the Sainte-Anne River, to flow to the bottom a narrow bay which ends at the mouth of Lac des Aulnaies, separated from Lac Sept Îles by a bridge. Lac au Chien itself is fed by Lac à la Perche, Lac du Ventre Rouge, Lac des Roches, Lac Maher and Lac aux Deux Truites.
Lake Sept-Îles is surrounded by mountain peaks that reach: north: between 397 m and 533 m, south-east: between 267 m and 381 m, south: between 349 m and 372 m, west: 254 m and 335 m. The lake has several bays including Vachon Bay; the mouth of the lake is located southwest of the lake. The outlet of the lake is the Portneuf River which flows southwest to the town of Portneuf where its waters flow into the St. Lawrence River; the lake is aptly named because it has seven islands, three islands and four islets. Colonization around the lake began around 1857-1858. During the XXth, the perimeter of the lake was fitted out with numerous chalets; the island of Genois, the largest and not accessible by road, has around twenty homes. The other islands contain some hambitations; the toponym “Lac Sept Îles” was formalized on December 5, 1968 at the Bank of Place Names of the Commission de toponymie du Québec.
