Historical population
YearPop.±% p.a.

People from Seine-et-Marne are known as the Seine-et-Marnais.

Originally Seine-et-Marne was very rural and lightly populated. Over the past 50 years, however, its population has tripled, due to the development of the Paris conurbation and the building of new towns in the northwest of the region. The population was estimated to be 1,267,496 inhabitants in 2006. The region has changed from consisting only of small villages to forming a large part of the Paris conurbation.

Seine-et-Marne as a whole shares a sister city relationship with Orlando, Florida, United States, as both host Disney theme parks.

1 This group is made up largely of former French settlers, such as Pieds-Noirs in Northwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), as well as to a lesser extent foreign-born children of French expatriates. Note that a foreign country is understood as a country not part of France in 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics.

2 An immigrant is a person born in a foreign country not having French citizenship at birth. Note that an immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.


With 60 percent of the region used as farmland, Seine-et-Marne is where most agricultural activity occurs within Île-de-France. Cereals and sugar beet are the principal exports from Seine-et-Marne.

The other key industrial structures are the refinery at Grandpuits and the Safran Aircraft Engines research plant at Villaroche. The new town of Marne-la-Vallée is the centre of tourism in Seine-et-Marne in terms of number of visitors, mainly due to the Disneyland Park and Walt Disney Studios Park theme parks at Disneyland Paris.
