The land area of this arrondissement is 16.324 km2 (6.303 sq. miles, or 4,034 acres), two-thirds of which consists of the Bois de Vincennes park. Excluding the Bois de Vincennes, its land area is 6.377 km2 (2.462 sq. miles, or 1,576 acres).
The peak of population of Paris's 12th arrondissement occurred in 1962 and was followed by three decades of decline. Recently, however, the population has begun to grow again, since the restructuring of the 1990s. As of the last census, in 1999, the population was 136,591 inhabitants. The same census showed that the 12th arrondissement, heavily involved in business activity, contained 112,336 jobs, mainly around the new district of Bercy.
¹This 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), and to a lesser extent foreign-born children of French expatriates. Note that a foreign country is understood as a country not part of France as of 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.
²An 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.
