Other urban areas 5- The main municipalities of secondary agglomerations Main municipalities of moderately dense agglomerations which do not belong to the urban unit of Paris of 2008 (in the INSEE sense) with a human density at least equal to 30 individuals at hectare and human activity (population + employment in 2016) greater than or equal to 5,000 individuals.6- Other municipalities in secondary agglomerations Other agglomeration municipalities which do not belong to the urban unit of Paris of 2008. Rural space 7- Rural municipalities All of the remaining municipalities constitute the rural area.
