Une mesure de l'étalement urbain en France, 1982-90

Abstract : In order to measure urban sprawl, we propose two new concepts: the median distance and the "ninetyan" distance. The median distance is the radius of the circle around the center which includes half of the zone's population. The "ninetyan" distance is the radius of the circle around the center which includes ninety percent of the zone's population. By applying these concepts to the 200 major French agglomerations, we show that the median distance is not related to the city's population. The ninetyan distance varies greatly from one city to another, but tends to increase with city population. Between 1982 and 1999, the growth of cities with a population under half a million was mainly located in the ring between median and ninetyan distances, whereas major cities continued to increase their sprawl.
