Peri-urban growth in France in the past 45 years: extension and densification
In the past four decades, the peri-urban rings around French cities have become wider and denser. The Paris Region (Île-de-France) was the forerunner, having displayed both trends as far back as the late 1960s. In most regions, the spatial extension of cities was particularly significant in the early 1970s. It preceded the peak phase of densification of peri-urban rings in the late 1970s and early 1980s. In the past ten years, peri-urbanisation has resumed at paces that vary from region to region. Some farming or natural areas in urban peripheries are turning into so-called artificial areas, mainly as a result of the construction of single-family homes.
