In three and a half years, from March 2017 to October 2020, changes in the number of shops and services were minimal (1,164). This figure is the visible part of the 16,700 modifications that took place in the form of changes of business sectors, signs, creations, disappearances and the transformation of shops and services into other types of premises (vacant, offices, health activities…). Only the latter 3 types of changes are shown on the map. The blue circles indicate a rise and the red circles a fall in the number of commercial activities at any given address. An identical number of shops or services at an address over the two reference years is shown in grey.
