Where local government are responsible for a greater share of own source revenues, they face a distinct pressures to increase their local tax bases. Depending on the nature of local taxation, this can lead to a push for residential expansion in order to increase the amount of property taxes available to a municipality, or attracting businesses to the area in order to increase business tax contributions. Both Nantes and Saint-Nazaire are increasingly relying on own source revenues to fund operating expenditures. In Nantes, the contribution of local taxes to total operating expenditures between 2009 and 2014 increased by 16% while in Saint-Nazaire it increased by 22% (Figure 3.9).
