[Measuring the impact of an "age-friendly city" approach on a territory by setting up cross-cutting indicators].

The "Age-friendly cities" program has been developing in France since 2010. So far the existing protocols had not allowed cities to assess actions taken in favor of elderly people comprehensively. The work done with the Francophone network of age-friendly cities (RFVAA) has led to the definition of an indicator consisting of 12 points; the relative importance of each target was weighted using a decision-making tool.
