It's the same everywhere, as most European cities are dominated by 20-35yo people. They vote for green parties and then move out when they have children, as they realize that the policies they supported are not child- or family-friendly at all. The extreme example is Seoul, with its zones where kids are forbidden. It's a shame, as families require more public services and infrastructure (hospitals, schools, playgrounds, swimming pools, and so on), but they are being pushed away by childless youngsters who hate cars. Unfortunately, no middle ground seems acceptable for this crowd, so I'm unconvinced that it will change.
Another negative aspect is that cyclists do not use public transportation, so they lead municipalities to decrease investment in this sector, which is, however, the most inclusive, safe and efficient way to move people around. This is also seen in Paris, where the bus speed has never been so slow, the fleet is aging,, while the city hall spends like a teenager on a weekend trip with daddy's credit card on new bike lanes.
In the EU at least, the next nail in the coffin will be the low-emissions zones that will make it prohibitively expensive to enter/leave the center, forcing families to leave metropolises altogether.
