In European cities, one resident in two is aged 40 or older. The proportion of one-person households is higher than the proportion of families. Collective dwellings predominate, especially in larger cities. On average, 30% of households in European cities are tenants of private housing, and 12% of social housing. Overall, people primarily use their cars to get to work, even if public transport is used more when the density of the city is greater. The relative situation of cities in terms of income is quite variable from one country to another. This is also the case for crime, measured here by the murder rate. French cities, by comparison, tend to be young with a median age of 38 years. Dwellings are slightly larger per person than the European average. This is also the case in Germany. Environmentally-friendly modes of transport are used relatively little. The income gap between cities is rather more marked than elsewhere. Finally, with an average murder rate of 0.13 for 10,000 inhabitants, French cities are on average safer than European cities.
