Urban regeneration occurs if young people, adults and the elderly live in a living, cohesive and mutually supportive community. Action is needed at different levels: map bodies/associations present in each city; establish an intergenerational hub that creates a network between bodies with similar interests (which often ignore the existence of the other) and then connects associations for young people with those for the elderly; include people with a migrant background in the community to create cohesion and social development; create an EU platform that collects case studies of intergenerational inclusion, then create formats with the best. Young seniors +65 become mentors of young adults 15-29, the latter discover their own interests and turn them into work/study (NEETs decrease), the elderly receive digital help and in daily life; University students and seniors cohabit: decreases ageism; Increases lifelong learning; housing accessible to students. Young people stay in their countries of origin, create a family where the community is alive and the cost of living is adequate. Digitalization allows remote working. Childcare, care and inclusion services for people with disabilities are available: Births are increasing. The elderly do not make up for the inefficiencies of public social service. Decreases racism: Immigrants are part of the community. Schooling increases and brain drain decreases. Everyone feels responsible
