Children and young people are affected by many projects in their city. According to the municipal code in Rhineland-Palatinate, adolescents must be involved—and children should be involved—in all matters that concern them. The Mainz City Council also supports the participation of young people. That is why, whenever possible, children and adolescents are directly involved in all citizen participation initiatives in Mainz.

At every meeting of the Youth Welfare Committee, children and adolescents are given the floor at
5:00 p.m. This gives them the opportunity to ask committee members questions, offer suggestions, or voice criticism regarding any issues that concern them.

Since 2022, a youth conference for up to 300 young people between the ages of 13 and 17 has been held once a year. In the morning, the young people gather their suggestions for improvements in Mainz and develop their own project ideas. At noon, they present their projects to representatives from city politics, city administration, and other institutions. The projects are to be implemented together with the young people within a year.

When playgrounds are newly built or redesigned in Mainz, all interested children and young people are asked for their opinion. They can submit suggestions for playground equipment and vote for their favorite option.

The "Jugend in Mainz" website provides information about other opportunities to get involved offered by clubs and organizations outside the state capital of Mainz. It also features a wealth of additional information for children and teens in Mainz, such as children’s, youth, and cultural centers, events, school social work, and more.
