Step-by-step explanation:
The new towns in Europe that are referred to in the question are a result of the so-called "New towns movement", which consists of a program planned and executed by European governments as an effort to remedy overcrowding and congestion in large, industrialized cities (such as London). This plan took place after World War II, and it provided settlement for scattered citizens after the conflict.
Citizens who were benefited by the New towns movement were put back to economic stability thanks to their new free-of-charge homes.
