This was the first mass-produced suburb in the united states

The correct answer is Levittown.

Explanation:

Levittown is the first major suburb that served as a model for the next suburbs generated after the war.

It is a village located in the city of Hempstead in New York and was created by Abraham Levit, who later considered himself the father of the suburbs.

It has more than 17,000 single-family houses, and until 2000 it had 53 thousand inhabitants.

Levittown was the salvation for many of the families that after World War II had to live in shelters, vans or chicken coops. And although it started as a commercial project, it ended up being the largest suburb and the first one that existed.
