Answer:
3. Urban workers began to move to the suburbs
Explanation:
Suburb is a proper term of the urban geography, originating from the Latin suburbium, to design the residential areas of the urban or suburban periphery; The characteristics of the suburban or suburban zones, in the sense that it is given in the American urbanism, are determined for the social component of its population: young working-class people, who settle down in dispersed small multinuclei close to the city and communicated with good road systems towards the peripheries. The model of coexistence of social life is by friendships in public spaces, schools, squares, parties, etc., which gives uniformity to services and institutions and a quality of life of habitability superior to the city: green spaces, open landscape, etc., but transferring the same problems if planning is not taken care of and the factors that have caused the cities to decline are avoided, sometimes due to issues of social justice in relation to educational, health and leisure institutions, among others.
These citizens seek personal freedom as autonomy, greater spaces between family units, especially in North America, which converts neighborhood roads into streets oriented to regional highways and to a greater or lesser degree is the model in Europe. These conurbations reach their identity as cities of a new type: dispersed homes that have commercial, educational, health and technological centers that serve each of the portions or nuclei of the new metropolitan area, magnifying in the same sense the classic function from the main city with the classic role of an administrative center and services with fewer permanent inhabitants who have been displaced to the suburbs of cheaper housing or to nuclei of expansion at a reasonable distance from the workplace.
