During which period did the suburban population in North America experience significant growth?

The suburban population in North America saw significant growth during the post-World War II period. This era was marked by various social and economic changes that contributed to the expansion of suburban areas. Following the war, there was a notable increase in the birth rate, often referred to as the "baby boom," as returning veterans settled down and started families. This demographic shift created a strong demand for housing.

Additionally, the economic prosperity of the post-war years provided many families with the financial means to purchase homes, often in suburban developments that offered more space and a different lifestyle than urban environments. The GI Bill also facilitated home ownership for many veterans, further driving suburban growth by providing low-interest loans for houses.

Furthermore, advancements in transportation, particularly the increased availability and affordability of automobiles, made commuting from suburban areas to urban job centers more feasible. This allowed families to enjoy the perceived benefits of suburban living, such as safer environments, larger homes, and access to green spaces.

This era fundamentally reshaped the American landscape, leading to the development of numerous suburban communities that continue to exist today, making it a crucial period of growth for suburban populations in North America.
