This question is a bit like proving a negative, but I think I can provide some insight.

The first thing to consider is time. The United States was only engaged in the Great War for a few short months. The changes that occurred in those months was astoundingly rapid, but still, there wasn't a lot of time for population shifts and transformations during the war. WWII, on the other hand, lasted from 1941-1945, with a few years of occupation and reconstruction of Europe and Japan on top. This provided a big enough window for substantial demographic transformation of cities, particularly Northern cities, such as African-Americans moving from the South into the cities. White flight out of the cities to avoid living near black people was part of the rise of suburbia.

Second, automobiles were more numerous and effective after WWII. This allowed the middle class to move further away from urban centers to the outskirts. This trend began in some cities -Philadelphia springs to mind - in the 19th century, where mass transit systems like streetcars and trolleys enabled the creation of commuter communities. Cars and good roads for them expanded the commuter belt around city centers.

The GI Bill, however, was the biggest reason for the ride of suburbia. Servicemen could use the bill to obtain favorable rates on loans and a college education. With cheap credit and good-paying jobs, the WWII generation could afford houses more readily than previous generations of veterans, who never had such courtesies extended to them.

Starting in the late 1800s there were 'rail road' suburbs around quite a few large cities, NYC, Philly, Chicago etc. Typically these were very upper class, Victorian and Craftsman houses. After WW1 there were quite few suburbs growing up quickly, especially out west, the 'California Bungalow' was a more middle class housing style that was very popular. Probably biggest problems was building roads fast enough and probably there were problems with financial loans for middle class buyers, then the depression happened that stopped all growth. Then after WW2 the production capacity for cars and road building was huge. Even cheaper suburbs were built, places like Levittown.
