The air pollution was a major reason to leave for the suburbs back then. Compared the the city, the fresh air likely added years of life expectancy to those living outside of it.
Cities have really only substantially reversed this in the past couple decades. Still a ways to go. Car pollution (NO2, particulate and noise) is probably the biggest problem now but cities are much cleaner and more livable than 1950
