The average American lives in a fairly considerable city, depending on your definition of "large." The vast majority live in cities of 100,000 or more.
Almost half of Americans live in the 100 largest MSAs. For perspective, the #100 MSA is Fort Wayne, Indiana, at roughly 500,000 people.
Not to mention, struggling to make rent, homelessness, and poverty don't just vanish when you step away from the most expensive cities.
