Economic growth is spreading to smaller cities. A recent report categorizes 100 cities into four groups. The largest cities account for a significant portion of national income and savings, despite having a relatively small population. Household earnings and spending vary across these cities.

Further details are available from the report, including information on household income and debt. The report provides insight into the economic trends of different city groups.

The economic dominance of certain cities is notable, with some cities leading in income and savings, while others have higher consumption rates.
