Manufacturing in the Great Cities as a Share of the National Economy

 

Notes:

The next tier of industrial centers, Ohio’s Youngstown, Dayton, Akron and Toledo, and Minneapolis/St Paul, Indianapolis, Washington DC and Newark, produced another 5% of U.S. value-added, from 2.7% of population.

Much infrastructure was pioneered in Great Cities: bridges, rail lines, electricity, water and sewerage systems, health and education service delivery systems, consumer goods, skyscrapers.

These centers boomed, then declined, and now innovate new forms of communal living, because they use infrastructure efficiently.
