  Large parts of those states are not included in the diamond he outlined, but if you add them all up, all 5 states, it's about the same GDP as California. But, 53.5 Million people vs 39 million in CA.

    for the most part, outside of the major cities, the rest of the state is not generating much gdp

      But there are major cities in those states not included in his Diamond. Most notably: Philadelphia, Springfield, Peoria, Lansing, MI, Grand Rapids, Mich, etc

        Philly isn't in the Midwest, hell, it's almost in the Atlantic!

          That was his point. The article said that a region it outlines has an economy bigger than California. But adding up the GDP [1] of all the states that overlap that region gives an economy about the size of California's. Philly is in a state that overlaps the region, but is not in the region. Hence, adding up the state GDPs overestimates the GDP of the region by at least the GDP of Philly. [1] technically, I believe it is actually called the GSP (Gross State Product) in this case.
