GDP growth rates by state in the USA take nominal state GDP growth rates and subtract CPI (or some other national average)... but the cost of living varies widely around the country, as do the changes in cost of living (aka "inflation"). Most everyone knows this, except perhaps @Casual_Observer
Since CPI understates inflation in high cost areas like Califorinia, the "real" (after inflation) growth rates for CA are overstated (real GDP growth is lower than reported). In the same way, inflation in lower cost areas is below CPI, which means the real growth rates in low cost areas are understated.
Pretty sure Mish, like milllions of others, figured this out since he is moving from high cost Chicago to lower cost Utah. I left high cost New York City a few years back, and moved to a much lower cost locale.
@Casual_Observer saw the mess that is California and moved in to CA, so its not a surprise that he is a little slow
