I'd like to do a follow-up on Steve Sailer's monetary standard-of-living by state post, but using a more valid cost-of-living measure than he did. The Missouri Economic Research and Information Center (MERIC) quarterly puts out a nationwide cost-of-living by state table. That's where Steve's CoL data come from.
MERIC gets its numbers from ACCRA's (now called C2ER) cost-of-living index, which measures CoL by city across six cost categories, which are then used to compute each city's total CoL index score. MERIC comes up with a simple average for each state using all of the cities within that state that participate in the survey. It makes no adjustment for population size. So in California, the cities of Palm Springs and Los Angeles are given equal weight in determining the CoL for the state as a whole.
Conveniently, this method makes Missouri appear more affordable relative to other states than it should. ACCRA uses 100 as its index average, so a city's score is always relative to the other city's participating during the same time period. MERIC boasts that Missouri has the fifth lowest cost-of-living in the country, at 90.3. If Missouri's composite score is adjusted for population size, it rises to 92.2. Only two of the seven participating cities are in the more expensive northwestern section of the state (Kansas City and St. Joseph), even though they represent nearly half of the participating population.
But for most states, the MERIC simple average actually makes them appear more costly than a weighted average would. The MERIC method yields a simple state average of 104.3 and a population-weighted state average of 106.3 for the US as a whole.
Since ACCRA's average is actually 100, the MERIC method is inflating most states' CoL, while deflating Missouri's. Again, Missouri's score of 90.3 using the MERIC method is lower than the 92.2 it receives when population is taken into account, something ACCRA presumably does. But the nationwide average is 104.3 or 106.3 using the MERIC method--higher than the ACCRA average of 100. Sneaky devils!
With access to ACCRA data for all participating cities across the country (MERIC's site shows the numbers for each of Missouri's particpating states), it would be possible to come up with a more accurate state CoL comparison than what MERIC provides. However, in Excel format, it runs at $95 for a single quarter.
Setting myself back like that is psychologically tough to do. I love blogging and wouldn't want (okay, wouldn't be able) to make a penny from it, but incurring accounting costs* in doing so is a hard pill to swallow, even a trivial amount like this. So if anyone happens to have access to the data and would be willing to send it to me, it'd be greatly appreciated. I wouldn't make the ACCRA data public, of course.
