The battle over the assumed success of European socialism
continues. Many European countries like Sweden have gained a reputation as being
very wealthy in spite of their highly regulated and taxed economies. From
there, many assume that the rest of Europe is more of less similar, even if
slightly poorer. But if we look more closely at the data, a very different
picture emerges, and we find that the median household in the US is better off
(income-wise) than the median household in all but three European countries.
Worse than
Mississippi?
Last year, a debate erupted over how Britain would
compare to individual US states. In the UK
Spectator, Fraser Nelson explained "Why Britain is poorer than any US
state, other than Mississippi." A week later, TIME shot back with an article titled "No, Britain Is Not
Poorer than Alabama." The author of the TIME article, Dan Stewart, explained that, yes, Britain is poorer
than many US states, but certainly
not all of them. (See below to
confirm that the UK is, in fact, poorer than every state.)
The main fault of the Spectator
article, its critics alleged, was that it relied primarily on GDP and GDP per capita
to make the comparisons. The critics at TIME
(and other publications) correctly pointed out that if one is going to draw
broad conclusions about poverty among various countries, GDP numbers are
arguably not the best metric. For one, GDP per capita can be skewed upward by a
small number of ultra-rich persons. After all, it is just GDP divided by the
total population. That gives us no idea of how the median household is doing is
those areas. Also, it's best to avoid averages and stick with median values if
we're looking to avoid numbers that can be pulled up by some wealthy outliers.
This same criticism was applied to a 2007 study by
Swedish economists Fredrik Bergström and Robert Gidehag (and an article by Mark
J Perry) who had asserted that according to their calculations, Sweden was
poorer than most US states.
The Bergstrom and Gidehag study was no
back-of-the-envelope analysis, but given that they did rely largely on GDP per
capita data, I thought it might be helpful to use data that relies on median
income data instead, so as to better account for inequalities in income and to
get a better picture of what the median resident's purchasing power. Click for

The nationwide median income for the US is in red. To the
left of the red column are other OECD countries, and to the right of the red
bar are individual US states. These national-level comparisons take into account taxes, and include social
benefits (e.g., "welfare" and state-subsidized health care) as income.
Purchasing power is adjusted to take differences in the cost of living in
different countries into account.
Since Sweden is held up as a sort of promised land by
American socialists, let's compare it first. We find that, if it were to join
the US as a state, Sweden would be poorer than all but 12 states, with a median
income of $27,167.
Median residents in states like Colorado ($35,830),
Massachusetts ($37,626), Virginia ($39,291), Washington ($36,343), and Utah
($36,036) have considerably higher
incomes than Sweden.
With the exception of Luxembourg ($38,502), Norway
($35,528), and Switzerland ($35,083), all countries shown would fail to rank as
high-income states were they to become part of the United States. In fact, most
would fare worse than Mississippi, the poorest state.
For example, Mississippi has a higher median income
($23,017) than 18 countries measured here. The Czech Republic, Estonia, Greece,
Hungary, Ireland, Italy, Japan, Korea, Poland, Portugal, Slovenia, Spain, and
the United Kingdom all have median income levels below $23,000 and are thus
below every single US state. Not
surprisingly, the poorest OECD members (Chile, Mexico, and Turkey) have median
incomes far below Mississippi.
Germany, Europe's economic powerhouse, has a median
income ($25,528) level below all but 9 US states. Finland ranks with Germany in
this regard ($25,730), and France's median income ($24,233) is lower than both
Germany and Finland. Denmark fares better and has a median income ($27,304)
below all but 13 US states.
On the other hand, were Australia ($29,875), Austria
($28,735), and Canada (28,288) to join the US, they would be regarded as
"middle-income states" with incomes similar to the US median of
$30,616.
We Should Adjust
for Purchasing-Power Differences Among States
But, I'm really being too conservative with the US
numbers here. I'm comparing OECD countries to US states based on a single
nation-wide purchasing power number for the US. We've already accounted for
cost of living at the national level (using PPP data), but the US is so much
larger than all other countries compared
here, we really need to consider the regional cost of living in the United
States. Were we to calculate real
incomes based on the cost of living in each state, we'd find that real purchasing power is even higher in
many of the lower-income states than we see above.
Using the BEA's regional
price parity index, we can take now account for the different cost of
living in different states, and the new graph looks like this:
We now see that there's less variation in the median
income levels among the US states. That makes sense because many states with
low median incomes also have a very low cost of living. At the same time, many
states with high median incomes have a very high cost of living.
Now that we've accounted for the low cost of living in
Mississippi, we find that Mississippi ($26,517) is no longer the state with the
lowest median income in real terms. New York ($26,152) is now the state with
the lowest median income due to its very high cost of living.
This has had the effect of giving us a more realistic
view of the purchasing power of the median household in US states. It is also
more helpful in comparing individual states to OECD members, many of which have
much higher costs of living than places like the American south and
midwest. Now that we recognize how
inexpensive it is to live in places like Tennessee, Florida, and Kentucky, we
find that residents in those states now have higher median incomes that Sweden
(a place that's 30% more expensive than the US) and most other OECD countries
measured.
Once purchasing power among the US states is taken into
account, we find that Sweden's median income ($27,167) is higher than only six
states: Arkansas ($26,804), Louisiana ($25,643), Mississippi ($26,517), New
Mexico ($26,762), New York ($26,152) and North Carolina ($26,819).
We find something similar when we look at Germany, but in
Germany's case, every single US state
shows a higher median income than Germany. Germany's median income is $25,528.
Things look even worse for the United Kingdom which has a median income of
$21,033, compared to $26,517 in Mississippi.
Meanwhile, Colorado ($35,059) has a median income nearly
identical to Switzerland ($35,083), and ten states (Connecticut, Iowa,
Maryland, Minnesota, New Hampshire, North Dakota, South Dakota, Utah, Virginia,
and Washington State) show higher median incomes than Switzerland. Luxembourg
($38,502), on the other hand, shows a median income higher than every state
except New Hampshire ($39,034).
None of this analysis should really surprise us.
According to the OECD's own numbers (which take into account taxes and social
benefits, the US has higher median disposable income than all but three OECD
countries. Sweden ranks below the US in this regard, as does Finland and
Denmark.
The fact that the median level in the US is above most
OECD countries thus makes it no surprise that most of these countries then rank
below most US states. The US states that have income level above the median US
level will, not surprisingly, outpace many OECD countries by a considerable
margin.
Methods and Data
I began with the OECD's "median disposable
income" metric. This is a metric developed by the OECD to compare among
all member states. The measure takes into account taxes and social benefits
provided.
Then, we must adjust the numbers for purchasing power parity using the World
Bank's index. At that point, we can see how the US compared to other members
using dollars across all countries. I provided an analysis at the national
level here.
But, in order to compare to individual US states, we have
to come up with a way to make US states comparable. The OECD does not measure
individual US states, so I had to use the Census Bureau's measure of median
income for a place to start (2012-2013 2-year average medians). The Census
numbers are much higher than the OECD numbers for a variety of reasons. In
fact, the OECD income number of the US is only 59 percent of the Census number.
So, to roughly adjust state income levels for OECD
methods, I cut down state level income levels to 59 percent of their Census
total. This brought the median income level in Illinois, for example, down from
approximately $54,000 (Census value) to $32,000 (to estimate OECD value).
Similarly, one could also adjust for OECD methods by taking the OECD median
income for the US ($30,616) and then adjusting to fit each individual state's
median income in relationship to the
nationwide median. For example, Since Wyoming (according to the Census) has a
median income that is 109% of the national median income, we simply set
Wyoming's median income at ~ $33,600 which is 109% of the OECD median income
value of $30,616.
When adjusting for cost of living in US states, I then
adjusted each state using the regional price parity numbers provided by the
Bureau of Economic Affairs.Naturally, median income numbers for individual
states are already in US dollars.
Is median income a good metric for poverty comparisons?
Maybe, but in any case it's what OECD and UNICEF use. Typically, the
"poverty rate" is calculated as either 50% or 60% of the national
median income. So, apparently, the UN and OECD do think it's a relevant figure,
and if poverty rates are going to be invoked as reasons for new public policy,
then median incomes must be analyzed.
