Animated US County View Of Unemployment
Watch this animated sequence of unemployment in the United States by county starting in September 2007. That is all.
THere's a few of these around ...http://tipstrategies.com/archive/geography-of-jobs/ is my personal favorite.
I've seen charts on regional quality of life issues like levels of poverty, quality of public education, and levels of crime, and they come up with a map that looks just about the same. The states that have been "stengthened" by diversity come up quite short in comparison to the non-diverse ones. You can use the stats over at Statemaster to check it out. The states are a bit outdated, but still pretty instructive.
At the end of the sequence states, in the middle eastern part of the US, from Michigan down to Alabama have a dark outline around them. This implies that unemployment is higher on both sides of state lines in those states than it is in the middle of the states. If I'm reading the maps correctly that would be a very unexpected result, at least to me.
Anybody have a possible explanation?
The state borders are black and the county borders are white. If the state borders were drawn as thicker white lines instead of black lines or using any other color that has high contrast to the colors in the legend, the effect would go away.
The effect I am seeing is due to the color of counties at state borders, not the boundary lines. Run the animation until it stops and then look at the following points:
* The boundary between Michigan and Indiana and Ohio. Counties on both sides of the border are more likely to be a darker color than the rest of Indiana
* The southern border between Kentucky and Tennessee, the counties on the Kentucky side are more likely to be darker
* The southern border of Tennessee, especially with Alabama is darker on the Tennessee side.
If you can see these borders then some of the other cases, such as the border between Indiana & Ohio will become more apparent.
I don't see it.
* Michigan itself is much darker than most states. It doesn't surprise me that the problems in Michigan spill over into nearby areas of Ohio and Indiana.
* The border between Kentucky and Tennessee has a mixture of black and purple on both sides of the border just as they have in the interior.
* The area around Huntsville including where it spills over into Tennessee is doing better than most places.
* The border between Indiana and Ohio is a mix of black and purple just like the interiors of those states.
