GOP Outrage in 2016 Race
One big factor in that angst is wages. Stories of flat or negative wage growth have been a consistent part of economic news coverage in the past decade - or more - but wage stagnation is not a problem everywhere. Data shows it is closely tied to where people live and, indirectly, their politics - with big city, Democratic-leaning places generally doing better overall.
Increasingly, those places are hubs for industries like tech, finance, media and real estate
- think of New York, Los Angeles, Chicago and Denver, all of which have seen upticks in average pay over the period.
Politically speaking, they hold a lot of votes and tend to be strongly Democratic in their voting habits. Everyone one of those big cities, and many others, went for President Obama in 2012.
Conversely, in that top group of 238 counties, many of the Republican-voting entries are more sparsely populated places that saw a spike in wage growth with the oil and gas extraction boom.
On the list are counties such as Williams, Slope and Dunn counties in North Dakota, all of which have populations of less than 30,000.
