Wage stagnation is plaguing the modern U.S. economy. The purchasing power of the average American hasn’t budged in decades while wage gains are increasingly going to the highest earners, according to Pew Research. 

Harvard Business Review points to three main criteria for wage growth in the U.S. In order for workers to get a raise, their productivity needs to increase in such a way that more is produced per hour—most commonly aided by technological advancements or new capital. That uptick in productivity should equate to sustained shares for those workers. Third, gains must be evenly distributed among the workforce and not only among the highest-paid employees. Productivity and wages in today's economy are on the rise but labor’s share of wage increases is shrinking, keeping the median wage stagnant.

Several subsets of the population experience higher wage growth than the others. Within a state, certain developing areas can be ripe for investment, creating new jobs and boosting the economy while other areas may fall victim to outsourced labor and disinvestment that slows down the local flow of cash. 

Using data from the 2013 and 2017 versions of the American Community Survey provided by the U.S. Census Bureau, Stacker compiled a list of 50 counties—one for each state—that had the largest positive-percent change in median household income from 2013 to 2017. The total number of households per state and county is listed, as is the percentage of households making $100,000 or more. To account for any outliers, counties had to have at least 5,000 households to be considered for the list.
