States Where the Middle Class Is Dying

Income from capital gains may partly explain why the income distribution has skewed towards the rich in recent years. “We have seen the stock market recover quite well for many Americans who do have access to the market and who are investors,” Valenti said. Meanwhile, average workers do not.

According to data collected by Piketty, the average capital gain income of households in the bottom 90% was $558 in 2012. The average capital gains of the top 10% of households was nearly $30,000. And the comparable figure for the top 1% of U.S. households was a whopping $242,000 in 2012.

Several other factors, such as union membership rates and a particular state’s tax climate, such as no income tax or higher sales taxes, can also affect the redistribution of wealth across the nation. “Traditionally, union organizing has stepped in when policy makers have been unwilling to,” Valenti said. For example, depending on the union’s size and its sway, “policy makers may not feel the same pressure to pass or increase a minimum wage” if unions can negotiate a wage increase on their own.

While union organizing was a major component of the middle class’ formation in America after World War II, the level of labor force participation in unions fell from 12.4% in 2009 to 11.3% in 2013. In some states the decline was even more pronounced. Oregon’s union membership, for example, fell by 3.3%, the second largest decrease nationwide.

To determine the states where the middle class is suffering the most, 24/7 Wall St. used data on the average pre-tax income earned by each income quintile from the U.S. Census Bureau. We defined middle class as the third quintile, or the middle 20% of earners. We examined the growth in average incomes in the third and fifth quintiles between 2009 and 2013 to identify income trends in the middle and upper class. The final list was composed of states where middle class incomes fell by more than 4.3% and fifth quintile incomes rose by more than 0.4%, the national aver. Both benchmark figures reflect the national change of their respective quintiles. Because Census income data reflect pre-tax levels, they may overstate the degree of income inequality in the poorer quintiles. However, it is unlikely that the tax burden of the third quintile is significant enough to skew the data.

We also looked at data on the share of aggregate income by quintile from the Census Bureau, and how that share changed between 2009 and 2013. Also from the Census Bureau, we reviewed poverty rates, the share of households making less than $10,000 a year, as well as the share of households making more than $200,000 a year. All data are from 2009 to 2013. Additionally, we considered the Gini coefficient. The Gini coefficient indicates the degree to which an area’s incomes deviate from a perfectly equal income distribution. Scaled between 0 and 1, a coefficient of 0 represents perfectly equal incomes among all people. From the Bureau of Labor Statistics, we looked at annual unemployment rates from 2009 and 2013. The percentage of non-agricultural employees who identify as members of a union came from Unionstats.org. Tax data come from the Tax Foundation’s 2014 State Business Tax Climate Index.

These are the states where the middle class is dying.
