My previous post presented the trends for the inequality topic on Google Trends, on the assumption that this referred to economic inequality, but as commentators pointed out this could have just been interest in other forms of inequality, such as mathematical inequalities.

In order to address this concern, here’s the data for searches for the exact words: ‘income inequality’ in the United States since 2004. I’ve included a 12 month moving average to remove seasonal variation and short term fluctuations. The data comes from here and the chart was produced in Minitab.
