paragraph_text: The US federal government imposed the first personal income tax, on August 5, 1861, to help pay for its war effort in the American Civil War - (3% of all incomes over US $800) (equivalent to $21,800 in 2017). This tax was repealed and replaced by another income tax in 1862. It was only in 1894 that the first peacetime income tax was passed through the Wilson - Gorman tariff. The rate was 2% on income over $4000 (equivalent to $113,000 in 2017), which meant fewer than 10% of households would pay any. The purpose of the income tax was to make up for revenue that would be lost by tariff reductions. The US Supreme Court ruled the income tax unconstitutional, the 10th amendment forbidding any powers not expressed in the US Constitution, and there being no power to impose any other than a direct tax by apportionment.

paragraph_text: Conservative researchers have argued that income inequality is not significant because consumption, rather than income should be the measure of inequality, and inequality of consumption is less extreme than inequality of income in the US. Will Wilkinson of the libertarian Cato Institute states that "the weight of the evidence shows that the run-up in consumption inequality has been considerably less dramatic than the rise in income inequality," and consumption is more important than income. According to Johnson, Smeeding, and Tory, consumption inequality was actually lower in 2001 than it was in 1986. The debate is summarized in "The Hidden Prosperity of the Poor" by journalist Thomas B. Edsall. Other studies have not found consumption inequality less dramatic than household income inequality, and the CBO's study found consumption data not "adequately" capturing "consumption by high-income households" as it does their income, though it did agree that household consumption numbers show more equal distribution than household income.

paragraph_text: Another common measurement of personal income is the mean household income. Unlike the median household income, which divides all households in two halves, the mean income is the average income earned by American households.

As a result, the mean tends to be higher than the median income, with the top earning households boosting it. Overall, the mean household income in the United States, according to the US Census Bureau 2014 Annual Social and Economic Supplement, was $72,641.
