There has been much press of late on income inequality, but many may not realize that the question of income inequality or the distribution of wealth has been a thorny topic for at least 200 years. The following are some recent publications that have a bearing on this problem: Changes in the Distribution of Income Among Tax Filers Between 1996 and 2006: The Role of Labor Income, Capital Income, and Tax Policy (a MUST read, CRS); Growth in the Residential Segregation of Families by Income, 1970-2009 (US 2010 Project); U.S. Neighborhood Income Inequality in the 2005-2009 Period (Census Bureau); Income Distribution (Brookings) ; and Is Income Inequality A Problem in the U.S.? (NPR). For statistics on this topic, please visit the Income, Expenditures, Poverty, and Wealth section of the 2012 Statistical Abstract of the United States. This question is not limited to the United States: Employment and Social Developments in Europe 2011 (Chapter 2 concentrates on income inequality, European Commission); Divided We Stand:Why Inequality Keeps Rising (a substantive examination, OECD); Income Inequality, various reports(World Bank); Inequality and Unsustainable Growth: Two Sides of the Same Coin? (IMF); and World Income Inequality (Conference Board of Canada). And what brought this discussion to the forefront is this CBO report: Trends in the Distribution of Household Income Between 1979 and 2007.
