Income and (less frequently) consumption are both used as indicators of changes in economic well-being. We consider the pros and cons of each of these measures of well-being, discussing both conceptual and measurement issues. Conceptual arguments as to whether income or consumption is a better measure of material well-being almost always favour consumption. Both measures are reported in surveys with error. However, empirical evidence indicates that consumption is more accurately reported, particularly for those at the bottom of the distribution. For example, measures of material hardship or adverse family outcomes are more severe for those with low consumption than for those with low income, indicating that consumption does a better job of capturing well-being for these families. Within survey comparisons of income and consumption for the same families indicate that income is significantly underreported at the bottom, and this evidence is supported by new research that relies on income data in surveys linked to administrative records. We show that income and consumption measures of economic well-being generate very different patterns for changes over time in inequality and poverty.
