Researchers considering levels and trends in the resources available to the middle class traditionally measure the pre-tax cash income of either tax units or households. In this paper, the authors demonstrate that this choice carries significant implications for assessing income trends. Focusing on tax units rather than households greatly reduces measured growth in middle class income. Furthermore, excluding the effect of taxes and the value of in-kind benefits further reduces observed improvements in the resources of the middle class. Finally, they show how these distinctions change the observed distribution of benefits from the tax exclusion of employer provided health insurance.
