Why do income and consumption measures of poverty tell different stories?
Core argument: Income-based poverty measured from Current Population Survey data with imputed taxes and credits fell sharply in 2021 and rose sharply in 2022, while consumption-based poverty from the Consumer Expenditure Survey declined steadily.
Poverty calculated using CPS income data with imputed taxes and tax credits indicate a large poverty decline in 2021 and a large increase in 2022, [while] consumption-based poverty calculated from the CEX show a steady decline in poverty. Spending data from the Fed’s SHED data also suggest consumption [of the poor] grew more than income in 2022. The puzzle is at least partially resolved by a pronounced increase in saving in 2021 followed by dissaving in 2022 by those with low income or consumption, and an increase in borrowing in 2022. This consumption smoothing behavior sharply contrasts with past evidence of hand to mouth consumption at the bottom of the income distribution and shows that the permanent income model has surprising applicability to the poor in certain circumstances.We estimate income poverty under counterfactual policy scenarios that exclude the enacted programs or the extension of discontinued programs. These indicate [that] while the expanded Child Tax Credit led to a significant decline in poverty, other policies including the stimulus payments and Pandemic unemployment benefits, played a similar or even larger role.
