The Congressional Budget Office has released Changes in the Economic Resources of Low-Income Households with Children:

This CBO paper was prepared at the request of the Ranking Member of the Senate Budget Committee. It uses data from national surveys to examine the economic resources over a 15-year period for low-income households with children. Cross-sectional data are used to identify changes in the sources of income for that group over time. Longitudinal data are used to follow a group of households, classified as lowincome households in one year, to show how the economic resources of a given household might change over a three-year period. In keeping with CBO’s mandate to provide objective, impartial analysis, this paper makes no recommendations.
