April 2012
In 2010, more than 1 in 5 children lived in
poverty and 15.1 percent of all persons were poor.Government spending on anti-poverty
programs includes $30 b. on TANF, $51 b. on the EITC, and $50 b. on Food Stamps.In this talk, I discuss what we know about the
causes of poverty and its consequences for children and families. 2Outline

A family is poor if their family income is less than the federal poverty threshold Poverty lines vary by family size and are adjusted for changes in prices each yearBased on the cost of food in the 1960s (multby 3)
family have the same poverty statusPoverty Thresholds by Family Type,
20101 parent, 1 child$15,030
1 parent, 2 children$17,568
2 parents, 2 children$22,113
5By comparison, 2010
median family income was $49,400.Concerns about official poverty measure
Income measure is pre-tax family income; includes only cash income Does not include Food Stamps (SNAP) or Earned Income TaxCredit
Not adjusted for work-related expenses
Not adjusted for regional variation in costs of living (e.g., housing) Definition of poverty has not changed since measure developed in early 1960sRecent Supplemental Poverty Measure released by
Census; addresses these concerns

How do we define poverty?
Facts: Poverty in the U.S.
Impacts of poverty on children and families
The causes of poverty and how government
policies can help 16Poverty is measured and watched by virtually
all developed countries.It is an important indicator of economic well-
beingIn the U.S., poverty is associated with many
adverse outcomes 17Children who grow up poor are more likely to
Not attend preschool
Perform worse in school
Drop out of high school, have lower educational attainment (Girls) Have a teen birth (Boys) Be incarceratedLive in poverty as adults
Receive government assistance as adults
Have connection to the child welfare system
Have worse health and shorter life expectancy
18The challenge for social science research is in
identifying:1.The role played by poverty in these correlations.
2.What policies can improve outcomes.

These figures show that economic growth
does not necessarily translate into reductions in poverty 35Government policies that reduce poverty
or don't (and why) 36The U.S. Social Safety Net for Families
TANF: cash welfare
Food Stamps (now SNAP): vouchers for food
Earned Income Tax Credit: tax-subsidy for low earnersMedicaid: health insurance
Subsidized housing
WIC, free or reduced price lunch
Unemployment insurance (not limited to low income families)Recent changes in the U.S. Safety Net
The U.S. safety net for low income families has
dramatically changed: More assistance through the federal taxes (the EarnedIncome Tax Credit)
More assistance through in-kind support (Food
stamps, Medicaid/SCHIP)Less assistance through traditional cash welfare
Much of my research focuses on estimating the
effects of the safety net on low income families. Cash and Near Cash Safety Net Spending per Capita, 2009$ 0 50100

How the EITC reduces poverty
1.Key design feature of EITC (and what
distinguishes it from traditional income support programs) is that eligibility requires earned income.The EITC transfers income to low income
families with children WHILE encouraging work.2.The generosity of the EITC increased
substantially with tax reforms in 1986,1990, and 1993.
