Early Childhood Poverty and Adult Attainment Greg J. Duncan University of California, Irvine The National Forum on Early Childhood Policy and Programs
Poverty rate for children < 6 years old
My talk: Does poverty compromise children’s life chances? How would adult outcomes change in response to a policy that boosted poor children’s family income, but did not directly change any other characteristic of their parents or family environments?
A Process Model Early childhood poverty Purchased inputs Cognitive stimulation in the home Type and quality of child care Quality of schools and neighborhood Family processes Maternal mental health Parenting Child Achievement, Behavior and Health Early brain development Adult Achievement, Behavior and Health
The Empirical Model Early childhood poverty Adult Achievement, Behavior and Health
Adult Outcomes (up to age 37) Completed schooling Labor market earnings and hours Welfare income receipt Health Arrest and incarceration Out of wedlock child bearing
Data and Sample Panel Study of Income Dynamics (PSID), Children born between 1968 and 1975 Adult outcomes measured between ages 25 and as late as age 37 for the earliest cohort Income measured prenatal to age 15; demographic controls measured around or before birth

Adult attainment and early-childhood income Early-childhood income
Regression model Adult outcome = f ( Prenatal to age 5 income + Age 6-10 income + Age income + Prenatal demographic controls )

Policy considerations Earnings coefficients imply: $3,000 increase in income for 7 years between prenatal and 5 th birthday year is associated with: 17% higher adult earnings 152 more work hours per year Concentrate income transfers (e.g., ETIC, child tax credit) on the p-5 periods?
