The Welfare, Children and Families Study is a longitudinal study of children and their caregivers in low-income
families that were living in low-income neighborhoods in three cities in 1999. The purpose of the study is to
investigate the consequences of policy changes resulting from the Personal Responsibility and Work Opportunity
Reconciliation Act of 1996 (PRWORA) . The survey was designed to provide information on the health and
cognitive, behavioral, and emotional development of children and on their primary caregivers' labor force
behavior, welfare experiences, family lives, use of social service, health, and well-being.
The data come from completed interviews conducted between March and December, 1999 with 2,402 children and their
caregivers in Boston, Chicago, and San Antonio. The population of inference is children age birth to 4 and 10
to 14 who have a female primary caregiver, whose caregivers self-identify as non-Hispanic white, non-Hispanic
African-American, or Hispanic of any race, and who live in families with incomes below 200 percent of the
poverty line, living in low-income neighborhoods in Boston, Chicago, or San Antonio.

JHU has issued errata notices describing two minor discrepancies in
Wave 1 (CWP01-04) and Wave 2 (CWP 24-29) of the Three-Cities datasets.
Please download the errata notices here:
CWPDA #01-04 has been updated. Six variables have been removed from the earlier public use version of this dataset
at the request of the original investigators. The following variables, found in the original release of #01-04, have
been deleted from the latest release: MEX01549, MEX01550, WFS01551, WFS01552, WFS01553, and WFS01554.
Five new variables have been added to the new release of this dataset: IVX01549 "INCENTIVE FOR EXPERIMENT (SCREENING
VARIABLE)", MEX01552 "PRIMARY FRAME UNIT", MEX01550 "SEGMENT IDENTIFICATION NUMBER", RES01551 "CITY", and RAS01553
"RACE / ETHNICITY STRATUM".
Variables MEX01552, MEX01550, RES01551, and RAS01553 enable users to conduct an analysis accounting for clustering
effects. An explanation of how to use these four variables is included in appendix E of the user's guide. Value
labels for four variables, RSS02842, RSS02820, RSS02818, RSS02821, and RSS02819 are also corrected in this new file.
As a result of these changes, the current dataset includes 3538 variables, one less than the original public release.
Documentation providing descriptive statistics for all affected variables is included in appendix D of the user's
guide.
