DSDR is excited to announce the availability of the Age 2 data from Baby's First Years (BFY), New York City, New Orleans, Omaha, and Twin Cities, 2018-2021 (ICPSR 37871).

In addition to the data, this release includes English and Spanish questionnaires and a user guide from the Age 2 data collection. An errata document for the Age 1 user guide was also added and questionnaires for Age 1 were updated.

Approximately two years after each child’s birth, Age 2 data collected information about child health and development, maternal health, family income, and life. Phone interviews were conducted to collect information similar to the Age 1 data. 

The BFY project is a randomized controlled trial that estimates the causal impacts of unconditional cash gift payments on the cognitive, socio-emotional, and brain development of infants and toddlers in low-income U.S. families. Mothers of infants with incomes below the federal poverty line from four diverse U.S. communities (New York City, NY; New Orleans, LA; Omaha, NE; and Minneapolis/St. Paul, MN) were recruited after giving birth at one of 12 hospitals across the four study sites between May 2018 and June 2019. Quantitative data are collected at five points: baseline after child is born, at one year old, two years old, three years old, and four years old. 

Future waves of BFY data are planned for release through DSDR.
