Sample Design
• Nationally representative sample of children born in 2001.– sampling frame drawn from U.S. birth certificates.
• Oversamples of special populations– low birth weight – American Indian/Native Alaskan– very low birth weight – Asian/Pacific Islander– twins – Chinese*
• n 14,000.
* The separate oversample of Chinese infants permits precision in statistical comparisons of Asian/Pacific Islander infants with members of their largest ethnic subgroup.
Study Design
• Data are collected at multiple points in time.
• Data are collected from multiple sources.– children – teachers– mothers and fathers – schools– child care providers
• Data are collected through multiple methods.
