Strengths

 A curated teaching dataset is available for use in undergraduate or graduate studies. 

Includes a wide range of data collected over time covering a large variety of topics. Data includes:

  • Prenatal and postnatal interviews
  • Fetal and neonatal assessments
  • Physical measures
  • Self-administered questionnaires
  • Biospecimens
  • Environmental samples 
  • Master operational, special analysis, demographic, and biospecimen and environmental lab results datasets
Limitations

Due to funding issues the NCS study was cut short resulting in a smaller sample than originally planned for, some individual studies have small sample sizes.
