New pregnancy and early childhood data file

The Pregnancy and Early Childhood (PEACH) data file is a single cross-wave file that brings together the key data reported by parents for all children aged under 10 years, plus information on pregnancy and parenting styles, from all waves of the main survey.

Understanding Society collects information across a wide range of topics before and after childbirth, coupled with data on the entire family, that provides contextual insights into child development. Children are themselves Understanding Society participants from birth, with parents providing information on their child’s health and development until the age of 10. When they turn 10 years old, children complete their own survey.

The new Pregnancy and Early Childhood (PEACH) file has been created to facilitate the easy tracking of various aspects of child development. PEACH is designed to be linked to the main Understanding Society datasets (EUL, Special Licence and Secure Access), so that the child’s development can be related to their broader family circumstances.
