National Siblings Day: April 10, 2023

Press Release Number CB23-SFS.47

From the Census Working Paper: Family Complexity and Child Well-Being, October 2019, SEHSD-WP2019-34, Brian Knop: “Family complexity is associated with child well-being, even when controlling for race/origin and poverty. Complex sibling arrangements are not uncommon in families today. However, children living with fewer siblings, only biological siblings, or with two parents had higher extracurricular involvement and more positive school experiences. Controlling for race and poverty narrowed this gap, but did not erase this relationship.”


  • FAMILY COMPLEXITY MEASURES: Number of siblings, Type of siblings (Biological, Step, Half, Adopted), and Parents in the home (Two parents, Mother only, Father only, Guardian).
  • CHILD WELL-BEING MEASURES: Extracurricular Activities (Plays a sport, Takes Lessons, In a Club) and School Experiences (In a gifted class, Ever expelled from school, Ever held back a grade).
