VALIDITY AND COVERAGE:

The linkage to biological and adoptive parents is close to complete, even biological fathers are registered for 91.4% of the adoptees.

CONCLUSION:

Adoption registers are a unique source allowing disentangling of genetic and familial environmental influences on traits, risk of diseases, and mortality.
