Swedish Twin Registry

The Swedish Twin Registry (abbreviated STR) is a twin registry based at the Karolinska Institutet in Stockholm, Sweden. Originally established in the 1960s, it is the largest twin registry in the world. It is widely used for medical research, with about thirty active research projects using data from the study as of 2019.[1] As of 2012, it contained a total of 194,000 twins, 75,000 of whom were of a known zygosity.[2] In principle, it contains records of every twin born in Sweden since 1886.[3]
