Swedish Twin Registry

Overview

The Swedish Twin Registry (STR) is an (inter)national resource, and data from the registry can become available to academic and industry-based researchers.

Founded in 1961, STR covers all same-sex twin births since 1886, and all twin births (same and opposite-sex) since 1926.

Regardless of research interest, all potential projects requiring data access must be reviewed and approved by STR's Expert Committee. 

Application

• Applicants with a PhD, MD, or equivalent degree may submit an application to the STR.

• Before applying, researchers can contact the STR for additional information or request a feasibility test.

• Ethical approval from the Swedish Ethical Review Authority is required for all applications.

• Non-Swedish applicants must collaborate with a Swedish university to ensure ethical compliance.

• Applications are reviewed on a first-come, first-served basis by the STR Expert Committee, which meets quarterly.
