Introduction to Special Issue: Constructing a Demography of Sexual Orientation and Gender Identity (Part 1)

This introductory article by Saori Kamano discusses the significance and necessity of demographic research on SOGI (Sexual Orientation and Gender Identity) in Japan. While traditional demography has assumed heterosexuality and cisgender identities, the visibility and inclusion of sexual minorities has become a social imperative, necessitating the construction of demography that incorporates SOGI perspectives. The author argues that introducing SOGI perspectives into major demographic themes such as fertility, mortality, migration, and household/family formation enables a more comprehensive and accurate understanding of population dynamics. Future research challenges include developing appropriate survey methods, promoting international comparative studies, and applying findings to policy.
