Setting a research agenda on sexuality and migration in demographic studies: what emerges from the literature review
DOI:
https://doi.org/10.20947/S0102-3098a0222Keywords:
Literature review, Global South, Internal migration, Sexuality, DemographyAbstract
This article systematically reviews articles published from January 2000 to June 2021, that focus on internal migration and sexuality using quantitative methods and data related to demographic research. Therefore, this article aims to map what has been studied and learned so far in demographic research regarding internal migration of sexual minorities. A second objective is to use the development of studies on sexuality and migration in Brazil as a case study for migration and sexuality in the Global South; from this retrospection I intend to identify where these studies have become stifled in the last decades as well as the gaps to fill in order to establish a research agenda.
