Same‑sex marriages rose in Brazil after Bolsonaro’s 2018 win, study shows

Research using civil‑registry records reveals that Brazil saw a distinct, albeit short‑lived, increase in same‑sex marriages after the 2018 presidential election that installed Jair Bolsonaro as president.

By examining marriage data from periods preceding and following Bolsonaro’s swearing‑in, the team detected a brief uptick in unions between same‑sex partners. This boost was especially evident in municipalities with higher electoral participation, implying that the political atmosphere may have spurred a response among LGBTQ+ inhabitants.

Bolsonaro has often directed public remarks at LGBTQ+ groups, and his government has faced criticism for eroding safeguards for sexual minorities. Although the research stops short of asserting a direct cause, the timing of the surge closely matches a phase of intensified public discussion about the president’s position on gay rights.

“The data indicate that social and political events can influence personal decisions about marriage,” said one of the study’s co‑authors, who asked to remain unnamed. “When a political figure makes anti‑LGBTQ+ rhetoric prominent, some couples may choose to formalize their relationship as a form of visibility and resistance.”

Brazil has traditionally stood at the forefront of Latin America in acknowledging same‑sex unions, having legalized them across the nation in 2013. Nevertheless, the nation remains sharply split, with many conservative areas frequently contesting LGBTQ+ rights. Consequently, the post‑2018 election rise in marriages mirrors both the existing legal structure and the intricate social currents surrounding a polarizing leader.

Analysts warn that the increase was fleeting; within a year, same‑sex marriage rates fell back to pre‑election figures. This trajectory indicates that the bump was a reactive episode rather than a lasting transformation in public sentiment.

These results contribute to an expanding literature on how political discourse can shape personal conduct. With Brazil nearing its next election, researchers look forward to additional investigations to determine if upcoming political shifts will generate comparable impacts on LGBTQ+ populations and whether the short‑lived marriage rise will leave enduring marks on advocacy and policy.
