Notes on our processing step for this indicator
We converted the original data with the years of the legalization of same-sex marriage into a expanded dataset with the legal status of same-sex marriage for each country and year.
We estimated regional aggregations of these status by using Our World in Data definitions of regions and our consolidated population data.
