(This is part of my explorations of PORDATA - A Portuguese open data database)
Here is the plot of total number of marriages per year.
- Number of marriages per year decreased from ~70.000 in 1960 to ~33.000 in 2019, even though population has increased.
- Number of marriages per year increased by 20.000 (!) from 1974 to 1975. This is probably somehow related with the fall of the Portuguese dictatorship in 1974 that lead to the immigration of more than 300.000 individuals to Portugal.
Here is the plot of number of same-sex marriages per year:
Only starts in 2010 because that’s when same-sex marriage was legalized in Portugal. There seems to be a weird pattern of things starting out slow but then ramping up. Don’t know why this might be, but I’ll ask around.
