An analysis of UN data (for all countries where data for 2013 or newer was available) shows that the oldest grooms in the world can be found in Italy, where men get married at the median age of 35.

The oldest brides live in Ireland (median age of 32.4 years), which is also the country with the smallest age gap between men and women. Grooms were on average one year older than brides in Ireland, reflecting a global trend of male median marriage ages always being higher those of females.
