1. It’s mostly female
The country has distinctly more women than men. For every 100 females in Estonia, there are 84 men – only the Northern Mariana Islands, a US territory in the Pacific, with a population of around 50,000, has a smaller percentage of males. Estonian women live 10 years longer, on average, which goes some way to explaining it. Incidentally, the UAE is the country with the highest male-to-female ratio, a remarkable 2.19:1.
