The ageing of the population structure is, at least partly, the result of an increasing life expectancy. This increase has meant that life expectancy for 80 year-olds rose from 8.4 years in 2005 to 9.2 years in 2015.

Although the proportion of women in the population aged 80 and over shrank between 2006 and 2016, they still accounted for around two-thirds (64%) of elderly people in the EU. All Member States have an over-representation of women among people aged 80 and over.

In the Czech Republic, there were 4% of population aged 80 and over in 2016, the fourth lowest share among the EU member states. At the same time, Czech population has the seventh lowest life expectancy at the age of 80 in the EU, according to Eurostat (at the age of 80, life expectacy is 7.2 years for males, and 8.5 years for females).
