The difference between life expectancy at birth can vary by over a decade between European Union member states. For example, in 2012 the life expectancy at birth for Swedish males is 81 years, whereas in Lithuania a baby born could expect to only live until 68.4.[4] In terms of healthy life years (years of life lived without disability) the gap is even greater, with Estonian males born in 2012 predicted to have 18.4 fewer healthy life years than their Maltese counterparts. These disparities in life expectancy don’t just exist at the macro scale, but can be seen right down to the neighbourhood level; with differences reaching into the decades.[5] Such disparities are found worldwide, with a whole area of research looking at demographics and improving life expectancy.[6]
