The EU has a stance on life expectancy

A better piece of research than Marmot, who should be lumped together with montbiot and marmite.
It would be interesting to see if the decrease on a country by country basis correlates with the size of the sub saharan immigrant communities, where life expectancy at birth is at least 10 years less.
To counter this holocaust survivors had an increased life expectancy.
Could it be argued that survivors and migrants are better survivalists due to genetics and outlook, or simply happenstance?
It is obviously a far more complex subject and requires a far more intricate analysis than marmot's cheap political shots.
