Health will start failing at the age of 47 in some parts of England and Wales, according to the latest figures from the Office for National Statistics.
From 2009 to 2013, males born in Bloomfield in Blackpool had a healthy life expectancy (HLE) of only 47.1 years, five months shorter than females born in Middlehaven in Middlesbrough.
People are expected to live healthily for three decades more in other areas.
However, the average gap between HLE in different areas was around 13 years.
The small area analysis showed the inequality in expected healthy lifespan across England and Wales.
Males born in Bloomfield could expect 32 fewer years of healthy life than their counterparts born in Knightsbridge and Belgravia in Westminster (79.1 years).
The gap between Middlehaven females and the highest figure was even starker – 35.4 years fewer than those born in Blackheath and Wonersh of Waverley in Surrey (83 years).
The longest overall life expectancy for people born in the period of the study was for females born in Great Corby and Geltsdale in Carlisle, who could look forward to 97.2 years of life.
