People in the North of England live two years less than those in the South of England and boys born in the most deprived neighbourhoods of England can expect to live nine years less than those born in the most affluent wards (ONS, 2015). For baby girls, the gap is seven years. In our case study town of Stockton-on-Tees in the North East of England, the gaps in life expectancy are even greater – some of the largest in the world – as there is a 15-year gap in life expectancy between men living in the most affluent suburbs such as Hartburn and those living in the most deprived such as Town Centre ward (PHE, 2017). For women the gap is 11 years. Perhaps most shocking of all is that these two neighbourhoods are only two miles apart.
