As of 2010, statistics released by the Office for National Statistics showed that life expectancy at birth for females was 89.8 years in 2008–2010, the highest in the United Kingdom. Male life expectancy at birth for the same period was 85.1 years. The figures in 1991–1993 were significantly lower: 73.0 years for males (ranking 301st in the nation) and 80.0 for females (ranking 129th). Further investigation indicates a 12-year gap in life expectancy between the affluent wards of Chelsea (Royal Hospital, Hans Town) and the most northerly wards of North Kensington (Golborne, Dalgarno), which have high levels of social housing and poverty.
