According to data released by the Office for National Statistics (ONS) life expectancy has risen.

In 2010, average life expectancy at birth across the UK, for both men and women, rose by another four months.

Further to that average life expectancy at age 65, for both men and women, rose by two months.

"The gap between the local areas with the highest and lowest life expectancies increased between 2004-06 and 2008-10," the ONS said.

"Life expectancy was highest in Kensington and Chelsea and lowest in Glasgow City in each period between 2004-06 and 2008-10."

Key points

- Life expectancy was highest in Kensington and Chelsea and lowest in Glasgow City in each period between 2004—06 and 2008—10

- On average life expectancy at birth in local areas improved by 1.2 years for males and 1.0 year for females

- At age 65 the average increase in local areas was 1.0 year for men and 0.9 years for women

-The gap between the local areas with the highest and lowest life expectancies increased between 2004—06 and 2008—10

- At birth the gap increased from 12.5 to 13.5 years for males and from 10.1 to 11.8 years for females

"The apparent advantage in the London region is likely to be due to a combination of factors, including the relative affluence of many parts of London, the movement into London of healthy, employed individuals at low risk of death, and the statistical effects of migration and high population mobility," the ONS explained.
