Disability Free Life Expectancy: What do we know?

Disability-free life expectancy (DFLE) is an estimation of the length of time that an individual can expect to live free from a limiting long-standing illness or disability, and therefore adds a qualitative dimension to measures of life expectancy (LE). Previously only available from 2001 Census data, the Office of National Statistics (ONS) has made available estimates of DFLE at local authority level for males and females at ages 16 and 65, derived from data collected in the Annual Population Survey1. This data is based in the 3-year period 2006-8, includes 95% confidence intervals, and is accompanied by overall life expectancy at these ages (without confidence intervals). The following table shows overall life expectancy at age 65 and DFLE at the same age, for males and females for South East London boroughs, London, and England.

For both males and females Lewisham’s overall life expectancy at age 65 was the lowest in South East London in 2006-8. For females the DFLE was the lowest in South East London, though the difference was only statistically significantly different from Bromley. The following charts show the same data graphically.

The following table shows overall life expectancy at age 16 and DFLE at the same age, for males and females.

For females Lewisham’s overall life expectancy was the lowest in South East London. For neither males nor females was the DFLE significantly different from any of the comparators. The following charts show the same data graphically.
