The objective of this study is to investigate social class differences in disability (in terms of physical function and mobility), survival and disability-free life expectancy at older ages in England. Data from a general population sample of residents aged 50 or older living in private households in England (n=11,392) were combined with life tables estimated from the total population of England and Wales aged 50 or older in order to estimate survival and disability. A disability index was constructed using questions on mobility, Activities of Daily Living and Instrumental Activities of Daily Living; life table functions were constructed by age, sex and social class, to give probability of surviving and life expectancy, by social class and gender; and disability-free life expectancy was estimated by integrating disability indices into survival functions. Social class is a strong predictor of both disability and survival; higher social classes having a lower prevalence of disability and higher survival chances. These findings apply to both males and females and all age groups in the 50+ age bracket. Disability-free life expectancy is longer among higher social classes for both males and females, showing that social class inequalities in life expectancy in England and Wales are amplified when disability-free life expectancy is also considered.
