【Abstract】The disability level of the elderly population has an important influence on the estimation of healthy life expectancy. There are great differences in the disability level of the elderly population from different data sources. This paper is based on the life table calculated from the 1% population sample data adjusted by the model life table, based on data sources of 2010 census, the 1% sample survey in 2015, 2015 CHARLS and 2014 CLHLS. We study the influence of age-specific disability rate on healthy life expectancy and the reason of different disability situations. The results show that the disability rate of the elderly significantly affects healthy life expectancy and gender and age patterns. No matter whether it is the subjective or objective evaluation index of disability, the disability rates of elderly people from different data sources are quite different. The reasons for the bias of disability rate in CHARLS data may be caused by systematic errors in the course of investigation. The questionnaire interview design in the non-sample scale of CLHLS and CHARLS may also be an important factor to determine the degree of disability. Therefore, on the theoretical and practical level, it is an important problem to be solved urgently to explore the difference of disability level and its causes of the elderly population, especially for the oldest old, and to reach a consensus further.
