  Abstract: Objective To investigate the gender differences and time-space distribution characteristics of healthy life expectancy of the elderly population aged 60 and above in China from 2010 to 2020, and to provide an empirical basis for promoting gender equality and regional balance in healthy life expectancy. Methods Based on the data of the sixth and seventh censuses, the healthy life expectancy of the elderly population aged 60 years and over in China was calculated by Sullivan method, and the period change and gender difference were compared, and the spatial distribution characteristics of the proportion of healthy life expectancy remaining were analyzed by spatial autocorrelation (Morans I) and LISA tests. Results Health rates decrease with age, and the health rate of the male elderly population is higher than that of women in most age groups, with differences mainly concentrated in the older age group and narrowing over time. Both average and healthy life expectancy have improved, with gender differences manifested in women being higher than men, and female older adults increasing and growing faster than men. The proportion of healthy life expectancy remaining on the basis of expanding over time is that men are higher than women, but the sex difference is narrowing, and the spatial distribution of the proportion of healthy life expectancy remaining is characterized by the fact that the health level in the east is better than that in the west, and the concentration between regions has deepened in the past decade. Conclusion The health level of the elderly population in China has improved in recent ten years. Women have advantages in longevity, but there is still a gap in quality of life compared with men; The proportion of the elderlys remaining healthy life expectancy is expanding, which is in line with the disease compression theory. At the same time, the gender imbalance is closing, while the phenomenon of agglomeration between regions has increased.
