This paper analyzes the population characteristics and average life expectancy of residents in Guangxi in the early 1990s. Results: The birth rate was 14.56 ‰ in Guangxi in the early 1990s, with a mortality rate of 6.01 ‰ and a natural population growth rate of 8.55 ‰. The average life expectancy of residents is 70.67 years, 67.92 years for men and 72.84 years for women. The main causes of death that have a significant impact on residents’ life expectancy are: respiratory diseases, cerebrovascular diseases, malignant tumors and accidental deaths. Respectively, after removing these causes of death, residents expect their life expectancy to increase by 4.21 years, 2.77 years, 2.12 and 2.01 years old.
