This paper statistically analyses the relationship between subjective life expectancy and various demographic, social and economic factors. We compare SLE with census-based life expectancy. Results suggest that unisex samples between late 30s and late 60s in general underestimate their life expectancy relative to national data. But while younger women also underestimate life expectancy, younger men over-estimate time to death relative to national estimates. Econometric model analysis focuses on provincial levels covering age, sex, education, health, marital, income and social relationship and retirement arrangements. The results indicate that demographics and family relationships are more important than economic status in people's perceptions of their life expectancy.
