A documentary analytical study was made, using several descriptive measures, in order to identify explanatory components of the evolution of sex differential of life expectancy at birth in the Cuban population during the 20th century, making emphasis on the last 20 years. Arriaga´s method was used and adapted to the objectives of this study (sex differential) so as to analyze the contributions by ages and causes of death to life expectancy at birth. Three stages by which the Cuban sex differential has gone through are considered in this study: Steady deterioration (1900-1925), Progress (1925-1955) and Oscillation and Stabilization (1955-2000). The Cuban women have experienced a slower rate of increase of their life expectancy than that of the men, being females aged under 5 and 40-59 years more affected in the above-mentioned periods due to overmortality caused by conveyable diseases, congenital abnormalities, diabetes, asthma and musculoskeletal diseases. Mortality from conveyable diseases as compared to non-conveyable diseases has affected slightly more the Cuban women, so its reduction will raise their survival rate. Favorable evolution and change of sex differential of life expectancy at birth is a challenge for the Cuban society. The increase of such differential would directly depend on the improvement of the general population's quality of life and particularly of that of the women from early ages to the end of life
