More women died at older age than men
Figure 7 shows the age-sex structure of registered deaths in 2023. It shows an inverted pyramid, with fewer deaths at younger ages, except for children under 1, and progressively increasing as people grow old. In the province of Sorsogon, there were 6,204 registered deaths of which 3,553 deaths or 57.3% of the total deaths are male while the remaining 2,651 deaths or 42.7% were females.
The proportion of males who died was largest at the age groups 65 to 69 years old with 11.1% share. While for females, the largest was at the oldest age group, 85 years old and over (708 or 12.6% of female deaths). (Figure 7 and Table 3)
The sex ratio of 134 indicates that there were about 134 male deaths for every 100 female deaths. Moreover, a sex ratio of over a hundred means that more male deaths were registered compared to the female counterparts at each group before 80 years old except for age group 1 to 4 years old.
