Marriage and mortality: a life table analysis

Area of Science:

• Demography
• Sociology
• Public Health

Background:

• Widowhood incidence varies significantly between sexes.
• Socio-cultural factors like age at marriage influence marital status duration.
• Differential mortality rates between males and females are a key demographic concern.

Purpose of the Study:

• To investigate the impact of age at marriage and sex-specific mortality on widowhood incidence in a rural Bangladeshi population.
• To quantify the relationship between life expectancy differences and widowhood rates.
• To identify key determinants of the disparity in widowhood between males and females.

Main Methods:

• Utilized abridged life tables derived from marital status and death registration data.
• Analyzed data from a rural area in Bangladesh spanning the period 1974-1979.
• Calculated life expectancies and probabilities of spousal survival.

Main Results:

• Female life expectancy is 0.4 to 2.2 years greater than male life expectancy.
• Despite similar survival probabilities, widows are approximately ten times more numerous than widowers.
• Age at marriage and spousal age difference are critical factors influencing widowhood rates.

Conclusions:

• Age at marriage and differential mortality are primary drivers of the high incidence of widowhood in the study population.
• The observed disparity in widowhood rates highlights the need for gender-sensitive demographic analysis.
• Policy implications may involve addressing age at marriage and understanding mortality differentials to support widowed populations.
