Why Do Women Have a Survival Advantage during a Disaster?

It’s common knowledge that women often live longer than men. And a new study from Denmark and Germany further underscores that fact. Even in the harshest living conditions, including severe famines and uncontrolled epidemics, women still have a survival advantage over men. Researchers from the University of Southern Denmark looked at the death rates during seven catastrophic historical events that occurred between 1772 and 1939. They found that during these times of particular hardship, women outlived men by an average of six months to four years.

When the going gets tough:

  • The study looked at data from events such as the Ireland's Great Famine (1845–1849), measles epidemics in Iceland (1846 and 1882), and slavery in Trinidad at the beginning of the 19th century.
  • During the Great Famine, for example, life expectancy for women dropped to an average of 22.4 years, while for men it plummeted even lower, to 18.7 years. Before the famine struck, the life expectancy for both sexes was about 38 years.
  • Most of the survival advantage that females had during a crisis was linked to infant mortality. The study showed that baby girls survived harsh conditions better than baby boys.

Frequently Asked Questions

What biological factors contribute to women's survival advantage during disasters?

Biologically, women generally have a higher body fat percentage, which can provide greater energy reserves in times of scarcity. Additionally, women's immune systems are somewhat stronger, which can be crucial in fighting off infections that may be prevalent during disasters. According to a study published in the Proceedings of the National Academy of Sciences, estrogen can play a role in immunological responses, potentially offering women an advantage in surviving infectious diseases.

How do social and behavioral factors affect women's disaster survival rates?

Social and behavioral factors significantly influence women's survival rates in disasters. Women often have strong social networks and community ties, which can be vital for sharing resources and information during crises. Furthermore, women's roles as caregivers can lead to the development of skills and knowledge related to health, nutrition, and resource management, which are essential in disaster scenarios. These social bonds and skills can be critical for survival, as noted in research on disaster resilience.

Are there any statistics that show women's survival advantage in disasters?

Yes, there are statistics that illustrate this phenomenon. For instance, a study analyzing the 2004 Indian Ocean tsunami found that in some areas, the survival rate for women was much higher than for men. According to the research, this was attributed to women's better swimming skills and stronger social networks, which helped them receive early warnings and assistance. Additionally, historical data often show higher mortality rates for men in famines and epidemics, suggesting a gender-based survival advantage for women.

Does women's survival advantage hold true for all types of disasters?

Women's survival advantage is not universal across all types of disasters. In certain contexts, especially where social norms restrict women's mobility or access to information, their survival rates can be lower. For example, during the 1991 cyclone in Bangladesh, cultural practices that limited women's mobility contributed to higher female mortality rates. Thus, while biological factors may offer some advantages, cultural and social factors can significantly impact survival outcomes.

How can disaster preparedness and response be improved to support women's survival advantage?

To support and enhance women's survival advantage in disasters, preparedness and response efforts should be gender-sensitive and inclusive. This means involving women in disaster planning and decision-making processes, ensuring they have access to resources and information, and addressing specific health and safety needs. Training programs that empower women with skills in first aid, emergency response, and resource management can also be beneficial. By leveraging women's inherent strengths and addressing societal barriers, communities can improve overall resilience to disasters.
