Increased Survivorship of Females in Contrast to Males- a Global
Phenomenon!
Author: Vivian Abadi
Abstract
This study investigates the differences in survivorship between males and females in
California. Survivorship, which measures how long individuals live, is essential in understanding
demographic trends. The primary purpose of this research is to explore why females generally
live longer than males, examining biological, behavioral, and social factors that might contribute
to these differences. To achieve this, I gathered existing population data from the U.S. Census
Bureau and created a detailed dataset by converting a population pyramid into table data. I then
created survivorship curves for both males and females, illustrating their survival rates at
different age intervals. My central hypothesis was that females in California have higher
survivorship rates than males across various age groups. The results supported this hypothesis,
showing that females consistently have a higher proportion of survivors at each age interval
compared to males. For instance, at age 85, the proportion of surviving females was significantly
higher than that of males. In conclusion, the study highlights the persistent gender gap in
survivorship, suggesting that biological factors like stronger immune responses in females,

behavioral factors like healthier lifestyle choices, and social factors all play roles in this
disparity. These findings contribute to a broader understanding of gender differences in
longevity.
Introduction
Today I will be taking you all into a deep dive into a comparison of male and female
survivorship in the state of California. Survivorship refers to how long someone or something
lives or survives. It's about understanding how many individuals of a particular group survive
over time, especially in relation to factors like age or environment. I chose to examine males and
females specifically in California since Californians tend to have healthier lifestyles compared to
people living in other regions where obesity is quite common. Through the use of survivorship
curves and demographic data analysis, I aim to illustrate the survival trends across different age
groups for both genders. The null hypothesis in this study is that there is no difference between
the survivorship of males and females in the state of California. However, the central hypothesis
driving my investigation is that females have a higher life expectancy compared to males in
California. This study aims to uncover the increased life expectancy of females in contrast to
males, not just in California but around the world, exploring the difference in survivorship by
looking at biological, behavioral, and social factors as possible reasons.
