The Evolution of State Pension Ages and the Science Behind Gender Differences
The state pension age for both men and women in the UK is currently set at 66 years. However, this equality was not always the case. Historically, women were eligible to claim their pensions as early as 60, while men had to wait until 65. This disparity was gradually phased out over several years, with the pension age for women being increased in stages until it reached 66 by 2020. Since then, the retirement age has continued to rise, with plans to increase it to 68 for both genders by the 2040s.
This change has sparked significant debate, particularly among a group known as "Waspi" women, who argue that they were not given sufficient notice about the changes and are now campaigning for compensation. Their concerns raise an important question: should men and women be retiring at the same age at all?
Why Were Pension Ages Different?
The original difference in pension ages stemmed from assumptions about physical capabilities. It was once believed that women, as the "weaker sex," would struggle to work into their 60s. However, as societal roles evolved, so did the policies. In the 1990s, the government legislated for equal pension ages, citing two main reasons: the increasing role of women in the workforce and the need to adjust pension ages due to longer life expectancy.
Life expectancy has indeed risen significantly over the past century. Women, on average, live slightly longer than men—approximately 83 years compared to 79 for men. This longevity makes the earlier pension eligibility for women seem inconsistent. Baroness Ros Altmann, a former pensions minister, noted that men often felt the system was unfair, as they were effectively discriminated against.
The Science of Longevity
Why do women tend to live longer? One theory is that it's linked to biological differences. For example, it was once thought that men's higher rates of smoking and drinking contributed to shorter lifespans. However, recent research suggests that this may not be the primary factor. Studies on mammals show that females generally live longer, pointing to deeper genetic or biological causes.
In mammals, sex is determined by chromosomes. Females have two X chromosomes, while males have one X and one Y. The Y chromosome is smaller and contains fewer genes, many of which are related to sex determination. In contrast, the X chromosome is larger and carries thousands of genes involved in various bodily functions.
During early development, one of the X chromosomes in female embryos is randomly inactivated in each cell. This means that women have a greater genetic diversity in their cells, allowing them to potentially adapt better to environmental and health challenges. As Dr. Sharon Moalem explains, this diversity could contribute to women's longer life expectancy.
Health and Longevity
While women live longer on average, this does not necessarily mean they remain healthier for longer. According to the Office for National Statistics, both men and women in England can expect to maintain good health until around 62.5 years of age. Similarly, both sexes are likely to remain disability-free until approximately 75.5 years old.
Despite these similarities, women often face financial disadvantages later in life. Many have taken time out of the workforce to care for children or elderly relatives, which can impact their pension savings. Morgan Vine of Independent Age notes that these gaps in employment can lead to lower lifetime earnings and reduced pension benefits.
Financial Disparities and the Case for Flexibility
Although men and women may have similar health outcomes in old age, women are more likely to face financial insecurity. This raises questions about whether the current pension system adequately supports those who have had less stable careers. Some argue that women should have the option to access their pensions earlier if they are in poor health or unable to work.
However, Baroness Altmann believes that the rules should remain the same for both genders. She argues that any exceptions, such as allowing terminally ill individuals to retire early, should be based on specific circumstances rather than gender. “I can’t think of any justification in modern society that says women should get their pension before men,” she said.
