The incredible rise of centenarians
The centenarian population in the UK has shown a consistent upward trend over the last two decades. In 2023, the estimated number of people aged 100 or over in the UK was 16,140, more than double the 7,980 recorded in 2003. While there was a slight decrease from the 2022 estimate, the long-term data indicates a growing population of those living to advanced ages.
Why are more people living to 100?
Several factors contribute to the rising number of centenarians in the UK, reflecting improvements in public health and living standards. Key reasons include advancements in medical treatments for diseases, improved public health initiatives like vaccination programs, and healthier lifestyles, such as reduced smoking rates. Better living standards, including nutrition and housing, have also played a role. Historical birth cohorts, like those born after World War I, have also influenced the numbers in specific years.
The gender and regional divide
Women continue to make up the majority of the centenarian population, with 13,180 female centenarians compared to 2,950 men in 2023. However, male longevity is increasing at a faster pace.
The proportion of centenarians varies across the UK's countries. In 2023, Wales had the highest rate per 100,000 people at 25.7, followed by England (24.3), Scotland (18.2), and Northern Ireland (15.1).
Living arrangements for the oldest old
According to 2021 data for England and Wales, 41.6% of centenarians lived alone in private households, while 39.1% resided in communal establishments, mostly care homes. For those living with others, 65.8% lived with a child or stepchild.

The challenges of an ageing population
The increase in people living to 100 and beyond presents challenges for healthcare and social care systems. These include higher demand on the NHS and long-term care services due to complex health needs, concerns about the sustainability of pension schemes, the risk of social isolation, and a need for more skilled caregivers.
The quality of later life
Experts emphasize the importance of prioritizing the quality of life in old age, not just lifespan. This involves focusing on preventative healthcare, promoting healthy lifestyles, and ensuring access to social support and suitable housing.

Conclusion
The UK's centenarian population has grown significantly due to improved healthcare, living conditions, and healthier lifestyles. While still a small part of the overall population, their increasing numbers impact social and healthcare systems. Addressing the needs of this demographic, covering health and social aspects, is a key policy challenge. The rise of centenarians is a notable achievement, but requires planning for a high quality of life for the oldest generation.
