This page pulls together UN World Population Prospects 2024 country data for the Indian diaspora, explains why the gap exists, and lets you go one step further — estimating your own life expectancy based on 8 evidence-based lifestyle factors rather than a national average.
Averages describe countries. This tool describes you.

Singapore's life expectancy of 83.7 years places it among the longest-lived nations globally. Its success is built on near-universal healthcare, one of the lowest infant mortality rates in the world, and a public health culture that keeps chronic disease in check. The famous hawker-centre food culture, while rich, sits alongside high walkability and active-ageing programmes that keep older Singaporeans mobile and socially engaged.
The UAE's life expectancy of 82.9 years has risen sharply over recent decades on the back of heavy investment in world-class hospitals and preventive screening. The lifestyle picture is mixed: a young, largely expatriate workforce and rising incomes coexist with challenges from desert heat, sedentary office life, and higher rates of diabetes. Government wellness drives and mandatory health insurance continue to push the figure upward.
India's life expectancy of 72.0 years is the reference point most of the diaspora grew up with. The 11.7-year gap between India and Singapore is driven far less by genetics than by healthcare access, air quality, sanitation, and lifestyle — which is precisely why relocating and adopting local health habits can meaningfully change an individual's outlook.
The UK, home to a large and long-established Indian community, sits at 81.3 years. It offers a useful midpoint between Singapore's figure and India's, showing that even among high-income destinations, life expectancy varies with diet, activity, climate and healthcare model.
The Indian Diaspora in Singapore and the UAE
The Indian community is a defining part of both countries. More than 350,000 Indians live in Singapore, where they form one of the major ethnic communities, and around 3.5 million Indians live in the UAE, making them the single largest expatriate group in the country. For these families, local life-expectancy figures are not foreign trivia — they describe the environment their own health is shaped by every day.
The encouraging news is that the 11.7-year gap between India (72.0) and Singapore (83.7) is overwhelmingly explained by healthcare access, sanitation, air quality and lifestyle — not by ancestry. Comparing against the UK (81.3), another major diaspora hub, tells the same story: environment and daily habits move the number far more than genetics do. That means the choices an individual makes about diet, movement and stress genuinely matter.
The 8 Factors That Shape Your Life Expectancy
National averages are a starting point. Your personal life expectancy is decided by the compounding effect of daily habits. Research shows these 8 modifiable factors account for 70–75% of longevity variance:
Smoking is the single most powerful modifiable risk factor. Smokers lose an average of 10 years of life expectancy compared to non-smokers.
The optimal longevity BMI range is 21-23. Each 5-unit increase above 25 reduces life expectancy by approximately 0.9 years.
Heart disease, diabetes, and hypertension each independently reduce life expectancy. Critically, whether the condition is managed changes the impact dramatically.
Diet quality affects longevity through inflammation, cellular repair, metabolic function, microbiome diversity, and epigenetic expression.
Sleep is when your body executes cellular repair, consolidates immunity, and regulates hormones. Both short and long sleep are associated with increased mortality.
Physical activity is the closest thing to a longevity drug. The dose-response curve is non-linear: the steepest benefits come from going from sedentary to lightly active.
Chronic high stress elevates cortisol and produces systemic inflammation, directly accelerating epigenetic ageing measurable through DNA methylation markers.
Social connection is the most consistently underestimated longevity factor. Strong social relationships increase survival odds by 50%.

What is the life expectancy in Singapore and the UAE?
According to the UN World Population Prospects 2024, estimate for 2023, life expectancy in Singapore is 83.7 years — among the highest in the world — while the UAE sits at 82.9 years. Both are well above India's figure of 72.0 years, largely due to differences in healthcare access, sanitation and lifestyle rather than genetics.
Why do Indians in Singapore and the UAE tend to live longer?
Members of the Indian diaspora often benefit from the healthcare systems, food safety, sanitation and air quality of their adopted countries. Singapore's universal healthcare and the UAE's heavy investment in hospitals and preventive screening both raise the baseline. The gap with India of about 11.7 years for Singapore is driven by environment and lifestyle, not heritage, which means individual habits still matter enormously.
How large is the Indian community in Singapore and the UAE?
There are more than 350,000 Indians in Singapore, forming one of its major ethnic communities, and around 3.5 million Indians in the UAE, where they make up the single largest expatriate group. These sizeable communities make local life-expectancy data directly relevant to millions of people of Indian origin living abroad.
How is my personal life expectancy different from the national average?
A national average like 83.7 for Singapore is a population statistic. Your personal life expectancy adjusts that baseline up or down based on your own smoking, BMI, chronic conditions, diet, sleep, exercise, stress and social connections. Research shows these lifestyle factors account for 70–75% of longevity variance, so two people in the same country can differ by 20 years or more.
How do I calculate my own life expectancy?
Use the BornClock longevity calculator, which starts from a population baseline for your country (UN WPP 2024 where available, otherwise a WHO regional average) and adjusts it across 8 evidence-based lifestyle factors. The quiz takes about 3 minutes and returns a personalised estimate, a longevity score and a 90-day action plan — free, with no account required.
