Insurance Risk & Actuarial Analysis
Explore how mortality data translates into insurance risk classes, premium multipliers, and actuarial survival curves. Compare countries, age groups, and risk factors through the lens of life insurance underwriting.
This page is for educational and informational purposes only. It does not constitute insurance advice, actuarial analysis, or underwriting. Risk classes shown are simplified estimates based on population-level mortality data and do not reflect individual medical history, family history, lifestyle details, or any insurer's actual underwriting criteria.

Not insurance advice. The risk classes, premium multipliers, and actuarial calculations on this page are simplified educational estimates based on publicly available population-level mortality data from the IHME Global Burden of Disease study. They do not represent any insurer's actual underwriting process.
Individual risk varies greatly. Actual insurance underwriting considers medical records, family history, lab results, prescription history, driving records, occupation, hobbies, and many other factors not captured here.

Understanding Actuarial Mortality Data
How death rates inform life insurance pricing and pension planning
Life insurance and pension systems are built on mortality tables — statistical models that estimate the probability of dying at each age. This page bridges the gap between population health data (from the IHME Global Burden of Disease Study) and the actuarial frameworks used by insurers. It translates age-standardised death rates into formats familiar to actuaries: risk classes, mortality multipliers, and survival probabilities. The tool is designed for educational purposes and should not be used for commercial underwriting.
Actuarial science depends on understanding how mortality varies by age, sex, country, and risk factors. A 40-year-old non-smoking male in Japan faces fundamentally different mortality odds than a 40-year-old smoking male in Russia. This page quantifies those differences using population-level data and presents them through the lens of insurance risk classification: preferred, standard, substandard, and high-risk categories based on where a country’s mortality falls relative to global benchmarks.
Risk Classes and Mortality Multipliers
How insurers translate population mortality into individual risk pricing
Life insurers assign applicants to risk classes that reflect their expected mortality relative to a standard table. “Preferred” risks (non-smokers in excellent health from low-mortality countries) may pay 50–70% of standard rates. “Substandard” risks (those with health conditions, smokers, or residents of high-mortality countries) may face multipliers of 150–300% or higher. This page maps country-level mortality data onto a simplified version of this risk classification system, showing where each country falls on the global mortality spectrum.
The rectangularisation of survival curves (visible on the Age page) has profound implications for insurers. As more people survive to old age, life insurance becomes cheaper for younger applicants but annuity costs increase. The shift from infectious to chronic disease deaths also changes actuarial assumptions: chronic diseases are more predictable than infectious disease epidemics, which allows for more stable pricing models but also means that emerging risks (pandemics, antimicrobial resistance) can disrupt long-standing actuarial assumptions.
How to Interpret the Insurance Charts
Understanding mortality tables, survival curves, and risk stratification
The Mortality Rate by Age chart shows how death probability increases with age for a given country and sex — the fundamental building block of any life table. The Survival Curve converts these age-specific rates into a cohort survival probability, showing what percentage of a hypothetical birth cohort would survive to each age. The Risk Class Distribution maps countries onto a global spectrum of mortality risk, helping visualise where different nations sit relative to each other. Together, these tools provide an accessible introduction to the actuarial data that underpins trillions of dollars in insurance and pension liabilities worldwide.
What is a mortality table and how is it used in insurance?
A mortality table (or life table) lists the probability of dying at each age, typically for a specific population (e.g. US males). Insurers use these tables to calculate expected claim payouts, set premiums, and determine reserves. The tables on this page use population-level data from the GBD study, which differs from the insured-lives tables used commercially (insured populations tend to be healthier due to selection effects).
How do insurance risk classes work?
Life insurers classify applicants into risk tiers based on health, lifestyle, and demographic factors. Common classes include Preferred Plus (lowest risk), Preferred, Standard, and Substandard (rated). Smokers are typically placed in separate, higher-cost tiers. This page maps country-level population mortality onto a simplified version of these classes, showing where each country falls on the global risk spectrum.
Why does country of residence affect life insurance premiums?
Country of residence reflects the healthcare system quality, disease environment, safety infrastructure, and lifestyle patterns that collectively determine mortality risk. A person living in Japan (low mortality) faces fundamentally different risks than someone in Sierra Leone (high mortality). International insurers and reinsurers use country-level mortality data when pricing policies for expatriates or multinational group coverage.
What is rectangularisation and why do insurers care?
Rectangularisation is the trend toward more people surviving into old age, with deaths concentrated in a narrower age window. For life insurers, this means lower claim rates for younger policyholders (good for pricing). For annuity providers and pension funds, it means longer payout periods (increasing costs). The survival curves on this page illustrate this trend by comparing different countries and time periods.
How did COVID-19 affect actuarial assumptions?
COVID-19 caused a significant spike in mortality in 2020–2021, leading to excess claims for life insurers and temporarily disrupting long-term mortality improvement trends. Actuaries are still debating whether to treat COVID as a one-time event or a structural shift. Most are currently treating it as an outlier while monitoring for long-term effects (such as Long COVID impacts on future mortality). The pandemic highlighted the importance of pandemic risk modelling in actuarial science.
Can I use this tool for actual insurance pricing?
No. This tool uses population-level mortality data for educational and exploratory purposes only. Commercial insurance pricing requires insured-lives mortality tables, individual underwriting assessments, regulatory compliance, and qualified actuarial oversight. The data here provides context for understanding how mortality varies globally, but should never be used for pricing, reserving, or underwriting decisions.
