The future
3. Mortality in the next Millennium
4. Mortality in the next MillenniumThe fundamental idea In order to predict the future you need to understand the forces that have driven trends in past
5. Mortality in the next MillenniumAnother idea Trends are best understood by looking at patterns in population experience
6. Five key forces The “cohort effect”
The “ageing” of mortality improvement
Increased uncertainty at younger ages
Changes in the prevalence of cigarette smoking
Widening socio-economic class differentials

12. Acceleration of scientific advances Scientific breakthroughs are occurring at a faster and faster pace
Human knowledge is doubling every 10 years
Computer power is doubling every 18 months
The Human Genome Project produced a first draft in 2000
13. Uncertainty at younger agespopulation of England & Wales - males
14. Changes in the prevalence of cigarette smoking
15. Widening socio-economic class differentials The differential between the mortality of different socio-economic classes has been growing since the Second World War
CMI investigations have also shown more rapid improvements than the general population
16. An alternative basis for future mortality projection An alternative “cohort” projection was constructed in which:
trends were projected by year of birth not attained age (to allow for the impact of the cohort effect)
improvement rates reduce from current levels to “long-term” averages as the smoking effect unwinds
The new CMI basis (CMIR17) is equivalent to:
1.1% p.a. improvements for a 65-year-old male
The “cohort” basis is equivalent to:
2.4% p.a. improvements for a 65-year-old male
17. Mortality in the next MillenniumKey Conclusions Life expectancy at retirement is likely to increase at a faster rate than ever before
The new CMI basis (CMIR17) significantly understates the likely improvements
Profound implications for:-
the annuity market
life offices with GAO’s
pension funding
18. Critical Illness Trends
19. Previous views on future trends Society of Actuaries in Ireland Working Party (1994):
for reserving recommended 1% to 3% p.a. increase in incidence
Werth & Mannion (1998):
2.8% p.a. increase in incidence?
Critical Illness Healthcare Study Group (2000):
current reserving practice for guaranteed CI products is 1% to 2% p.a. increase in incidence
20. Critical Illness - major areas of “concern” Earlier diagnosis of cancer
Low-grade cancers (e.g. prostate)
Increasing cancer incidence
Increasing use of CABG & angioplasty
Improved detection of micro-strokes & mini-heart attacks
Genetic testing
Weak definitions
Anti-selection
21. Cancer

23. Trends in cancer mortality - females
24. Trends in cancer incidence - males
25. Trends in cancer mortality - males
26. Improvements in cancer survival
27. Lung cancer incidence - males
28. Cancer (other than lung) incidence - males
29. Cancer (other than lung) incidence - females
30. Cancer (other than lung) incidence - females
31. Mortality from cancers related to smoking - males
32. Mortality from cancers related to smoking - males
33. Cancer - summary Incidence of smoking-related cancer is highly dependant on year of birth, especially for men
Incidence of other cancers has changed less over time, but there is evidence of increases for men
New screening programmes & earlier detection can have a significant impact over a short period of time
Survival rates are improving for virtually all cancers
It is highly likely that mortality rates from cancer will reduce in coming decades
34. Heart disease
35. Recent improvements in heart disease mortalityEngland & Wales population - people aged 65-69
36. Heart disease mortality - males
37. Heart disease mortality - males
38. Heart disease - an international perspective
39. Heart disease - an international perspective
40. Heart disease mortality - summary Heart disease mortality is highly dependant on year of birth
Between 1985 & 1995 heart disease mortality improved by
4.3% p.a. for men
4.0% p.a. for women
In the late 1990s improvements have been even more rapid
Most experts predict that the improvements in coming decades will be very significant
41. Heart-related critical illness claims Many critical illness policies include:-
heart attack
CABG surgery
multi-vessel angioplasty
Heart attack incidence has been reducing significantly in recent years (e.g. 3.6% p.a. for men aged 45-64 between 1981-82 & 1991-92)
This is consistent with the improvements in mortality plus evidence (e.g. MONICA Project) that approx 2/3 of mortality reduction is due to fewer heart attacks
42. Operations involving CABG or MVA
43. Heart disease - risk factors & treatments
44. Factors influencing future CI claims
45. The Future
46. The Future - critical illness In the long-term the underlying incidence of “critical illnesses” will actually reduce
Heart disease incidence is already reducing steadily
Cancer incidence will reduce as a result of behaviour modification stemming from greater understanding
However critical illness claims are likely to increase because of earlier detection
The effects are difficult to quantify, but the example of breast cancer screening is useful
47. The Future - mortality Accelerating improvements at older ages will be amplified by generational effects
By 2030 the main causes of death may well be pneumonia, dementia & “old-age”
Using a range of different techniques - such as cause of death modelling - is a good way to assess the reasonableness of future projections
48. The Future There will be a massive increase in information relating to:-
the incidence of illness
mortality & demographics
Intensification of price competition will reduce profit margins
Changes in distribution may reduce market imperfections and increase the risk of anti-selection
Hence the need to maximise the potential of the new information
