Hypothesis
The study aims to specify the level of mortality selection among nonagenarians and centenarians in five low mortality countries.
Conclusion

- Denmark and Sweden experienced stronger mortality selection compared to Japan.
- France and Switzerland had an intermediary level of mortality selection.

This study looked at how many very old people live in different countries and how healthy they are. It found that some countries have more healthy centenarians than others.
Methodology
Data was collected from the Human Mortality Database and analyzed for mortality experiences of birth cohorts.
Limitations
The study does not provide direct information on the health status of centenarians currently reaching their 95th or 100th year.
Participant Demographics
