With a life expectancy of just 40 years, a populaion will lose about 205,000 people per from various causes.

Deaths in Ireland in 1847 were 242,000. About 37,000 more than would be expected.

Official records show about 6000 died that year of starvation, which leaves about 31,000 who died from epidemic diseases. Typhus, cholera and relapsing fever are to blame for most of the daths, not the Brits.

Again, about 80% of the excess deaths do to epidemic diseases, 20% from the food shortage.

That is why I coined the term Irish Bad Years to replace the various ones blaming Brits or potato blight.
