In 1800, the population of the Isle of Ireland itself was 5.2 million and the rest of the UK was 10.8 million rising to just under 38 million in 1900 and 56 million in 1980.
What if there was no Irish famine, Irish emigration to North America was at UK levels and Irish population growth was also at UK levels?
Could the population of Ireland increase to around 30 million by 1980?
Could the landmass of Ireland support this population?
Cheers filers.
