I love this map of population change from 1840 to 2021. The world has six times more people now than it did in 1840. And most countries have a lot more people. Ireland is an exception - it actually had more people in 1840.

Yes, it's a long and very sad story, and it's not finished!
Glad that #IrelandIsNotFull #mastodaoine
@Annela @conradhackett very interesting how closely Irish population tracked England until the #GreatHunger catastrophe
@mnutty @conradhackett
True! The world map in the previous post is very telling.
@conradhackett @Annela missed that one, thanks for drawing my attention to it. Surprisingly that other country has a similar profile.
@mnutty @conradhackett Yep, it's almost as if something dreadful happened... oh yeah, it did!

@Annela @conradhackett The #GreatHunger was the trigger for the most dramatic migration case in modern history. When combined with colonial misrule and culture, migration became the accepted norm.

Other counties had horrendous famines, indeed Ireland had a more devastating famine in 1740 - 41 (some estimates indicate 20% of population died), without the same long term population collapse
