Intended to be a Protestant majority nation, six counties had been partitioned from Ireland, based on religious data from the 1911 census. Then, 34.4 percent of what would be Northern Ireland was Catholic and 61.4 percent was Protestant, a ratio of 1:2.

Just over 100 years later, the switch has finally happened, which according to The Guardian was anticipated due to Catholic birth rates being higher.
