Catholics outnumber Protestants in Northern Ireland for the first time since the British province was created 101 years ago, according to 2021 census data available today.
According to these data, 45.7 percent of the population of Northern Ireland are Catholic or raised in a Catholic environment, 43.5 percent are Protestant, while 9.3 percent belong to neither of these two groups.
The historic reversal comes five months after Sinn Féin, the mainstay of the Catholic nationalist party, won regional elections for the first time in its history, giving impetus to its proposal to call a referendum on Irish reunification.
After the War of Independence (1919-1921), the United Kingdom divided the island into two jurisdictions, the province of Northern Ireland and the state of the Republic of Ireland, a solution that paved the way for nearly a century of tension and armed conflict between the two communities.
The peace agreement in 1998 officially ended the conflict, and since then the number of Protestants has been steadily decreasing, from 53 percent in 2001 to 45.7 percent in 2021.
In this latest census the question of national identity was also addressed, and 31.9 percent of the population declared that they consider themselves "British only", while 8 percent chose the option "British and Northern Irish".
