The number of Catholics living in Northern Ireland outnumber Protestants for the first time since it was created, census figures show.
The numbers for 2021 reveal that 45.7% of the population are Catholic, compared to 43.5% who are Protestant.
A decade ago the previous census showed Protestants outnumbered Catholics by 48% to 45% after falling below 50% for the first time.
The shift could drive support for the region to split away from Britain and join a united Ireland.
The 2021 figures also showed 9.3% of the population as belonging to no religion, up from 5.6% in 2011.
