The census is only published once every 10 years but there are other publications each year which give us an insight to changes in demographics on a yearly basis. The Schools Census/School Enrolment Statistical Bulletins which give an annual breakdown of the religious composition of 5 to 18 year olds. The Labour Force Survey gives us an annual demographic breakdown of the working age and general population aged over 16 years old. The Equality Commission Monitoring Report also provides a breakdown of the composition of the North's workforce year on year.
The Schools Census for the year 2017/2018 shows that Catholics are have a majority of 51% of the school population while Protestant minority has declined to 37%. Those of No Religion/Religion Not Stated account for 12%.
The latest Labour Force Survey Religion Report showing the 2016 figures has shown a large adjustment on the prior year figures in the Population Aged 16-24. Compared with 2015 the Catholic percentage plummeted by 9 percentage points from 51% to 42% while the Protestant percentage increased from 36% to 38%. This adjustment goes against overall trends all other sources of demographic data.
Parity had been reached among the two communities among the Population Aged 16 and Over in 2015. The trends showed that in 2016 that Catholics would outnumber Protestants in this age group for the first time. Because of the adjustment among the 16 to 24 year olds the percentage of Catholics fell from 44% to 42%. Others increased from 12% to 14%. Protestants remained unchanged at 44%.
The Population Aged 60+ has not changed. The percentage split remains 57/35/8.
There is a very strong correlation between voting preference and demographics in the North. The trends are clear. There is a Catholic plurality in the North and there will soon be more people voting for Nationalists than Unionists. We have entered the final stage of the Endgame In Ulster.
