Each year counts the schools in this planning area today, plus any that closed from 2023/24. Dotted lines bridge 1983/84 to 1992/93. 1974/75 is left out because that year's source file is missing five counties.

Earlier years are incomplete

The Department's files only record planning areas from 2023/24, so schools that closed or amalgamated before then aren't counted in any area. The further back you go, the more pupils are missing, and an amalgamation can look like a sudden rise. Across County Dublin, schools with no planning area had 1.5% of pupils in 2015/16, 5.3% in 2005/06 and 36.8% in 1975/76. Known data issues
