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

Pupils in schools that teach all subjects through Irish (1 school today). 359 pupils in 2025/26, 8.9% of the area's pupils, against 1.5% in 2015/16. Each school counts under its current classification for every year.

Growing and falling since 2015/16

Each school's change in pupils over 10 years, from 2015/16 to 2025/26. A change of 10% or more either way counts as growing or falling.
