Trends in Tallaght
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.
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 these schools
Junior infants, girls and boys, and Irish-medium schools over time, for the same schools as the trends above.
Junior infants
Pupils starting school each year. Class-by-class figures start in 2020/21. 554 in 2025/26, −41 on 2024/25.
Girls and boys
From 1976/77: earlier files don't split every school's pupils into girls and boys.
Irish-medium schools
No school in this area teaches all subjects through Irish.
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.
17 schools with figures for both years
Schools still filling their classes in 2015/16, and schools opened since, are listed separately.

Ranked by percentage change. Only schools with 50 or more pupils in 2015/16 are ranked, leaving out any still filling their classes then, because a few pupils make a big percentage in a small or new school. An amalgamation or a new school nearby can also explain a big rise or fall.
Newer schools
1 school still filling its classes in 2015/16 or opened since, with 342 pupils. It isn’t in the figures above.
