Trends in Dolphin's Barn–D12
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. 433 in 2025/26, −4 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.
15 schools with figures for both years
Schools still filling their classes in 2015/16, and schools opened since, are listed separately.
Average class size in these schools went from 23.3 in 2015/16 to 19.5 in 2025/26. 4 of the 8 schools that fell by 10% or more kept or added classes. A fall in pupils can mean smaller classes rather than fewer children wanting places. Smaller classes

Grey margins of error are 15 points or more: so few parents answered that the figures could be well off. “Too few to publish”: the Department held back the school's results, but its parents' answers still count in the area figures. Not yet at school: how many parents of children not yet at school chose the school, shown where 30 or more did. Special schools in the area are counted in the area figures above.
Source: Department of Education and Youth, Primary School Survey results, published 23 June 2026. The area figures count each household once, including parents at schools too small for their own results, so they aren't the school figures added up. About these figures
Schools
17 schools, largest first. A dash in the change column means the school had no pupils recorded in that year, usually because it opened later or took a new roll number after an amalgamation.
