Trends in Blanchardstown–West–D15

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

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.

Schools

7 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.
