Where young people live in Ireland — Census 2022 age data

Where Ireland's young population lives has changed significantly since 2016. University towns, inner-city rental clusters, and fast-growing commuter towns all show distinct under-35 demographic profiles. Census 2022 maps these patterns at electoral division level — the most granular available picture.

What drives young population concentration

Under-18s — where children are most concentrated

Kildare, Meath, and Louth have the highest shares of under-18s nationally. These are the family formation counties — households with children, owner-occupied homes, and a median age in the mid-30s rather than the early 40s of the most rural counties. School infrastructure pressure is most acute in these counties as a result.

Young workers and employment

Census 2022 captures employment status by age band. The highest youth employment rates are in south Dublin, Wicklow, and Kildare — the professional employment belt. The highest youth unemployment rates are in the inner cities of Dublin, Cork, and Limerick — mirroring the broader deprivation patterns in those areas.

Third-level attainment among under-35s has risen sharply nationally. The gap between the most and least educated young cohorts — visible in the Pobal Deprivation Index at ED level — reflects both geography and socioeconomic inheritance.
