County Dublin — what stands out
What stands out?
County Dublin has the highest private renting rate in Ireland — 19.4% in Census 2022.
Why does it matter?
Dublin's dominance shapes every national average — property prices, employment rates, education, and income are all elevated by the capital's weight. Comparing any Irish county to the national average is implicitly comparing it to a benchmark that Dublin has pulled upwards. Understanding any Irish metric requires knowing where Dublin sits.

What's the likely explanation?
Dublin's very high renting rate reflects the concentration of young professionals, migrants, and students in the capital. With property prices far above national averages, owner-occupation is out of reach for a large share of the working population — even dual-income households. The city's economic dominance draws workers from every county, sustaining demand that keeps vacancy near zero and rents at a persistent premium.
