The largest of Leinster's 256 recorded places, ranked by population — 2,561,027 people across the region's towns and cities.
The essentials
Dublin is the largest place we record in Leinster, with 1,024,027 residents. The three largest together hold 45% of the 2,561,027 people counted across the region's recorded towns and cities. That total sums listed places rather than measuring the region itself, so treat it as coverage, never as an official population.

Figures are the latest available in
GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are
UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such.
