Ireland
69 facilities across 33 cities. Divisions are shaded by the number of facilities recorded in each.
Bubbles are placed at the city centroid, not at a facility address: the catalogue releases location at city granularity. Bubbles with a solid edge are sized from reported capacity; those with a dashed edge from a figure derived off the facility’s own reported dimensions. A derived figure sizes a bubble and nothing else — it enters no total, ranking, or statistic anywhere on this site. Planned capacity is not operating capacity. The map plots 8,944 facilities across 3,987 cities; a campus is plotted once, at the campus. Division shading covers the 2 of 69 facilities whose recorded region matches a division name. An unshaded division means the catalogue records no matching region for its facilities, not that it holds none — every facility is still plotted by city.
