Ireland’s land classified as settlements and other artificial areas expanded by 30,300 hectares between 2018 and 2024, according to ecosystem accounts published by the CSO on 7 October 2026. That was a 10.1% increase in the category’s area, bringing its share of the country’s land from 4.3% to 4.7%. [1]

Those two percentages answer different questions. The 10.1% figure describes growth relative to the category’s earlier size; the 4.7% figure describes its later share of all land. It does not mean that an additional tenth of Ireland was developed during the period.

Follow the land categories

The CSO identifies an expansion of 25,900 hectares in discontinuous settlement areas, including residential, commercial and industrial areas beyond built-up urban areas. Grassland and cropland ecosystems decreased by 36,600 hectares, or 0.8%, largely through conversion into settlements and other artificial areas. [1]

The accounts also record a 7,400-hectare increase in broadleaved deciduous forest and a slight 400-hectare decline in inland wetlands. These are changes in mapped extent. An area total alone does not establish habitat condition, the diversity of species at a site or whether a particular development was well planned. [1]

Use local information without overclaiming

The release includes county and local-authority breakdowns and maps for 2018, 2021 and 2024. Its background notes explain that the maps combine European and national geospatial sources. This is an account of changes across defined years, rather than a live record of construction taking place this morning. [1][2]

For a community group, a useful starting question is which land category changed locally and what period the comparison covers. A planning decision, an on-site ecological assessment and an ecosystem area account each provide different evidence. One should not be used as a substitute for the others.

Read the definitions before interpreting a map, and keep the reference year beside any figure you share. The new accounts make a broad pattern visible: settlement-related land has increased. Understanding what that means for a specific place requires the local breakdown and further evidence about the site itself.
