Approximately 2,500 people live year-round on Ireland's small offshore islands.

• No more recent data than the 2022 Census of Population (published 2023) exists for Ireland's island population; there is no 2025 or 2026 census, so the 2022 figures remain the most current available before the session date.
• The exact figure of 2,500 does not appear in the sources retrieved by these searches; the sources confirm Ireland's overall population and the existence of the official census framework, not the specific island sub-population.
• The count of 'offshore islands' depends on definition — whether islands connected to the mainland by bridge/causeway are included materially changes the total, which explains the spread of commonly cited figures between roughly 2,500 and 3,000.
