County Mayo — what stands out
What stands out?
County Mayo has a notably high housing vacancy rate, ranking 4th nationally — 24.1% in Census 2022.
Why does it matter?
Housing vacancy is a barometer of housing demand and population pressure. A high rate signals supply vastly exceeding demand — whether from rural depopulation, seasonal use, or post-2008 ghost estates. A low rate signals the opposite: demand that supply cannot match, which directly drives rent and price inflation.

What's the likely explanation?
Mayo's high vacancy rate reflects decades of rural depopulation along the Atlantic seaboard — properties left empty as families moved east and overseas during the 20th century. The pattern is structural, not market-driven: demand is genuinely weak in many townlands, and the dispersed settlement of the county makes aggregated vacancy statistics look high even when individual villages are far from abandoned. Post-2020 remote working has drawn some reversal, particularly in coastal areas with strong broadband.
