Is Castlemartyr a good place to live?

Castlemartyr is a safe place by the numbers (A−): recorded crime comes to 3.7 violent offences and 2.7 burglaries and acts of damage per 1,000 residents a year. Work and incomes are strong (A−): 73% of working-age residents are employed, with an unemployment rate of 7%. The median home here went for €270,000, 4.6 times the median household income. Hazard risk is its weak spot (C) — an estimated 14% of homes are above the radon reference level. The rest of its grades are middling: B for health and B for walkability.

Figures: crime, CSO recorded crime, 2023 to 2025 · work, health and commuting, CSO Census 2022 · radon, EPA · prices, Property Price Register, 2023 to 2025 · incomes, CSO. With fewer than 2,500 residents, Castlemartyr gets subject grades but no overall one among Irish towns.

Rents for this town aren't published on their own, so its Cost Grade uses the county's average rent. Health less sure: few enough residents report bad health that the town's figure could be well above or below its true level.
