Which county is most rural in Ireland?

Leitrim has the smallest total population of any county in Ireland (35,087 in Census 2022) and one of the lowest population densities. Roscommon, Longford, and Cavan are similarly rural. County Mayo is the largest rural county by area, with most of its population spread across small towns and townlands rather than a single large urban centre.

Did rural Ireland grow in Census 2022?

Yes — Census 2022 showed population growth in many rural counties that had been declining, including Leitrim, Roscommon, and parts of Mayo and Donegal. Remote working is the primary driver: for the first time, workers no longer need to be in a city or large town to maintain professional employment. This reversed a decades-long trend of rural depopulation in the west and northwest.

Rural Ireland's Census 2022 comeback — population, remote work and recovery

Census 2022 caught rural Ireland mid-change. It was the first post-pandemic count, the first to measure remote working at scale, and the first to show population recovery in counties that had been shrinking for decades. IrelandInsights maps every electoral division, including the most rural.

What Census 2022 shows about rural demographics

Population recovery in the west: Counties like Leitrim, Roscommon, and parts of Mayo had lost population for years. Census 2022 recorded growth in some of these areas for the first time since the 1970s. Remote working is the main driver.
Home ownership dominance: Rural Ireland has the highest home ownership rates in the country. Leitrim, Roscommon, and Mayo have 75–80% owner-occupied households — far above Dublin or Cork city. This reflects both cultural preference and the lack of a private rental market at scale.
Education gap narrowing: Third-level attainment in rural counties has risen sharply since 2016. The gap to Dublin and Wicklow remains, but counties like Galway, Clare, and Kilkenny now approach national averages. Return migration and remote worker in-flows are driving this.
Older age profile: Rural Ireland has a higher median age than urban Ireland. Census 2022 age pyramids show the challenge of retaining young people — particularly 18–34-year-olds — in the most rural EDs in Leitrim, Mayo, and Donegal.
Household size declining: Average household size in rural areas has fallen toward the national average. Older inhabitants age in place, and the historic pattern of large families continues to change.

Remote work and rural repopulation

The 2022 census was the first to capture home-based working as a major trend. The EDs with the highest remote working rates fall into two areas: south Dublin — where highly-paid professionals work from home — and the rural west, especially Leitrim, Roscommon, and west Galway.

This marks a structural shift. Towns like Carrick-on-Shannon, Boyle, and Strokestown have seen higher residential demand. Census 2022 occupancy and household formation figures reflect this change.

Agriculture and rural employment

Agriculture remains a major employer in the most rural EDs. In Roscommon, Leitrim, Mayo, and Donegal, EDs with high agricultural employment also have the highest home ownership rates and the lowest median ages in children. Family farm succession acts as a social stabiliser in these areas.

Manufacturing and food processing are the other big rural employers, concentrated in county towns. IDA-anchored pharma and medtech clusters in Sligo, Athlone, Clonmel, and Carlow provide well-paying jobs that support the surrounding rural catchment.
