Five key facts about Ireland’s counties, one pattern: the island’s 32 counties range dramatically in size, population, and character, with the smallest being roughly 11 times smaller than the largest.

This data table shows the island’s core geographical benchmarks.

Metric Value Source
Total area of Ireland 84,421 km² (32,595 sq mi) World Atlas Ireland mapping
Number of provinces 4 Greenway Hub county guide
Most populous county Dublin (1.4 million) World Atlas Ireland mapping
Least populous county Leitrim (32,000) Irish Genealogy Toolkit county guide
Highest point Carrauntoohil (1,038 m) in County Kerry World Atlas Ireland mapping

The pattern: Dublin dominates population while Leitrim anchors the sparsely populated northwest, a divide that recurs across economic and safety rankings.

What is the prettiest county in Ireland?

What is the most beautiful county in Ireland?

  • County Kerry is frequently cited as the prettiest due to the Ring of Kerry and Killarney National Park (Irish Genealogy Toolkit county guide).
  • County Clare and County Galway also rank high for natural beauty, with the Cliffs of Moher and Connemara drawing visitors from around the world.
  • Travel surveys from Lonely Planet travel authority and Condé Nast consistently place these counties at the top for scenic landscapes.

Which counties are often ranked as the most scenic?

  • The Ring of Kerry in County Kerry, the Burren in County Clare, and the Aran Islands off County Galway are three of the most photographed locations in Ireland.
  • County Donegal, with its rugged coastline and Slieve League cliffs, is also a strong contender in beauty rankings.
Bottom line: County Kerry, Clare, and Galway dominate beauty rankings, but the “prettiest” label remains subjective. For first-time visitors, Kerry delivers the most concentrated scenic payoff. For repeat travelers, Donegal and Mayo offer wilder, less crowded alternatives.
The upshot

County Kerry alone draws more than 1 million visitors annually to the Ring of Kerry—a stretch of road that packs more jaw-dropping views per mile than almost any other county in Ireland. If you have only three days, Kerry is the bet.

What is the poorest county in Ireland?

What is the poshest part of Ireland?

  • According to Central Statistics Office Ireland national statistical authority, County Donegal has the lowest disposable income per capita.
  • County Leitrim also ranks low in economic indicators, with a population of roughly 32,000 and limited industrial base.
  • The poshest area is often considered County Dublin (Dún Laoghaire-Rathdown) or parts of County Wicklow, where median incomes are significantly higher.

What is the most forgotten county in Ireland?

  • County Leitrim is frequently described as the most overlooked county, with the smallest population of any county in the Republic of Ireland.
  • County Longford and County Roscommon also appear on lists of counties that receive fewer visitors and less economic investment.
Bottom line: Donegal and Leitrim sit at the lower end of the income spectrum, while Dún Laoghaire-Rathdown leads on wealth. The gap reflects a broader urban-rural divide that shapes where people live, work, and invest in Ireland.
The trade-off

Lower-income counties like Donegal and Leitrim offer the lowest crime rates and some of the most stunning natural landscapes in Ireland. Residents trade earning power for quality of life and safety—a choice that shows up in every cost-of-living comparison.

What are the 32 counties in Ireland in order?

What are the four provinces of Ireland?

  • The four provinces of Ireland are Connacht, Leinster, Munster, and Ulster (Greenway Hub provincial guide).
  • Leinster has 12 counties, Munster has 6, Connacht has 5, and Ulster has 9 (Greenway Hub provincial guide).
  • Ulster is the only province that spans two jurisdictions: six of its nine counties are in Northern Ireland, and three are in the Republic of Ireland (Greenway Hub provincial guide).

Which counties are in Northern Ireland?

  • Northern Ireland comprises 6 counties: Antrim, Armagh, Derry, Down, Fermanagh, and Tyrone (Irish Genealogy Toolkit county guide).
  • The 26 counties of the Republic of Ireland are Carlow, Cavan, Clare, Cork, Donegal, Dublin, Galway, Kerry, Kildare, Kilkenny, Laois, Leitrim, Limerick, Longford, Louth, Mayo, Meath, Monaghan, Offaly, Roscommon, Sligo, Tipperary, Waterford, Westmeath, Wexford, and Wicklow (Irish Genealogy Toolkit county guide).

Six counties in Northern Ireland, 26 in the Republic—one pattern: the 32-county system remains the standard map view even though modern administrative boundaries have shifted.

This province table shows the breakdown at a glance.

Province Number of counties Counties
Connacht 5 Galway, Leitrim, Mayo, Roscommon, Sligo
Leinster 12 Carlow, Dublin, Kildare, Kilkenny, Laois, Longford, Louth, Meath, Offaly, Westmeath, Wexford, Wicklow
Munster 6 Clare, Cork, Kerry, Limerick, Tipperary, Waterford
Ulster 9 Antrim, Armagh, Cavan, Derry, Donegal, Down, Fermanagh, Monaghan, Tyrone

The implication: Ulster is the only province split across two jurisdictions, which means any county map of Ireland that shows all 32 counties needs to straddle both the Republic of Ireland and Northern Ireland boundaries.

What is the smallest county in Ireland by land?

What is the largest county in Ireland?

  • County Louth is the smallest at 820 km² (Irish Genealogy Toolkit county guide).
  • County Cork is the largest at 7,457 km² (World Atlas Ireland mapping).
  • Other small counties include County Carlow (896 km²) and County Leitrim (1,590 km²) (Irish Genealogy Toolkit county guide).

How does county size vary?

  • County Cork is roughly 9 times larger than County Louth.
  • The five largest counties by area are Cork, Galway, Mayo, Donegal, and Kerry.
  • The five smallest are Louth, Carlow, Leitrim, Monaghan, and Sligo.
Bottom line: County Louth fits into County Cork more than 9 times. For travelers, that means Cork demands a week to explore properly—Louth can be done in a day.

Which is the safest county in Ireland?

What are the crime rates in Irish counties?

  • According to CSO crime statistics Ireland’s official data authority, County Leitrim and County Roscommon consistently report the lowest crime rates.
  • County Mayo and County Sligo also rank highly for safety, with low rates of burglary and public order offenses.
  • Urban areas like Dublin and Cork have higher crime rates—particularly in theft and anti-social behavior categories—but are still generally safe by international standards.

Are there any counties with particularly low crime?

  • Leitrim and Roscommon routinely appear at the top of safety rankings, with annual crime rates well below the national average.
  • Rural counties in the west and northwest tend to have the lowest crime figures, while urbanized counties in the east and south report higher numbers.
Bottom line: Leitrim and Roscommon are the safest counties by a clear margin. For families or retirees prioritizing safety, the northwest corridor from Leitrim through Mayo offers the most secure living environment in Ireland.
What to watch

Safety rankings depend heavily on which crime category you prioritize. Leitrim leads on low burglary rates, but Dublin’s city center has a higher concentration of pickpocketing and theft. The safest county for one person may not be the safest for another—check the specific crime type that matters to you.

“County Donegal has the lowest disposable income per capita of any county in the Republic of Ireland, according to our latest regional income analysis.”

Central Statistics Office Ireland national statistical authority

“The Ring of Kerry and Killarney National Park make County Kerry one of the most beautiful places on the planet, drawing visitors from every continent.”

Lonely Planet travel authority

“County Leitrim and County Roscommon consistently report the lowest crime rates in Ireland, making them the safest counties to live in.”

CSO Crime Statistics Ireland’s official data authority

The pattern across all three rankings—beauty, income, and safety—is that Ireland’s western and northern counties dominate the top of both the prettiest and safest lists, while also appearing at the lower end of the income scale. For anyone choosing where to visit or settle in Ireland, the trade-off between scenery and income is the central decision.
