Car Ownership in Ireland: How Every County Compares
Quick answer
Roscommon has the most private cars per person in Ireland (620 per 1,000), Dublin the fewest (442 per 1,000) — the opposite of what car ownership looks like in most countries, where cities have more cars, not fewer.
The pattern: fewer cars in Dublin, more in rural counties
Ireland had 2,612,353 private vehicles registered as of September 2026. Spread per person, that works out to very different numbers depending on where you live.
Dublin has the lowest car ownership rate in the country: 442 vehicles per 1,000 people. Roscommon has the highest, at 620 per 1,000 — 40% more cars per head than Dublin. Wexford (596) and Carlow (567) aren’t far behind Roscommon.
This is the reverse of what you’d see comparing cities and rural areas in most of the world, where car ownership tends to rise with distance from a city, not the other way round within one country’s capital. It isn’t really reversed, though — it’s the same pattern everywhere: Dublin is the one place in Ireland where public transport, cycling and walking are realistic substitutes for a car for daily life. Everywhere else, there usually isn’t a bus that gets you to work on time, so a household needs its own car, often more than one.

Dublin doesn’t just have fewer cars — it has different ones
Nationally, the fleet is diesel-dominant: 47.6% of all private cars on the road run on diesel, 33.2% on petrol. Dublin flips that: petrol is Dublin’s largest fuel category at 42.0%, ahead of diesel at 29.8%.
Dublin also has the country’s highest electric vehicle share, at 8.0% of its private fleet, against a 5.4% national average. Part of this is simply that EVs are newer and more expensive on average, and Dublin has the country’s highest incomes and shortest commutes — the two things that make an EV’s higher purchase price and limited range least of a barrier.
What this doesn’t tell you
These are stock figures — the vehicles on the road right now — not sales. A county with an older fleet and low turnover can look very different from one with high new-car sales but also high scrappage.
