Who lives in Dublin
Dublin is Ireland's most international city: around one in six people in the county holds no Irish citizenship, with the largest groups coming from Poland, India, Brazil and Great Britain. The most diverse patch is Parnell Street East, with supermarkets and restaurants from all over the world. If you're after the real Dublin, skip the obvious address – Temple Bar is one of the biggest tourist traps anywhere; locals head instead for pubs like Mulligan's or Kehoe's, and neighbourhoods such as the Liberties, Portobello or Howth (more in the Food & Drink guide).
The religious landscape is also shifting fast: the share of Catholics nationwide fell from 79 per cent (2016) to 69 per cent (2022), while Muslim, Orthodox and Hindu communities are growing. The Catholic roots feature in the Dublin churches guide, and the wider cultural heritage in our piece on Irish traditions and customs.
Economy – Silicon Docks, pharma, Guinness and tourism
Dublin is one of Europe's wealthiest economic regions; the area generates over 40 per cent of Ireland's GDP. Four pillars stand out:
- Tech: 16 of the world's 20 biggest tech companies have a presence in Ireland. Around Grand Canal Dock – the "Silicon Docks" – sit the European headquarters of Google, Meta, Amazon, LinkedIn and Stripe; Google alone employs around 8,000 people in Dublin.
- Pharma: the export engine – medical and pharmaceutical products made up over half of Ireland's goods exports in 2025.
- Brewing: dating back to Arthur Guinness's 9,000-year lease of 1759 at St. James's Gate. The Guinness Storehouse there has been Ireland's most-visited paid attraction for 15 years running (around 1.65 million visitors in 2024).
- Tourism and transport: Ireland recorded around 6.16 million overseas visitors in 2025, with Dublin as the main gateway – and home to Ryanair, Europe's biggest airline (headquartered in Swords; practical details in our Flights and Dublin Airport guides).
You can see this economic shift for yourself in the Docklands: Grand Canal Square is home to Daniel Libeskind's Bord Gáis Energy Theatre and the award-winning EPIC The Irish Emigration Museum; down by the water, the Famine Memorial and the tall ship Jeanie Johnston recall the story of emigration.
Costs – Dublin isn't cheap
Housing shapes everyday life for Dubliners: the average rent for a two-bedroom flat stood at around €2,600 in early 2026, with less than one per cent of rental homes available. Numbeo ranks Dublin among Europe's priciest cities – pricier than Amsterdam or Berlin, cheaper than Paris or Zurich. For visitors, that mostly means higher hotel and restaurant prices; see the Where to stay in Dublin guide for tips on picking a neighbourhood that suits your budget.
Climate & best time to visit
Dublin has an oceanic climate – mild, but rainy and changeable year-round. The coldest months are January and February (2 to 8°C), and the warmest is July (up to 20°C by day). May to September brings the mildest weather; the city is busiest in July, August and December, and quietest in January and February. Pack a rain jacket whatever the season – full details and packing tips in our Dublin weather guide.
Getting in from the airport
Dublin Airport (DUB) lies roughly 17.5 kilometres north of the city centre (a 25- to 40-minute journey); there's no rail link.
- Regular TFI buses (including routes 16 and 41) – the cheapest option, fully integrated into the fare system
- Express coaches Dublin Express and Aircoach – stop at central points such as O'Connell Street and Heuston Station
- Taxi – typically €25 to €40
Full routes and stops are listed on our Dublin Airport page.
Getting around
Buses, the Luas tram and the coastal DART rail line are all covered by the contactless TFI Leap Card: a 90-minute journey costs €2 (adult fare), up to 30 per cent less than paying cash. Details in the Leap Card guide and our public transport overview.
Living history and culture
Dublin's history – from the Vikings to the fight for independence – is written into the cityscape: the General Post Office was the headquarters of the 1916 Easter Rising, Kilmainham Gaol is where 14 of its leaders were executed, and walking tours of the Rising set off from Trinity College. Alongside that history, the Abbey Theatre (since 1904) and Gaiety Theatre (since 1871) keep the stage traditions alive; the Dublin Theatre Festival runs from 24 September to 11 October 2026 – more dates on our events page.
Safety & how long to stay
Dublin is a safe destination to visit; pickpocketing is concentrated in tourist zones such as Temple Bar and Grafton Street (tips on our safety in Dublin page). Two days cover the highlights – Trinity College, Christ Church, the Guinness Storehouse; add museums like EPIC and day trips to Howth or the Wicklow Mountains and three to four days rounds things out nicely.
