How much beer will a dollar buy you in Dublin, London, Sydney?

If you like cheap beer, avoid New York and hit Prague instead. If you resent paying through the nose for public transport, don’t go to London. And avoid Dublin too.

We complain a lot in Ireland about the cost of things, but according to Expatistan's Summer 2015 cost comparison report, we're not faring too badly compared with other major cities. Dublin is ranked as the 28th most expensive city worldwide (down from 26th last year), and number 10 in Europe.

The international survey is based on contributions from people around the world, and measures costs such as: how far you can travel for $1 worth of petrol, or how much beer you can drink for the equivalent of $1.

Zurich emerged as the world's priciest city, 49 per cent more expensive than Dublin, followed by Geneva and Grand Cayman in the Cayman Islands.

While Dubliners get slightly more beer for their euro than Londoners or New Yorkers, the €5.78 Expatistan users report paying for a pint in Dublin is 22 per cent more than in Sydney, and 412 per cent more than in Prague.

Public transport is also much more expensive in Dublin than in many other major cities. A monthly pass costs the most in London, at the equivalent of €184, but Dubliners report paying €122 per month, ahead of New York (€105), Toronto (€96), Sydney (€90) and Brussels (€50).

Expatistan.com collects prices for everyday items and living costs from people living in every city in the world. Since 2009, more than 1.2 million prices have been submitted from 340,000 contributors based in almost 2,000 cities in 200 countries.

That’s a heck of a lot of data, but the website simplifies things by ranking the overall cost of living in each city based on the prices provided by users. It also allows users to compare costs in particular cities. To keep the data current, the most recent prices are given greater weight.

So how do prices in Dublin compare to some of the most popular cities for Irish emigrants worldwide?

Think Dublin is pricey? Then stay well away from London, which is 47 per cent more expensive than the Irish capital and the fourth most expensive city in the world, according to Expatistan. Food will cost you 16 per cent more, and clothing 19 per cent more, but the biggest difference comes in the cost of housing; average monthly rent for a two-bed apartment in an expensive area will cost about £2,468 (approximately €3,500) in London, 113 per cent more than the €1,663 you could expect to pay in Dublin. Transport costs are also much higher; a monthly public transport pass will set you back £128 (€184), 59 per cent more than the €116 Dublin residents report paying, while a litre of petrol is 26 per cent more expensive than Dublin at £1.25 (€1.80).
