The world is full of incredible cities, all bursting with qualities that make them stand out from the rest. But what would the perfect city look like? We take a look at what the ideal metropolis would be made up of from the world’s cities today.

Despite its large oil and gas industry, Calgary is still considered to be the world’s cleanest city. According to research by the Blacksmith Institute and Green Cross Switzerland, the Canadian city’s reputation has a lot to do with its well-planned out, grid-like structure that helps to reduce traffic congestion and pollution. It also has a number of transfer stations that sort through trash and organise recyclable materials to keep litter off the streets.

Generally speaking, the smaller the city, the better and shorter the commute. That’s why commuting in Hong Kong, which is one of the densest and geographically-smallest cities in the world, is such a dream. Research by Hong Kong Polytechnic University has shown that most jobs are based on Hong Kong Island, which is connected to the rest of the city by bus, ferry and rail systems, used by 90% of residents, so they’ve well and truly got it under control.

According to data by the World Health Organization, France is the best country in the world to receive healthcare. This is mainly due to its state-run system that requires patients to pay their practitioner upfront, but then reimburses them in part or in full.

It’s all well and good having a perfect-looking city, but you need to be able to afford to live there. The good news is that having house prices similar to that of anywhere in Japan would mean the cost of buying and renting would be much lower. OECD data shows Japan has the most profitable and affordable housing of all the OECD countries, with a price-to-income ratio of -38.4, compared to Belgium, which has the highest ratio of 46.6 (the higher the ratio the more overvalued the property).

Research conducted by dospeedtest.com revealed the capital of South Korea has the world’s fastest internet speed. This is perhaps unsurprising for one of the most technologically advanced countries in the world. It has a download speed of close to 23Mbits/s, while the worldwide average generally hovers around the 13Mbits/s mark.

With working hours averaging just under 31 per week, France’s capital leads the way with the best work/life balance. Total working hours only average 1,604 hours a year – that’s almost 18% less than the global average. This leaves the lucky Parisians plenty of time to enjoy their beautiful city.

From the cultural diversity of London and New York City, to the array of high-low dim sum mash-ups in Hong Kong, the world’s capitals know how to put on a good spread. But the Mother City’s easy pace of life and cosmopolitan culture rubs off on the food, producing some of the freshest and most interesting dishes from around the world. It’s not all biltong and bobotie, either; seafood, amazing tapas and regional wines give this city such a good culinary reputation.

Known as the “water tower of Europe”, if every city had drinking water as fresh and pure as Switzerland, the world would be a much healthier place. Due to its perfect Alpine surroundings and strict regulations around drinkable water, the perfect city would drink from the taps of any Swiss city.

Forget the red light district and coffee shops, Amsterdam is home to an abundance of other nocturnal activities to excite every night owl. This city boasts a selection of top-notch clubs with a spectacular clutch of cabaret, modern jazz and techno nights. What perfect city wouldn’t want to steal a bit of the party?

While there are hundreds of places with sunshine all year round, not everybody defines good weather as blazing sunshine and sticky humidity 365 days a year. San Diego, however, has got it just right. The US city has around 300 sunny days every year and receives an average temperature of 76°F (24°C) during the hot season and 57°F (14°C) in the winter, meaning the city retains a gorgeously mild climate all year round.

New York City, London and Tokyo may be among the best cities in the world, but busy lives don’t leave much time for friendliness. Over in Charleston, South Carolina, however, the whole city is basking in traditional Southern charm and people are, according to Condé Nast Traveler readers, the friendliest in the world.

The Swedish government has the most generous parental leave in the world – mothers and fathers are entitled to 480 days of paid leave (90 of which are reserved for dads), as well as subsidized childcare. But, more than just the benefits and perks, Stockholm is also one of the best cities to raise children due to Sweden’s passion for human rights, gender equality, income equality, safety and happiness levels. The well-developed education system is also a huge factor.

From galleries packed with famous paintings to West End theaters to the English National Opera to Shakespeare’s Globe, there is something to please every culture vulture in London.

The perfect city couldn’t be without it.

With a goal to be carbon neutral by 2025, Copenhagen has some seriously advanced environmental policies and planning. One of the world’s most liveable cities has a population of just two million, but has an infrastructure designed to encourage cycling and walking rather than driving.

From the unfinished symphony that is La Sagrada Família to Park Güell, Barcelona is an architect’s paradise thanks to Antoni Gaudi and his distinct style, which is showcased all over the city. But to locals, the city is about so much more than just Gaudi. Other architects have followed in his experimental footsteps and have continued to fill the city with colorful, brash and unique buildings that blend the old and new. There isn’t anywhere quite like it.

With over 100 museums dotted all over the city, and the likes of the National Air and Space Museum, the National Gallery of Art and the National Museum of Natural History featuring on numerous lists of the best in the world, when it comes to indulging in a bit of history DC is the place to go.

Whether you’re a Sex And The City fan or not, everybody knows just how fantastic shopping can be in NYC.

Street food has taken over the world in recent years, with new and innovative food trucks popping up all over the place.

For the fourth year in a row, Denmark was revealed as the least corrupt country in the world, according to data from Transparency International’s annual Corruption Perceptions Index (CPI). It’s consistently applauded for demanding transparency within its government and increased corporate responsibility, meaning it is one of the most desirable cities to work in the world.

London is home to the most billionaires worldwide, so it may not be surprising that it is also a hub for finance and international business. A recent PwC report revealed the Big Smoke is now the best city in the world for new job opportunities. Some of the most in-demand jobs are senior executives, doctors, and marketing and sales directors, all of whom would find highly-paid jobs here.

While many Scandinavian and Western countries have impressive education systems, Singapore tops the list. Results from the Programme for International Assessment (Pisa) revealed the Asian country receives the best academic results in maths, science and reading almost consistently. The methods of teaching are among the best as Singapore only selects its teachers from the top 5% of education graduates.

Not only is Prague hauntingly beautiful, with gothic architecture, cobbled streets and some of the best Christmas markets in the world, but it’s also one of the cheapest cities to live in. While cities like Mumbai are technically much cheaper, Expatistan's Cost of Living Index of the most liveable cities shows Prague is one of the most affordable in the developed world, with average living costs standing at around $350-$750 (£275-£590) per month including accommodation.

It’s pretty hard to define what makes a city most fun.

It has been the city of love for years, and according to online dating website WeLoveDates.com this isn’t changing.

The city with the world’s fastest broadband is also the happiest place in the world. And not just because it can get online in less than a second either. A report by Arcadis found Seoul is the happiest city due to its wealthy, healthy and crime-free culture.

Sydney is surrounded by dozens of beautiful white sandy beaches, including the world-famous Bondi Beach, tranquil bays and coves in Sydney Harbour, and some of the best surfing beaches in the world. Any city would be lucky to have such easy access to beaches like this.

Living in a city can be pretty overwhelming at times, and so there’s nothing better than taking a stroll in a park and being surrounded by green space for a while. With over 120 square meters of greenery, the Austrian capital has more parks than London and Amsterdam combined.
