In an effort to understand some of the key factors in the current hotel industry, I created a data set with the top 5% most expensive hotels and mapped their locations to determine which regions had the highest density of “exclusive” hotels. As it was to be expected the usual suspects are at the top of the list: London, Tokyo, New York City, Paris, Rome. The rest of the list has a good mix of modern, beach and historic cities: Venice, Miami, Los Angeles, Milan, Moscow, Florence, Cape Town, Osaka, Morocco, Maui, Cancun, Washington, Bali, Madrid. London has over 120 exclusive hotels while Madrid counted 20. Beyond that these exclusive hotels are scattered around the world. These images provide a general view of where in the world they are: ……

From the analysis of the recent Competitiveness 2009 report we can even derive that some regions will have to try much harder to compensate for factors such as dependency from long-haul passengers.

In an effort to understand some of the key factors in the current hotel industry, I created a data set with the top 5% most expensive hotels and mapped their locations to determine which regions had the highest density of “exclusive” hotels.

……

While calculating these “exclusivity hubs” I came across some other interesting facts:

• The five regions where the top 5% is far more expensive than in the rest of the world are: United Arab Emirates, Morocco, South Africa, New Zealand and Switzerland
• The currencies that will buy you more exclusivity for less are the Japanese Yen, Polish Zloty, Mexican Peso, Canadian Dollar, Indian Rupees, Chinese Yuan and Brazil Reais
• US$264/night will get you into one of these properties

It’ll be interesting to see how this group changes as the year advances and hotels fail to meet their quotas. I’m planning to release a lot more of this analysis as part of a new set of travel guides we’re producing at PlanetEye, but if you’re interested in the numbers behind please drop me a line.

A zeitgeist reflecting the drama of our times:

1. Washington,DC

its not really about the Obamas – its about the context of our changing expectations of government

2. Berlin

Berliners become an enigma – povo at home, increasingly affluent abroad

3. Beijing

Just ignore the noxious skyline as you watch the GDP growth rates, still hovering near 9%

4. Los Angeles

LA’s fashion scene has stagnated, and the city’s hold on entertainment is slipping to diffusion by web 2.0

5. Tokyo

the principles of kaizen (continuous improvement) are shaping a really cool new Japanese ecovibe

6. Sydney

The general attitude down under appears to be one of distant concern

7. Saö Paulo

Here, ‘crunch’ is in the quinoa, not in the financial vocabulary

8. Hong Kong

The city is rich enough to sit out the bust, and it can always rely on China’s neighboring Guangdong province to drive the local economy

9. New York

Hunger breeds innovation, because people actually have to think, plot and scheme to make a difference, and are more likely to do it on a shoestring budget.

10. London

With large infrastructure projects on the horizon for the Olympics, nimble currency moves and a general stiff upper lip, the mantra now is survival and sobriety

11. Shanghai

China is one of the last places in the world still experiencing growth, and that means that the party is still in progress here on the Huangphu River

12. Mumbai

Clearly the November attacks had a large impact on the mood of the city, but they can’t dent the can-do spirit of average Mumbaikars

13. Singapore

Private wealth and trading (two of the city’s biggest focuses) are giving ground to medical tourism, biotech and other homegrown industries taking root with support from the government

14. Buenos Aires

international markets and visitors that provide an international feel to the city began to dry up

15. Dubai

Dubai’s taste for showcases, whether luxury, architecture or design, make the remaining grand opportunities here very interesting

16. Paris

The current mood is about refocusing on priorities, living life more simply and thinking deep thoughts. Where better than Paris?

17. Toronto

Canadian globe trotters are heading back home to Canada’s most influential business city as they check out of their stints abroad.

18. Istanbul

Looking ahead, the story of Istanbul is about youthful opportunity.

19. México, D.F.

a young population works in Mexico City’s favour, creating optimism and opportunity for the future, generated by an increasingly well educated and global population.

20. Copenhagen

the Danish way of life, from design to food, with a focus on streamlined simplicity, makes more sense than ever.

Other cities outside of North America included in the list: Osaka, Madrid, Sydney, Amsterdam, Paris, Melbourne, Berlin, Bangkok, Barcelona, Taipei, Santiago, Dublin and Caracas.

and the rest of the list.

With the recent opening of the Art Gallery of Ontario, a controversial renovation of the Royal Ontario Museum and a brand new Centre for the Performing Arts, us Torontonians have forged our way into the top 10. But it makes you wonder how much this type of top 10 lists can fluctuate when you start adding other factors as part of the ranking such as:

The methodology to rank the cities includes 24 metrics in five dimensions:

The first is business activity: including the value of its capital markets, the number of Fortune Global 500 firms headquartered there, and the volume of the goods that pass through the city. The second dimension measures human capital, or how well the city acts as a magnet for diverse groups of people and talent. This includes the size of a city’s immigrant population, the number of international schools, and the percentage of residents with university degrees. The third dimension is information exchange—how well news and information is dispersed about and to the rest of [...]]]> In January of 2007 I posted the globalization index, a partnership between Foreign Policy magazine and A.T. Kearney. At the time the report listed the most globalized countries, led by Singapore, Switzerland and the United States. A few weeks ago I decided to once again fine tune the editorial line of this blog by dedicating more time to cover urban issues and the role of cities in the shaping of our global culture. So finding the Foreign Policy’s 2008 Global Cities Index serves to reinforce the recent spirit of this blog.

The methodology to rank the cities includes 24 metrics in five dimensions:

The first is business activity: including the value of its capital markets, the number of Fortune Global 500 firms headquartered there, and the volume of the goods that pass through the city. The second dimension measures human capital, or how well the city acts as a magnet for diverse groups of people and talent. This includes the size of a city’s immigrant population, the number of international schools, and the percentage of residents with university degrees. The third dimension is information exchange—how well news and information is dispersed about and to the rest of the world. The number of international news bureaus, the amount of international news in the leading local papers, and the number of broadband subscribers round out that dimension.

The final two areas of analysis are unusual for most rankings of globalized cities or states. The fourth is cultural experience, or the level of diverse attractions for international residents and travelers. That includes everything from how many major sporting events a city hosts to the number of performing arts venues it boasts. The final dimension— political engagement—measures the degree to which a city influences global policymaking and dialogue. How? By examining the number of embassies and consulates, major think tanks, international organizations, sister city relationships, and political conferences a city hosts.

The complete ranking breaks down the position of each city in each dimension, but here is a preview of the overall winners:
New York – London – Paris – Tokyo – Hong Kong – Los Angeles – Singapore – Chicago – Seoul – Toronto – Washington – Beijing – Brussels – Madrid – San Francisco

The index, a collaboration between Foreign Policiy, A.T. Kearney and The Chicago Council on Global Affairs, includes a few other features such as how to be a global city, the placement of the 19 megacities in the index, the massive role of Chinese cities, an unexpected relationship between most global and cleanest urban centres and more.

The Monocle Global Quality of Life Index may one day graduate to adopt a scientific methodology that considers a larger spectrum of cities around the world, but I’m happy to settle for their current coverage and play the my-city-is-better-than-yours game, using the tidbits of quick facts they’ve compiled. For those who don’t buy the magazine here are the top 10 cities:

Since my last post I travelled to Mexico twice, shared the stage in San Francisco with some of the authorities on the “geoweb”, travelled to Corsica, the French Riviera, Lake Como, St. Moritz; and managed to launch PlanetEye.com where I lead the Technology team. Intense to say the least. But the most recent issue of Monocle has me burning the proverbial midnight oil and finding energy to start posting regularly again. Thanks for your comments while I was away.

The Monocle Global Quality of Life Index may one day graduate to adopt a scientific methodology that considers a larger spectrum of cities around the world, but I’m happy to settle for their current coverage and play the my-city-is-better-than-yours game, using the tidbits of quick facts they’ve compiled. For those who don’t buy the magazine here are the top 10 cities:

1. Copenhagen, Denmark

Good looks, brains, perfect proportions, a sunny disposition and a sense of humour are always a winning combination…

2. Munich, Germany

It combines a strong economy with rich cultural offerings. The city’s workforce is highly qualified; its universities world class. And if the walls start closing in you’ve got the Alps on your doorstep.

3. Tokyo, Japan

… a new generation of well-travelled, job-hopping twenty and thirtysomethings who are changing Tokyo, challenging stereotypes…

4. Zürich, Switzerland

The city’s world-class education facilities and cultural offerings, great local public transport and well-connected airport mean it can satisfy even the most demanding employees.

5. Helsinki, Finland

Waterside revival, civic pride and a view to Asia bode well for the city…

6. Vienna, Austria

Don’t be deceived by Vienna’s apparent bourgeois rectitude…

7. Stockholm, Sweden

… with its archipelago, pristine parks and old architecture, is pretty as a princess cake – the Swedes’ favourite birthday treat.

8. Vancouver, Canada

By accepting increased building density as official city policy, Vancouver believes it is leading the continent in addressing climate change.

9. Melbourne, Australia

its economy is humming, its arts scene is thriving, and more than 1,000 new people a week are calling the city home.

10. Paris, France

…it is setting benchmarks in urbanism that have officials from around the world heading to meet mayor Bertrand Delanoë.

Sydney, Honolulu, Madrid, Berlin, Barcelona, Montréal, Fukuoka, Amsterdam, Minneapolis, Kyoto, Hamburg, Singapore, Geneva, Lisbon and Portland follow the leaders.

But the ranking is just a great marketing tool. Much more interesting and relevant to the readers of this blog are the articles “Thinking cities” which collects ideas from some of the best recognized urban thinkers; and “Perfect neighbourhood”, a redux of their ideal borough dream from last year. More on this in upcoming posts.

In some ways, the doom and gloom LA has experienced recently has presaged the general red alerts now being felt elsewhere – from environmental crisis to economic lapse, LA seems to have arrived in the shits just before everyone else.

As the cutting edge vibe in London wanes, Berlin continues to draw the young and the restless, and its ties to a resurgent East (i.e. Moscow, Warsaw) are really showing dividends.

Even as Mumbai gridlock threatens to become a 24/7 state of affairs, India in general and Mumbai in particular continue their assault on the global consciousness. It’s hard to argue against Mumbai, especially with so many [...]]]> Every year Stan Stalnaker and his team of global citizens gather their experiences around the world and summarize in this, their now famous Hub Culture’s Zeitgeist Ranking, the cities that for a variety of reasons seem to be at the center of the Universe. An elusive classification that doesn’t get impressed with economic power, flawless life-styles or centuries-old traditions, is mostly based on heuristics that related to the needs and desires of global citizens hoping from hub to hub networking their way into urban authorities. This is their veredict:

1. Los Angeles, United States

In some ways, the doom and gloom LA has experienced recently has presaged the general red alerts now being felt elsewhere – from environmental crisis to economic lapse, LA seems to have arrived in the shits just before everyone else.

2. Berlin, Germany

As the cutting edge vibe in London wanes, Berlin continues to draw the young and the restless, and its ties to a resurgent East (i.e. Moscow, Warsaw) are really showing dividends.

3. Mumbai, India

Even as Mumbai gridlock threatens to become a 24/7 state of affairs, India in general and Mumbai in particular continue their assault on the global consciousness. It’s hard to argue against Mumbai, especially with so many new innovations popping up here. That includes the arrival of the TATA Nano, which will soon change the economics of transport across the developing world. Add in booming hotels, real estate and a stronger rupee, and Mumbai holds the course.

4. Beijing, China

2008 is Beijing’s year, and not just because of the Olympics. The financial meltdown occurring in other capitals has cast Beijing in a new light as the Chinese continue to show fiscal reserve while strengthening their own position.

5. Tokyo, Japan

Tokyo is steaming! A combination of low prices, an awakening in the real estate sector, smart yen plays and new innovation in the music scene have breathed new life into Asia’s sleeping Godzilla.

6. London, United Kingdom

Overpriced by any measure and past the crest in nightlife, London seems to have dulled in line with the smaller bonuses being handed out in the City.

7. Buenos Aires, Argentina

BA has problems, but Argentina’s cheap prices are attracting legions of globalized people, especially financial types looking to make investments in everything from wine to hotels.

8. Dubai, U.A.E.

Global investment capability and a city awash in cash and construction make Dubai one of the world’s few economic bright spots in 2008.

9. New York, United States

While not great for the locals, that makes for a wonderful hub moment in the city: a bargain for visitors and a place more remarkably open and international than it has been for a long time.

10. Hong Kong, China

The scene remains predictable, but predictably fun, and Hong Kong’s leadership in fashion and Asian pop culture is steady – even if everyone is increasingly obsessed with Korean daytime TV.

11. Istanbul, Turkey

Istanbul has dropped from last year – not because it is any less hot, just because other locations are now taking up more mind space. As the Islam threat feels like its cooling Istanbul continues to set the leadership example for the region while integrating ever closer to Europe.

12. San Francisco, United States

San Francisco continues to punch above its population weight, mostly because it continues to reinvent itself. From the technology space it is now leading the global green charge, spearheading investments and opportunity in the sector.

13. Sao Paolo, Brasil

Brazil’s macro success is manifesting in booming design, nightlife, and real estate in South America’s largest city with a young, increasingly educated, party population.

14. Shanghai, China

The city has recently blossomed and is now genuinely a fun place to live, filled with interesting people, a cosmo scene and true cultural innovation.

15. Moscow, Russia

Putin was named TIME’s Man of the Year for a reason: Moscow continues to grow its sphere of global influence, and instead of saber rattling the new vogue is suitcase rattling: as in suitcases of cash.

16. Madrid, Spain

Sunny Madrid is benefiting from stability and language. As South America continues to do well, Madrid benefits back in Europe, and a continuing influx of Northern Europeans adds to the cultural mix. Add in some of the best nightlfe in Europe, a hot art scene and lower living prices than other regional hubs, and Madrid looks ever more enticing.

17. Singapore, Singapore

Whether stepping up to the financial plate globally or announcing another outlandish designer building project, the tiny city state continues innovation at the macro level, providing economic security and iced whipped chai for its people in an ever more turbulent world.

18. Sydney, Australia

Sydney is the terrycloth towel of urban hubs – rich, beautiful and soft enough to feel comfortable. In a land aloft in buoyant commodity prices and closer ties with the economic engines of Asia, some would argue Sydney never had it so good.

19. Mexico City, Mexico

The worlds largest city remains a study in contrasts, but times are so good that Mexican immigrants are even returning from California to seek opportunity in Mexico City. The city elite are still preoccupied with gringonomics to the north, but local growth and development auger well. Add in the city’s super young vibe, and one gets the feeling anything is possible.

20. Vancouver, Canada

Vancouver gets this year’s wild card, in the spirit of No. 10 Geneva last year. A combination of factors are benefiting this coastal hub, ranging from preparations for the 2010 Winter Games in nearby Whistler to an avalanche of business in the film industry on the heels of LA woes. Clean and pristine, Vancouver sums up the new environmental feel, and that strong Canadian dollar has Vancouver strutting its stuff in a newly confident way, from Seattle all the way to Shanghai.

A year is a long time and many cities have fought battles for the attention of this elite crowd. Take a look at the now obsolete 2007 ranking.

With a well documented rating behind each one of the cities in the list, it is going to be hard to argue that they’ve done their homework, but it still feels very subjective. In any case, [...]]]> Hyper-connected to the rest of the world through an ample offering of long-haul flights, low crime rates, great education and health system, fair balance of sunny and warm days, plenty of ways to stay informed, availability of drinks after hours, good public transit, lots of green areas and a will to keep them green. This is the method behind the first Monocle Quality of Life Index.

For international flight connections it would be Paris but for an airport it would have to be Munich. On crime it would be a Japanese city – either Tokyo or Kyoto would do. Zürich and Helsinki would be our key contributors for hospitals and schools while Sydney and Honolulu offer the best weather. [...] For a good night out we’d want to be resident in Madrid, Tokyo or Barcelona and for getting home we’d opt for Munich’s public transport and Copenhagen’s bike network if we were sober enough to pedal home ourselves.

With a well documented rating behind each one of the cities in the list, it is going to be hard to argue that they’ve done their homework, but it still feels very subjective. In any case, kudos to the top 10 cities:

1. Munich, Germany

A winning combination of investment in infrastructure, high-quality housing, low crime, liberal politics, strong media and general feeling of Gemütlichkeit make it a city that should inspire others.

2. Copenhagen, Denmark

There’s no shame coming second, particularly when phase two of your new metro is about to go live, your airport is a joy, you can bike safely through the city and you have so many stunning residents.

3. Zürich, Switzerland

for being one of the best-connected, best endowed, safest and easiest to navigate cities in the world [...] run one of the most high-frequency public transports networks in the world and boast a bathing culture that sees the trimmest bodies at Bank Julius Bar strip off at lunch for a cooling plunge in tis mountain-water-fed lake.

4. Tokyo, Japan

Integrated transport, breathtaking technology, great service and the best bars make this our top big city.

5. Vienna, Austria

famous for its rich cultural heritage, also has a progressive eco-friendly municipal government.

6. Helsinki, Finland

What’s lost in the winter darkness is replaced by great cultural and sporting outlets, Stockmann’s bookstore and a good music scene.

7. Sydney, Australia

The city has some environmental issues and an antiquated trasnport system. But then there’s the beach…

8. Stockholm, Sweden

An eye for detail, good street style and strong public services make this a pleasant place to build a nest.

9. Honolulu, United States

Bridging the oceanic gap between California and Asia, Honolulu now fits the definition of a global city – a palm-fringed metropolis with a population as diverse as its flora.

10. Madrid, Spain

Red tape and poor infrastructure are counterbalanced by cultural vibrancy and a 24-hour lifestyle

Melbourne, Montreal, Barcelona, Kyoto, Vancouver, Auckland, Singapore, Hamburg, Paris & Geneva follow the leaders with their own advantages in this ranking, which along the rest of the magazine does a lot to uncover great urban experiences.

I’ve posted other rankings that measure cities against each other and Monocle’s approach is certainly interesting but with the growing global awareness many of the advantages that some of these cities hold will soon be replicated and enjoyed in tandem by citizens of most global cities. Perhaps it is the article Good Hood found in the pages that follow the ranking that offers a greater insight as to what makes a true liveable city: plenty of neighborhoods with the diversity and vibrancy to keep their inhabitants satisfied with a range of local world-class services. For all other goods of life you can always aspire to your next adventure abroad.

Thanks to Slava for recommending the magazine. It is a great discovery.

Wonder where your city ranks among these? Consider the following facts: Broadband is available in four out of five Seoul households and costs just $40 a month for speeds up to 100Mbps. Nine out of 10 residents also have mobile phones. [...] Digital mobile TV broadcasting, or Digital Multimedia Broadcasting, was launched in South Korea in 2005 and nearly 2 million Koreans now use the service to watch TV on their phones while riding trains and buses.

Last December the Singapore Government said it would roll out free wireless broadband across the island and more than 400,000 Singaporeans already have registered for the service. The government also plans to deliver wired broadband speeds of up 1Gbps by 2012.
