“Smart” cities herald a new age where information technology, not roads, buildings or bridges, will form the core infrastructure. A network of sensors, cameras, wireless devices, data centres and powerful analytics will enable the government to provide more efficient services, maintain a low carbon footprint and create an entrepreneurial environment for its citizens. Given the potential for such intelligent governance, cities with digital infrastructures are called “smart” cities. Today, there are over 125 smart city projects of varying sizes all over the world, including new cities like Songdo in South Korea and Masdar in the UAE, and existing cities like Stockholm and Rio de Janeiro.

This survey is not based solely on quality of life, number of trees or the cost of a month’s rent. Instead, we examine some cities that aim to be both smart and well managed, yet have an undeniably hip vibe. Our pick of cities that are, in a phrase, both great and good:

I spoke to Joel Kotkin, a professor of urban development, and asked him about these surveys. “I’ve been to Copenhagen,” (Monocle’s Number 2) he tells me “and it’s cute. But frankly, on the second day, I was wondering what to do.” So, if the results aren’t to his liking, what does he suggest? “We need to ask, what makes a city great?

Descartes, writing about 17th-century Amsterdam, said that a great city should be ‘an inventory of the possible’. I like that description.”

We hope, in some small way, we can help re-enchant the urban environment as a landscape of possibility, a realm of action and intention, and a place that represents — and deserves — a long and evolving history of creative ideas.

Between 2000 and 2010, new suburbs sprung up in unholy rings around the U.S.'s major cities, but these maps show that a tiny heartbeat of life is still resurgent in urban centers.

But whatever the genuine threats to urban prosperity, human contact is more important than ever in the age of information technology, and people will continue to seek places where they can share ideas, make transactions, and pursue their dreams. There’s nowhere better to do these things than big cities.
