Ever since Fred Astaire and Ginger Rogers appeared in the 1933 film Flying Down to Rio, the world has been fascinated with Rio de Janeiro. Popular perception of the city is infused with images of starry-eyed youngsters dancing into the dusk, backed by imposing mountains and dark sea.
That view has propelled Rio to the top of our list of the world's happiest cities. Famous for its annual Carnaval festival (starting Feb. 13 next year), the second-largest metropolis in South America finished first among 50 cities in a recent survey conducted by policy advisor Simon Anholt and market researcher GfK Custom Research North America.

"Brazil is associated with all these qualities of good humor and good living and Carnaval," says Anholt. "Carnaval is very important--it's the classic image that people have of Rio, and it's an image of happiness.
Behind the Numbers
The data Anholt provided for our list is part of the 2009 Anholt-GfK Roper City Brands Index, released in June. The research was compiled through online interviews with 10,000 respondents in 20 countries.
Happiness is difficult to quantify, and Anholt acknowledges that his data is less an indicator of where local populations are happiest than a reflection of respondents' thinking about where they could imagine themselves happy.
"This is a survey of perception, not a survey of reality," he says. "People write me all the time and say 'that's not true.' It probably isn't true, but it's what people think. The gap between perception and reality is what interests city governments."
The French historian Fernand Braudel wrote that " Happiness, whether in business or private life, leaves very little trace in history." But a perception of happiness leaves a strong trace on the balance sheets of cities that depend on conventions, tourism and an influx of talent.
