If you're hunting for the fastest-growing companies, you'd do well to look at the Western states, since, after all, that's where most of them started. A breakdown of metro areas shows most of this year's Inc. 5000 companies are based in California metros such as Los Angeles (274), San Francisco (164), and San Diego (113). 

There is one surprise, however, and it's that New York--or Silicon Alley--has the highest concentration of Inc. 5000 companies in the U.S. That's right, 399 of these small businesses call the Big Apple their home, almost as many as Los Angeles and San Francisco's companies combined. 

Perhaps that's because so many of these companies are Web-based and operating in media, advertising, and financial services, all sectors that tend to concentrate in New York. Or perhaps it's because New York City's tech sector has ramped up hiring in a big way (though Silicon Alley still has a long way to go before it becomes the next Silicon Valley).

The graphic below shows the number of Inc. 5000 companies in the top 25 metro areas. For a full list of companies, click on the city's name beneath the map.
