New York City’s government has spent years pushing the city as a rival to Silicon Valley. To a large extent, those efforts have succeeded: major tech firms, startups, and entrepreneurs call the five boroughs home. According to a new analysis from the Center for an Urban Future, the number of New York City residents working in the tech sector has increased 71 percent over the past decade. In an utterly unsurprising twist for a city where publishing constitutes another major industry, employment in the Internet publishing & broadcasting and Web search portals categories jumped 516 percent during that period, followed by e-commerce (188 percent increase), software publishing (93 percent increase), and computer systems design (67 percent increase). Breaking things down by borough, Manhattan hosts 83 percent of all tech sector jobs, followed by Brooklyn (9 percent), Queens (6 percent), the Bronx (1 percent), and Staten Island (1 percent). However, Brooklyn has enjoyed faster growth in tech jobs than any of the other boroughs. As with tech industries in other cities around the country, Silicon Alley remains majorly white (62 percent of all tech employees) and male (60 percent). Unlike some of its metropolitan rivals, the city attracts a pretty even distribution of ages (56 percent of tech workers are 35 and over), with older workers proving the majority in every sector except e-commerce and Internet publishing. Despite sizable investments in its tech community—including an e-hub for startups, Digital.NYC—New York continues to face competition for tech talent from not only Silicon Valley, but also up-and-coming cities such as Raleigh, N.C., all of which have made attracting big firms and startups a priority. But for the moment, there are significant signs that Silicon Alley is succeeding.
