The United States has a total area of 3,796,742 square miles. That makes it the third or fourth-largest country in the world by land area, depending if you count overseas territories. So what’s the point? Despite its size, the U.S. is facing a dilemma of sorts. According to a new report from The Brookings Institution, regional divergence in the U.S. innovation sector “has reached extreme levels.” The innovation sector, composed of 13 of the nation’s highest-tech, highest R&D industries, is vital to the U.S. economy. The innovation sector accounts for 3% of U.S. jobs, but generates 6% of the country’s GDP, a quarter of its exports and two-thirds of business R&D expenditures. The industries, such as software, pharmaceuticals and semiconductors, consist of workers with degrees such as science, technology, engineering and mathematics.

The report found that job gains in the innovation sector are becoming highly concentrated to a handful of “superstar” metropolitan areas. Boston, San Francisco, San Jose, Seattle and San Diego captured more than 90% of all new jobs in the innovation sector from 2005 to 2017. These cities’ share of the nation’s innovation sector employment increased from 17.6% to 22.8% during this period.

One-third of the nation’s innovation sector jobs are now in just 16 counties, with more than half concentrated in 41 counties. The hardest hit cities, in terms of losing innovation sector jobs over this period, include Chicago, Philadelphia, Dallas and Los Angeles.

The report discusses some of the negative externalities as a result of innovation sector jobs clustering to a few cities. The most obvious is housing. A separate report from PropertyShark found that California is home to 73% of the nation’s priciest zip codes. The Bay Area alone is home to 55 of the nation’s 125 most expensive zip codes….CLICK for complete article
