To underscore the weak magnitude and geographic unevenness of new business formation, consider that the country as a whole contained only 52,800 more business establishments in 2016 than it did in 2007. Five counties alone surpassed that, with a combined 55,500 more businesses in 2016 than before the recession: Los Angeles, CA; Brooklyn, NY; Harris, TX (Houston); Queens, NY; and Miami-Dade, FL. Without those five counties, the U.S. would still contain fewer active business establishments than it had before the recession.
