A new study ranks San Diego 4th nationally in the number of startup businesses, ahead of Silicon Valley but behind Los Angeles, Austin and Miami.

The report by the Ewing Marion Kauffman Foundation ranked cities based on the percentage of the adult population starting new businesses each month.

For San Diego, that number was 0.49 percent — or about one out of every 200 adults.

“San Diego climbed seven spots year-over-year and now ranks 4th in the United States in startup activity,” according to 2017 Kauffman Index of Startup Activity. “Overall startup activity slightly increased in 2016, but slowed relative to the past three years of aggressive growth.”

One motivating factor in starting a business is being unemployed. The Kauffman Index found two out of every ten entrepreneurs in San Diego were previously unemployed.

Among states, California led in overall startup activity, followed by Texas and Florida.

The 50-year-old, Kansas City-based foundation promotes entrepreneurship in America.
