DALLAS (STACKER) — You can’t go through an election season without hearing the phrase “small businesses are the backbone of America” repeated over and over again. But while the adage may feel tired, it is far from untrue. Small businesses account for a whopping 99.9% of companies in the U.S., according to the U.S. Small Business Administration (SBA). The number can be partly attributed to the administration’s broad definition of a small business as any firm with fewer than 500 employees, but it also reflects how embedded entrepreneurship is in American culture. We watch in awe as once-small startups, like Twitter and Slack, transition into hugely successful ventures that are part of our everyday lives. We binge-watch old episodes of “Shark Tank,” eager for inspiration for the next great business idea. And many of us dream of starting our own companies by dipping our toes into entrepreneurship with side hustles.

But as dreamy as business ownership can seem, it takes a lot of grit, hard work, and old-fashioned luck to find success. Recent data shows that fewer than 80% of businesses make it beyond their first year, while only around half survive for at least five years or more. Small businesses also provide employment for nearly 60 million workers, and the pressure of making payroll every week can be crippling if sales don’t meet expectations. Understanding the good, the bad, and the ugly about entrepreneurship is the only way you can decide if it’s the right career path for you.

To learn the truth about small businesses in America, Stacker took a look at figures and facts on entrepreneurship from a variety of sources, including the SBA, The Ewing Marion Kauffman Foundation, the Census, the Bureau of Labor Statistics, and news reports. The statistics painted a fascinating picture of who’s most likely to launch a business, the chances of a business to stick around for generations, and how much economic activity comes from firms that aren’t major corporations.
