Just in case you need some more proof, Politifact looked it over and rated it False.
From the article linked:
It was not clear from the released results how the companies came up with the 400 percent jump. The percentage of African-American respondents who owned businesses was not published, nor was that figure from last year.
The survey sample was not random, the response was voluntary, and the margin of error was not made public.
This graphic said it relied on the same survey data, and it highlighted the African-American business owners in the pool. The methodology the companies provided did not break down respondents by race, only saying that minorities accounted for 47 percent of aspiring entrepreneurs who responded.
PolitiFact contacted Guidant about the claim in the graphic on Aug. 21. Two days later, a new version of the graphic was posted, this time without any mention of a 400 percent increase.
“We have found that the 400% statistic is being misrepresented in its context and therefore we have decided to pull that statistic from our info graph,” public relations consultant for Guidant Stacia Kirby said in an email. “Our mission is to help people get started and funded in owning their own business.”
When it comes to black-owned business numbers, we couldn’t find another source that supports this increase from 2017 to 2018. The Annual Business Survey data about Business Owner Characteristics for 2017 is not yet available, and most recent census data related to minority-owned businesses is from 2016.
Robert Fairlie, an economics professor at the University of California-Santa Cruz, studies entrepreneurship and authored a book about its relationship with race in the United States.
Fairlie said there was no indication that African-American businesses had seen significant growth in the past year.
“That would be great if there was a 400 percent increase given that African-American rates are so low, but everything that I have seen from Census and BLS data does not show that kind of growth,” Fairlie said.
Its simply a viral lie that is making the rounds, and enough Trump supporters are biting to keep it alive. Desperate times I suppose.
