I can't help but notice that the meme starts with white comedians noticing how often it occurs among their (presumably largely white) listeners, and KnowYourMeme is quite unconvinced that "the issue is so common with black Americans." It seems like a joke became a meme, which almost immediately became a stereotype, sped along by social media irresponsibility. There's not a shred of actual evidence there; and even to the extent the data might shake out to support the claim, there are way too many confounding variables for you to be saying stuff like this.
The background chirp of smoke alarms needing new batteries is a well understood phenomenon across the internet, but something I have never seen mentioned by the captured media, education, or government. This recognition of African American fire risk is the closest I have ever seen without being ripe with social justice style disclaimers
