Chris Rock actually grew up mostly in the 1970s instead of the 1980s. But Rock felt that 70s culture has been parodied enough with shows like That '70s Show (1998) and moved the time period to the 80s.
Rock initially did not want to cast Tyler James Williams as Chris because he felt Williams was too good-looking to play a kid that everybody hates. But CBS executive Leslie Moonves (CBS owned UPN) insisted on Williams.
Chris Rock's real family had mom, dad, 6 other brother, 1 other sister, and himself. He said that using 6 brothers and 1 sister would've been weird, so he thought it'd be better to use some of his sibling's personalities to make 2 siblings for the show.
Jacqueline Mazarella's role of Ms. Morello was originally only supposed to be for one episode and she had only one line. ("Hello, Chris.") But during her audition, she was encouraged to improvise and "flirt" with Chris. She impressed the producers so much that her role was expanded in later episodes.
Tichina Arnold composed a theme song for the show and recorded it with 2 of her friends. However, Ali LeRoi and Chris Rock already had some themes in mind, so they kept the ending of it to put in at the end of episodes and before commercial breaks.

She played Sandra Clark in 227 (1985) (which show was also mentioned in the show) and Lisa Landry in Sister, Sister (1994).Jimmie Walker , who played Rochelle's father, was best known for playing JJ Evans on Good Times.

According to the season 1 DVD release of the show, the episode "Everybody Hates the Babysitter" on the disc has the cast commentary in the episode and said that Tichina Arnold ad-libbed a lot of the things she says in the show.
Tyler James Williams (Chris) & Tequan Richmond (Drew) were both born in October 1992 and were 12 at the time the show premiered. However, it was revealed that there was a two-year age difference between them on the show.
Tichina Arnold who plays Rochelle and Tisha Campbell who plays Peaches Clarkson in a few episodes both stared as best friends on the comedy show Martin.

Chris Rock's actual father, Julius Rock (the inspiration for the show's character) died from peptic ulcer disease in 1988, which is a year ahead from the time where this episode takes place in 1987.

In Everybody Hates G.E.D., the man that Chris stares at is said to be the owner of Red Lobster. Red Lobster was the first job Chris Rock said he had when he got his G.E.D. Chris references this when he asks his mother if Red Lobster is hiring.
