As Baby Shark has accumulated billions of YouTube views, frozen pizza sales have grown, a correlation of 0.987 across seven data points that captures the essential parenting experience of the late 2010s: a toddler watching Baby Shark on repeat while the exhausted parent heats up a DiGiorno in the kitchen. The song loops, the pizza bakes, and the chart records both with the frazzled precision of a correlation that has been up since 5 AM.
Baby Shark accumulated over 13 billion views between 2016 and 2022, becoming the most-watched video in YouTube history. Frozen pizza sales grew from about 5.5 billion to over 7 billion during the same period, boosted by the pandemic's push toward home eating. Both trends serve the same household: parents with young children who consume both children's content and convenient food. The pandemic accelerated both—more screen time for kids and more frozen meals for families. The shared variable is the modern parenting experience: exhausting, screen-mediated, and adequately fed.
Seven years of Baby Shark and frozen pizza is the most honest parenting correlation on this site: the same household watching the same video and eating the same dinner, measured from the living room and the kitchen. The song plays, the timer dings, and the correlation is simply the life cycle of a family with a toddler and a freezer. Doo doo doo doo doo doo. Ding.
