Despacito YouTube viewsFurniture and TV tip-over ER injuries
Between 2017 and 2022, as 'Despacito' accumulated views on YouTube from 3 billion toward 8 billion, furniture and TV tip-over injuries presenting to US emergency rooms declined. The negative correlation of -0.97 is striking. One hypothesis is that the song's hypnotic qualities kept people safely seated. Another is that as children aged past the toddler years โ when tip-over injuries peak โ they discovered YouTube, began watching music videos, and in doing so accidentally became safer. The data does not say which. The data just gestures meaningfully.
YouTube viewership in general surged in 2020 as locked-down households turned to screens for everything โ viral music videos included โ while furniture tip-over injuries rose as families spent unprecedented time at home with children and new WFH furniture. The same housebound year drove both the stream and the stumble.
A genuine public health improvement and a streaming milestone can share a trendline without sharing a cause. This is worth remembering the next time a dataset appears to vindicate an intervention that nobody actually implemented.
