The Bozo Index is an attempt to compare "Is West Chester doing better at wearing masks than Media? That Downingtown? Than Coatesville?"
"I'd love a smoothie. Should I get curbside pickup from Jaco?" "Better wait until tomorrow, the Bozo Index in West Chester on Saturdays is crazy."
(Please improve on me!)
This is used to calculate the bozo index for a particular street at a particular time.
