How many pizzas are sold in the United States each day?

How to get close to this number

Decompose by outlet. The explanation gives around seventy-five thousand pizzerias, and a pizzeria sells a few dozen pizzas on an ordinary day. Outlets times daily sales gives a figure in the millions, and outlet-times-throughput is the standard method for any national retail volume question.

The weekly pattern matters more than the average: Friday is the biggest ordinary day and one Sunday in February is the biggest of the year. Food demand is intensely periodic, and a daily average describes no actual day — capacity has to be built for the peak, which is why delivery times collapse on exactly the days everyone orders.

The topping statistic is the one that reveals how concentrated preferences are: one topping appears on more than a third of all pizzas ordered. For a food usually presented as infinitely customisable, actual orders cluster hard around a few defaults — the same concentration pattern as the Spotify listening question on this site.
