US frozen pizza retail sales

It turns out that American consumers buying frozen pepperoni rectangles and Chinese consumers clicking 'buy now' on Singles Day—a shopping festival that celebrates being alone by spending money—move together across the globe with the synchronicity of conjoined twins who have never met. One might expect these two markets to operate in complete independence, separated by oceans and cultural logic, yet here they are, gliding up and down in perfect formation like a pair of economic dolphins who received the same mysterious signal. This says something rather bleak about humanity, or possibly just about spreadsheets.

What we're almost certainly watching is the broader hum of global economic confidence, that strange invisible force that makes everyone feel slightly richer or poorer at the same time. Between 2009 and 2021, the world was recovering from financial crisis, climbed toward prosperity, then got hit with a pandemic—and both frozen pizza sales and Alibaba's annual sales bonanza responded to these same economic weather patterns like barometers made of cheese and ambition. The sheer scale of Alibaba's Singles Day is worth grasping: by 2021, the company was processing $84 billion in transactions in a single 24-hour period, which is roughly the entire annual GDP of many nations, all while Americans were simultaneously buying approximately 350 million frozen pizzas per year. Both markets also benefited from the same underlying technology adoption and logistics improvements that made online shopping and frozen food delivery increasingly reliable.

We are all, it seems, passengers on the same economic bus, responding to identical invisible forces whether we're standing in a supermarket in Ohio or refreshing a shopping app in Shanghai. The correlation doesn't mean one causes the other—frozen pizza sales didn't make Singles Day bigger, nor vice versa—but rather that both are symptoms of something larger breathing in the background. When we find these patterns, we have discovered not truth but evidence of our connectedness, which is somehow both comforting and faintly embarrassing. Two datasets, one planet.
