US GDP per capitaUS comic book and graphic novel market
Between 2002 and 2022, the US comic book market grew and US GDP per capita grew, and the two curves have risen together (r = 0.957) with the unhurried grace of two industries that understand each other. Superheroes became more expensive to print; Americans became more expensive to employ; the graphic novel became a respectable thing for an adult to read on a plane. Everyone adjusted to the new prices.
US comic book and graphic novel sales grew from about $360 million in 2002 to over $1.4 billion by 2022, led by manga's explosive growth post-2020, the Marvel/DC film halo, and the mainstreaming of graphic novels through Barnes & Noble and Amazon; US GDP per capita grew from about $40,000 to over $76,000 in the same window. The specific overlap is manga: Japanese graphic literature accounted for more than 40% of the US comic market by 2022, a dramatic shift from the 5% share at the start of the window, and it rode the same global streaming/anime wave that delivered higher-margin consumer categories to slightly wealthier American shelves.
A comic is purchased. A paycheck arrives, slightly larger. Both grew with the decade; both are heavier than they used to be.
