Costco's annual revenue rising as American belief in God declines. Two completely unrelated trends on opposite sides of the regression line: one bulk-discount retailer scaling its membership, one slow secular shift away from organised faith.
Costco annual revenue grew from about 88 billion dollars in 2011 to over 240 billion by 2023 as the warehouse-club business expanded internationally and the Kirkland private-label gained share. American belief in God has trended down over the past decade, with Gallup polling showing belief fall from about 92 percent in 2011 to roughly 81 percent by 2023. Two completely unrelated lines on opposite trajectories sharing a window because the same twelve years rewarded one retail format and saw a long-running secular shift.
Two completely unrelated American trends moved in opposite directions. The membership and the belief, allocated differently.
