People who own a standalone GPS

American standalone GPS ownership going down as American broiler-chicken production goes up. Two completely unrelated stories on opposite sides of the regression line: a navigation-device category losing to the smartphone, a poultry industry replacing beef on per-capita protein.

Standalone GPS ownership has fallen steadily across this window as smartphone navigation absorbed the function. US broiler chicken production grew from about 36 to over 44 billion pounds in the same window as poultry continued displacing beef on per-capita protein. Two completely unrelated lines on opposite trajectories sharing a window because the same sixteen years saw one device category retire and one protein category expand.

Two completely independent trends crossed in the same window. The dashboard simplified; the dinner plate did not.
