Electric vehicles registered in the USJapan total population
American EV registrations climbed between 2014 and 2023 while Japan's total population declined across the exact same years, and the two trends produced an almost perfect mirror image (r = -0.959). In California a Model 3 leaves the showroom; in Kyushu a maternity ward closes. These are not the same event. The graph insists they rhyme anyway.
US electric vehicle registrations grew from about 300,000 in 2014 to over 3.3 million by 2023, driven by Tesla's volume push, the IRA's consumer credits, and the emergence of plausible competition from Hyundai, Ford, and Rivian. Japan's population, meanwhile, fell from about 127.3 million to 124.3 million in the same window, with deaths outpacing births every year and immigration not quite filling the gap. The two trends are completely unrelated causally but share a decade in which American optimism about transportation replacement rose at roughly the same rate as Japanese demographic momentum declined — a wealthy country accelerating and a wealthy country aging, locked together by arithmetic.
A charger clicks on in Fresno. A schoolhouse empties in Akita. Neither knows about the other. The decade holds both.
