watch the leaded generation move through the country

a county time-map of the harms documented by the lead-cohort engine. press play and watch the front of the leaded cohort sweep through each outcome at the modal age. color is fixed across years, so motion is real change, not rescaling.

each metric has its own color ramp. exposure (child blood lead %) sits at the top of the rail, then core cohort fits sorted by signal strength, then sequestered series kept for honesty. ecological association at the birth cohort's modal age, not individual causation.
