The paradox. Lower-income countries own far fewer vehicles per person, yet carry far higher road-death rates. The WHO Global Status Report attributes this gap to factors such as vulnerable road users (pedestrians, cyclists, motorcyclists), mixed traffic, vehicle and road conditions, and post-crash emergency care — interpretive framing, not a World Bank ranking.

World Bank aggregate series. Income groups (high / upper-middle / lower-middle / low) and regions are the Bank's own classifications. The spark line traces 2000→latest; "change" is latest vs. 2000. These aggregates are population-weighted estimates, not a simple average of member countries.
