^*Range based on estimates of excess pneumonia and influenza deaths (lower range number) and all-cause deaths (upper range number); estimated from projections of mortality surveillance from 122 cities.

^†Probabilistic estimates from the Centers for Disease Control and Prevention using 2009 pandemic survey data.³⁶

^‡Estimates based on the excess mortality approach applied to final national vital statistics and adjusted to year 2000 population-age structure.
