Keep in mind that that's only one death. The number of people who die in Harry Potter would pale in comparison to the number of deaths in Animorphs.
17000 yeerks, countless humans, andalites, taxxons, hork bajir, planets, galaxies and solar systems in the ellimist chronicles. Harry potter's death toll, even if you count the nameless and faceless people whom Voldemort presumably had killed in the First War tallied up would account to slightly less than a single continent's population.
