TIL there are more NPCs in Morrowind than in Oblivion and Skyrim combined

Morrowind - 2675 NPC Tribunal - 125 NPC Bloodmoon - 114 NPC Oblivion - 855 NPC Shivering Isles - 91 NPC Skyrim - 1016 NPC Dragonborn - 88 NPC

And something even more baffling. Amount of Imperials. In Morrowind + Tribunal + Bloodmoon there is 237 Imperial NPC, while in Oblivion + SI there is 219 Imperial NPC.
