How many civilian deaths were there during world war ll? how many homeless/refugees?

deaths:

Some 75 million people died in World War II, including about 20 million military personnel and 40 million civilians, many of whom died because of deliberate genocide, massacres, mass-bombings, disease, and starvation.

homeless/refugee:

Many more people than that — 70.8 million — have been forcibly displaced from their homes. The previous spike in displacement occurred after World War II when 60 million people were left homeless.

Explanation:

Third Person Objective—the narrator is not part of the story and does not know characters’ thoughts or a feeling, but only states their actions and speech. Imagine you are holding a video camera. You see all the action, but there is no one to tell you what the actors are thinking.

Hope this helps :)
