St. Brutus's secure center for incurably criminal boys
The Dursleys were the closest in relation to harry potter after his parents died
No, none of the Dursleys die.
There is the mortal world, where the Dursleys live, and the Wizarding World, which Harry attends school at. Hope that helps! :D
It's actually Harry, because Dudley is their son and Harry is the son of Petunia's sister, Lily, so he is Petunia's nephew.
He was taken there on Dumbledore's instructions, after his parents died. The Dursleys were Harry's only living relatives.

In the Dursleys house.
The Dursleys
The Dursleys leave for their own protection, because when Harry turns 17 the protective charm at their home will break, even if Harry is gone it is likely that the Death Eaters will capture and torture them for information on Harry, as they would neither be particularly aware of, or care about, Harry's lack of a communicative relationship with the Dursleys.
With The Dursleys
He was taken there, on Dumbledore's instructions, by Hagrid.
The Dursleys did not treat Harry as their own son because they hated that he was a wizard, Vernon because he was a bigot Petunia because she was jealous, and Dudley because he was raised to treat Harry badly.
