The name of the street refers to the hedges that enclose many suburban gardens, as Rowling liked the idea of enclosure. In the novels and films, the Dursleys' home is in a respectable and boring neighbourhood where the neighbours ostracise Harry, who despises Little Whinging because of his memories of his cruel treatment there. Arabella Figg, who lives two streets away from 4 Privet Drive in the novels (but just across the road in the films) knows of Harry's magic, because she is a Squib member of the Order of the Phoenix, placed in Little Whinging by Dumbledore to keep an eye on Harry. In "Harry Potter and the Order of the Phoenix", Dumbledore reveals that the reason Harry must return there at least once a year is because of the protection Harry's mother left upon him when she gave her life to save him. That act allowed an "ancient magic" to work, which meant Harry could never be harmed as long as he lived in the care of his mother's blood; in this case, his Aunt Petunia. This charm would not expire until Harry turned 17.
