In The Kite Runner, what was the setting?

There are many settings in "The Kite Runner." The book opens in San Francisco's Golden Gate Park, in roughly the present. However, the book flashes back to Kabul, Afghanistan, where the narrator (Amir) grew up. The first chapters are mostly set there, in and around the luxurious house of his childhood. Later, when the family must flee the country, the story is set along the way, and then in Pakistan. They then move to the United States, specifically California, and much of the story is set there, as they try to make their home in a new land. Late in the book, there is a return to Afghanistan.
