Recent data from Trulia reveals that the number of homes worth at least million dollars doubled in the past four years. Some places have a veritable monopoly on ritzy domiciles.

"Over the past four years, the number of million-dollar homes in the US has doubled," according to article by Alice Truong, who reports the news with data produced by Trulia. (The Trulia data is explained in detail in an original post by Ralph McLaughlin.)
The real stars of this article's show, however, are the cities, towns, villages, and census-designated places with 100 percent of their housing stocking topping the million-dollar mark. Small cities, towns, villages, and census-designated places in Hawaii, California, Florida, New York, Wyoming, and Washington make up the list.
A separate article by Patrick Clark provides a deeper analysis of the large cities with the highest portion of million-dollar homes (with San Francisco leading the list).
