Americans with means are on the move. Coldwell Banker's just-released luxury homes report shows a 23% increase from 2002 in $1 million-plus home sales last year -- an all-time high for the real estate company. The average sales price of a luxury home sold by Coldwell associates was $1.69 million. The average number of bathrooms was not disclosed.

All told, the company moved $23.3 billion in property last year -- nearly 14,000 McMansions changing hands. The biggest movers were homes in the $1 million to $5 million price range. Alex Perriello, Coldwell's president and CEO, said he expects demand for luxe digs to remain high. "We expect activity to remain strong in the luxury category with a rebounding economy, continued low interest rates, and strong demographic trends that will keep demand high."

Really, what the rest of us want to know is where these gilded palaces are located. Not surprisingly, California dominates the luxury-home category with six times more sales ($12.6 billion) than any other state. Florida ranks second with more than $2 billion in big-home sales.

The rep who sold the $22.6 million home in Malibu must be smiling. That was the top price paid for a Coldwell listing. A Montecito, Ca., mansion sold for $21.6 million, and a home in Greenwich, Ct., went for $15.5 million.
