You can’t walk down the street these days without tripping over a millionaire

The Big Apple — call it the Golden Apple — and its suburbs are home to 667,200 millionaires, more than any region in the country.

That’s 18.7 percent more than two years ago. It’s even more than in 2007, the height of the economic boom, according to a new report by Capgemini, a consulting firm.

The richest New Yorker of all is Mayor Bloomberg.

He’s followed by David Koch, George Soros, John Paulson and Ron Perelman.
