This map shows Neiman Marcus stores and the number of super-rich people who live nearby

Luxury department store Neiman Marcus filed to go public Tuesday. While the company (which also owns Bergdorf Goodman) has stores in 19 states, including Washington DC, wealth intelligence firm Wealth-X noticed a trend when it came to the retailer's preferred locations.

In 2013, the company mapped the distribution of ultra high net worth individuals in the US (defined as those with assets of $30 million or more) against locations of Neiman Marcus stores (not including 'Last Call' outlet locations).

The densest number of retail locations were in California, Florida, and New York, which together are home to more than 75% of Americans with over $30 million in assets.

"The emerging strategy for most retailers trying to capture the growing affluent market will be to use digital to drive retail traffic," Wealth-X President David S. Friedman said at the time. "For this segment, the physical retail experience will be critical for capturing the growth in the affluent market."
