The lucky number of individuals worth $30 million or more is expected to grow by 33% over the next five years — and they all need homes. 

A new report narrowed down where the moneyed are living, where they’re buying second homes and where they’re rubbing elbows. The data, compiled by the information services firm Altrata and reported by Mansion Global, geographically tracked the real estate moves of individuals with net worths exceeding $30 million. 

In the industry, these filthy-rich buyers are referred to as “ultra-high-net-worth individuals,” and their residential footprint is growing internationally. Members of this affluent demographic own an average of three homes, according to the report.

“Today’s affluent think in currencies, not countries,” said Julie Faupel, ceo of the invite-only realtor community Realm, which sponsored the report. 

If the richest of the rich did think in countries, however, the United States would be top of mind. A grand total of 15 US cities appeared on the report’s ranking of global metros with the most ultra-wealthy buyers. Only two European cities, Paris and London, made an appearance in the top 20. 

New York City, in particular, continues to reign supreme among the global well-to-do. Big Apple homes are owned — but perhaps not occupied — by more than 33,000 ultra-high-net-worth individuals, according to the data. 

The reputation of wealthy NYC buyers snapping up penthouses without regard for economic uncertainty and political shifts could be waning, however.

Jeremy Stein of Sotheby’s International Realty — which published a mid-year luxury market outlook in June — told The Post that the city’s ultra-luxury segment is no longer reaching the same heights it did in 2024. It continues to outperform the broader market, however.

The luxury co-op market, which struggles to compete with turnkey condos, is seeing a notable bounce back as sellers concede to more realistic pricing, Stein added.

Ranking runner-ups Los Angeles and Hong Kong lagged behind New York with populations of upper-crust owners numbering close to 20,000 each.

Miami, a recent rankings climber, overtook New York as the most popular metro for luxury second homes. Miami beat out other hot spots like London, Beijing and Hong Kong with with 13,200 über-wealthy second-homeowners. Prosperity in the Sunshine State didn’t stop there — the relatively small metro of Naples notched an extreme ratio of 19 ultra-rich second-home owners for every one primary resident.

Aspen, Colorado ranked third for the highest concentration of ultra-wealthy owners. One in every 77 residents of the snowy city is worth more than $30 million, according to the report. The crème de la crème are packed in like sardines in Monaco, which leads the density rankings with one in 22 residents classified as ultra-wealthy.
