These are the 10 wealthiest cities in the world—3 of them are in the U.S.

In April, Henley & Partners released its annual report on the world's wealthiest cities. The report's findings are based on just how fast the millionaire population has grown in the past 10 years in major cities across the globe.

New World Wealth, a global intelligence firm, collected data from 97 cities across nine regions worldwide. The report ranked the cities based on the spending habits of over 150,000 high-net-worth individuals, emphasizing those with over $10 million in investable assets.

It's important to note that Henley & Partners' report primarily focused on wealthy individuals who have titles at work that include founder, chairperson, CEO, and director.

All data used to create the report was collected on December 31, 2022.

New York City came in at no. 1 on the list. The report found that from 2012 to 2022, the city had a 40% growth in its population of high-net-worth individuals.

According to Henley & Partner's report, NYC is home to 340,000 individuals worth over $1 million, 724 centi-millionaires, and 58 billionaires.

The Big Apple is home to the highest number of individual homeowners with an ultra-high net worth of over $30 million, according to a 2021 report from financial information and insight firm WealthX and real estate platform REALM.
