It’s no secret that one’s rising wealth can lead to increased spending on goods, services and homes. And the number of those capable of spending more on a whole host of things has grown in the United States, which is worthy of note by institutional investors.

According to Capgemini’s recently released U.S. Wealth Report 2015, high-net-worth individuals in the United States increased their wealth by more than $1 trillion during 2014. The number of high-net-worth individuals — defined as those with more than $1 million in investable assets excluding primary residence, consumables and collectibles — expanded by 8.6 percent to 4.4 million people, and their actual wealth increased by 9.4 percent, or $15.2 billion. As a result, the United States maintains its status as the largest high-net-worth individual market globally.
