Following four years of steady increases, the number of United States households in most wealth segments reached record highs, and all wealth segments saw large increases from 2012 to 2013. Mass Affluent Households, with a net worth between $100,000 and $1 million, Not Including Primary Residence (NIPR), grew to 28.97 million. This is an increase of 500,000 investors over 2012, and 3.77 million over the post-recession low of 25.2 million.
Millionaire Households with a net worth between $1 million and $5 million reached 8.39 million, an increase of 440,000 investors since 2012 and an increase of 2.53 million investors since the 2008 dip, when there were only 5.86 million Millionaires. The number of Millionaires has been slowly increasing since 2008.
The record-high stock market has played a large role in the return of Millionaires, as well as a return to previous numbers in other wealth segments as well.
The growth is similar in the Ultra High Net Worth segment. The number of households with a net worth between $5 million and $25 million reached 1.108 million in the U.S., an increase of 85,000 since 2012 and an increase of 352,000 since 2008.
Among the wealthiest Americans, there were 132,000 households with a net worth of $25 million or more in 2013, an increase of 15,000 from 2012, which was close to 10 percent. In 2008, there were only 84,000 investors with a net worth of $25 million or more, meaning there has been an increase of 48,000 since 2008.
