The top 50 richest Americans have surpassed the top 1,000 people in the United States for the first time in the history of Forbes magazine, according to the publication’s annual wealth report.

The top 50 people are worth an estimated $1.5 trillion.

They have more than tripled the $700 billion in wealth the Forbes 400 earned in 2014, the magazine said Wednesday.

That total includes the $1 trillion that has been accumulated by the top 0.1 percent of Americans, and includes the vast majority of the nation’s wealth held by the wealthiest 1 percent of the population, which Forbes said includes a small handful of families.

The new record comes after the Forbes 500 was named the world’s most valuable annual list for the fifth year in a row, in March.

The list was based on an annual valuation of all assets, assets held by individual companies, as well as a valuation of each of the 500 largest U.S. companies.

Forbes named the list based on its “value-added” model, which considers the value of each business as a percentage of its market value.

Its annual list, which was published on Wednesday, included information on the wealth of Americans from the Forbes 200.

The rankings were based on Forbes’ annual Wealth Report for the year ending Dec. 31, and were not adjusted for inflation.

“The wealth of the top 50 wealthiest Americans is the biggest it’s ever been, and that number is rising, even as income inequality continues to worsen,” Forbes said in a statement.

“It’s a testament to the strength of the U. S. economy and our country’s promise that the richest 1 percent is now worth $1,100,000 more than the bottom half of the country’s households.”

The report also included a look at the top 100 wealthiest Americans, which has risen from 10 in 2014 to 10 in the past five years.

The new top 100 include two family members: Stephen and Anne Adler, the heirs to the Adler fortune, which is worth more than $3.2 billion.

The Forbes 400 is the only list in the Forbes 250, a list of the 200 wealthiest Americans published by the investment firm BlackRock.

The other top 50, with Forbes ranking them 1 through 4, include the Adlers, Andrew and Catherine Adler of Washington, D.C., and the Walton family of Florida, whose fortune is estimated at $32 billion.
