billionaire

A billionaire, in countries that use the short scale number naming system, is a person with a net worth of at least one billion (1,000,000,000, i.e. a thousand million) units of a given currency, usually major currencies such as the United States dollar, the euro or the pound sterling. Additionally, a centibillionaire (or centi-billionaire) has been deemed applicable to a billionaire worth one hundred billion dollars (100,000,000,000), a mark first achieved in 2017 by Amazon founder Jeff Bezos, with a net worth of $112 billion in a report issued in early 2018. The American business magazine Forbes produces a global list of known U.S. dollar billionaires every year and updates an Internet version of this list in real time. The American oil magnate John D. Rockefeller became the world's first confirmed U.S. dollar billionaire in 1916, and still holds the title of history's wealthiest individual.As of 2018, there are over 2,200 U.S. dollar billionaires worldwide, with a combined wealth of over US$9.1 trillion, up from US$7.67 trillion in 2017. According to a 2017 Oxfam report, the top eight richest billionaires own as much combined wealth as "half the human race".
