A millionaire is an individual whose net worth or wealth is equal to or exceeds one million units of currency. Depending on the currency, a certain level of prestige is associated with being a millionaire. Many national currencies have, or have had at various times, a low unit value, in many cases due to past inflation. It is obviously much easier and less significant to be a millionaire in those currencies, thus a millionaire in Hong Kong or Taiwan, for example, may be merely averagely wealthy, or perhaps less wealthy than average. A millionaire in Zimbabwe in 2007 could have been extremely poor. Because of this, the term 'millionaire' generally refers to those whose assets total at least one million units of a high-value currency, such as the United States dollar, euro, or pound sterling.
A billionaire is a person with a net worth of at least one billion units of a given currency, usually of a major currency such as the United States dollar, euro, or pound sterling. It is a sub-category of the concept of the ultra high-net-worth individual. 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.
The Forbes 400 or 400 Richest Americans is a list published by Forbes magazine of the wealthiest 400 American citizens who own assets in the U.S., ranked by net worth. The 400 was started by Malcolm Forbes in 1982 and the list is published annually around September. Peter W. Bernstein and Annalyn Swan describe the Forbes 400 as capturing "a period of extraordinary individual and entrepreneurial energy, a time unlike the extended postwar years, from 1945 to 1982, when American society emphasized the power of corporations." Bernstein and Swan also describe it as representing "a powerful argument – and sometimes a dream – about the social value of wealth in contemporary America."
