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 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.

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.
