A millionaire (originally and sometimes still millionnaire) is an individual whose net worth or wealth exceeds one million units of currency. It can also be a person who owns one million units of currency in a bank account or savings account. Depending on the currency, a certain level of prestige is associated with being a millionaire, which makes that amount of wealth a goal for some, and almost unattainable for others.
The increasing number of millionaires is partially due to prevailing economics: Increasingly, the term denotes more and more to the status of high wealth. American sociologist Leonard Beeghley classifies all households with net worth exceeding $1 million as "The Rich." Currently, there are over 10 million residents around the globe classified as millionaires.
The increasing prevalence of people with more and more money has given rise to additional terms to further differentiate millionaires. A multimillionaire has a net worth of more than 2 million units of currency, a decamillionaire has a net worth of more than 10 million units of currency, and a hectomillionaire has a net worth of more than 100 million units of currency. The term centimillionaire has become synonymous with hectomillionaire in America, despite the centi- prefix meaning 1/100, not 100, in the metric system.
While statistics regarding financial assets and net worth are presented by household, the term is also often used to describe only the individual who has amassed the assets as millionaire. That is, even though the term statistically refers only to households, common usage is often in reference only to an individual.
In the real estate bubble up to 2007, average house prices in some regions such as Palo Alto, exceeded $1 million. For this reason there are many people in million-dollar homes whose net worth is far short of a million—in some cases the net worth is actually negative. For this reason, those who market goods, services, and investments to high net worth individuals are careful to specify a net worth "not counting principal residence."
While millionaires constitute only a small percentage of the population, they hold substantial control over economic resources with the most powerful and prominent individuals usually ranking among them. Forbes and Fortune magazines maintain lists of people based on their net worth and are generally considered authorities on the subject. According to Forbes
Depending on how we calculate it, a million US dollars in 1900 is equivalent to 2006 US dollars of
Thus we see that at the turn of the 20th century one would have needed twenty to a couple of hundred times more modern US dollars than one does today, to qualify as a millionaire (in the US).
Roughly 1.0% of high net worth individuals (HNWIs) can also correctly be identified as ultra-high-net-worth individuals (ultra-HNWIs), those who reside in households with a net worth or wealth of $30 million or more. There are approximately 95,000 ultra-HNWIs in the world with 61,600 or 64.8% residing in the United States and Europe.
World Wealth Report 2007 - "The 11th annual World Wealth Report from Merrill Lynch/Capgemini finds the World’s High Net Worth (HNW) population growing to 9.5 million with their assets rising to $37.2 trillion."
Some growth in international wealth and the number of high net worth individuals can be attributed to the weakness of the US dollar, as stated in the report.
