List of countries by wealth per adult  This is a list of countries of the world by wealth per adult, published annually in Credit Suisse's "Global Wealth Databook" a company based in Zürich, Switzerland. It includes both financial and non-financial assets. In the tables below mean and median wealth per adult are reported. Every autumn, Credit Suisse S.A. publishes its Global Wealth Report Databook. It reports various statistics relevant for calculating net wealth. These figures are influenced by real estate prices, equity market prices, exchange rates, liabilities, debts, adult percentage of the population, human resources, natural resources and capital and technological advancements, which may create new assets or render others worthless in the future. During periods of equity market growth, the relative national and per capita wealth of countries where people are more exposed to those markets, such as the United States and the United Kingdom, tends to rise. But when equity markets are depressed, the relative wealth of countries where people invest more in real estate or bonds, such as France and Italy, tends to rise instead. Countries with older populations, like Germany and Italy, would have higher relative wealth, if calculated per capita and not per adult. There is a difference between median and mean wealth. Median wealth is the amount that divides the wealth distribution into two equal groups: half the adults have wealth above the median, and the other half below. Mean wealth is the amount obtained by dividing the total aggregate wealth by the number of adults. In nations where wealth is highly concentrated in a small percentage of people, the mean can be much higher than the median (e.g. the United States and Sweden).
