Wealth is the total sum value of monetary assets and valuable material possessions owned by an individual, minus private debt, at a set point in time.
In nations where wealth is highly concentrated in a small percentage of people, the mean can be much higher than the median.
A Global Wealth Report is published annually by Credit Suisse.

For several European countries, Credit Suisse could only provide rough estimates of mean wealth, with no information about the distribution of said wealth, citing poor data quality.
