The statistics are based on Inheritance Tax returns and include information on the distribution of wealth, liquid wealth, the assets held by estates and how those vary by age and gender. They also include new statistics on property, interest and dividend income based on HMRC’s Survey of Personal Incomes and Self Assessment returns. More information on this can be found in the published commentary.
Identified wealth is the wealth represented by estates passing on death each year that require a grant of representation. Not all estates require a grant of representation and figures in these tables do not represent the entire population. The identified wealth population represents around 15.153 million people which is 30% of the average annual UK adult population over the period 2011 to 2013.
