The ONS recently released the third round of their "Wealth in Great Britain" survey. There is a lot of interesting information in this survey including the headline results below. The ONS have also included subjective well-being questions in this survey which will be of interest to researchers. There is still a lot to be learned about how precisely to ask these types of questions to respondents and more experimentation on the sensitivity of wealth estimates to question-wording would be a good development.
"In 2010/12, aggregate total wealth of all private households in Great Britain was £9.5 trillion.
The wealthiest 10% of households owned 44% of total aggregate household wealth.
Half of all households had total wealth of £218,400 or more."
