2015-16: The highest 20% of household wealth groups holds 62% of all wealth. The middle 20% wealth group holds 12%, and the lowest 20% wealth group holds less than 1%. Wealth is highly concentrated at the very top. The highest 10% wealth group owns 45% of all wealth while the highest 5% owns 32% and the very highest 1% holds 15%. So the share of the highest 1% (15%) is greater than the middle 20% (12%). This probably underestimates of the true extent of wealth inequality. The wealthiest 1%, who own a disproportionate share of all wealth, are a small number of people and so are underrepresented in household surveys. It is also likely that many under-report their wealth. In contrast, the combined wealth of the lowest 40% is just 6% of the total.   2017-18: The highest 20% of household wealth groups holds 61% of all wealth.
