The Gini coefficent is named after Italian statistician Corrado Gini.
0 represents perfect equality and 1 represents perfect inequality.
A country in which every resident has the same income would have an income Gini coefficient of 0. Conversely, a country in which one resident had all the income, while everyone else had nothing, would have an incomeGini coefficient of 1.
The same analysis can apply to wealth distribution but wealth is more difficult to measure than income. Wealth Gini coefficients tend to be much higher than those for income. The imbalance in the UK is driven by regional differences in property wealth.
In the Equality Trust graphs for 2018-2020 we can see the median wealth for the south east of England is around three times higher than for the north east of England
Hence the Gini coefficent for income is 0.351 while the wealth coefficient is 0.746 which represents an average for the UK as a whole.
