Now, let's determine the quality of each split by weighting the impurity of each branch. Birthday - 18 November 1989. Changing income inequality, measured by Gini coefficients, can be due to structural changes in a society such as growing population (increased birth rates, aging populations, increased divorce rates, extended family households splitting into nuclear families, emigration, immigration) and income mobility.

Suppose all people have non-negative income (or wealth, as the case may be).

Then, the first child node's Gini impurity is 1 - (1/2) 2 - (1/2) 2 = 0.5, which is higher than its parent's. This is compensated for by the fact that the other node is pure, so its overall weighted Gini impurity is 2/5 0.5 + 3/5 0 = 0.2, which is lower than the parent's Gini impurity. Publisher.
