the income vector |
k |

Richness headcount ratio is a proportion of the population with incomes above the affluence line
R^{HC}(\mathbf{x},ρ)=\frac{1}{n} ∑_{i=1}^{n} \mathbf{1}_{x_{i} > ρ} = \frac{r}{n},
where x_i is an income of individual i, n is the number of individuals, ρ is the richness line, r is the number of rich.
