Richness headcount ratio is a proportion of the population with incomes above the affluence line. Weighted version (with weights w_1,w_2,...,w_n) of this ratio is given by:
R^{HC}(\boldsymbol{x},\boldsymbol{w},ρ_w) = \frac{∑_{i=1}^n \boldsymbol{1}_{x_i > ρ_w}w_i}{∑_{i=1}^n{w_i}},
where x_i is an income of individual i, n is the number of individuals, ρ_w is the richness line,\boldsymbol{1}_{(\cdot)} denotes the indicator function, which is equal to 1 when its argument is true and 0 otherwise.
