10% of the population (the two poorest individuals) receives only 1.8% of the
total income, while the top 10% (the two richest individuals) receives 28.5%.
Finally, if we wanted to know what the top 5% receives, we would divide the
total population into 20 equal groups of individuals (in our example, this
would simply be each of the 20 individuals) and calculate the percentage of to
tal income received by the top group. In Table 5.1, we see that the top 5% of
the population (the twentieth individual) receives 15% of the income, a higher
share than the combined shares of the lowest 40%.
