The further the actual distribution of income is concentrated in the hands of the rich, the further the actual curve is from the 45 degree line. The dark line represents the initial distribution of income. Can you see that half the population only receives less than 30% of the total national income? (Hint : find 50 on the x axis, and find where this intersects with the darker Lorenz curve. Now move to your left until you reach the y axis.) In the example shown, the distribution of income has become more unequal over time. Analyse the new, lighter Lorenz curve. Now half the population only receives about 20% of the national income. This means of course, that the richest 50% of the population receive 80% of all the national income. The gap between the rich and the poor has clearly widened.
