Lorenz Curve and Income Inequality

Thank you most informative

First, the volume of this video is so low all I can hear is a low hum.

Second, all this math is going to be lost of people who have not

had some advanced math and statistics, like integral calculus and

series.

The area of the curve bounded by the diagonal line/triangle can be almost any shape as well ... so I am not getting what you are saying.

You could do better if you showed what you are thinking would be ideal. I just think this is a poor video.

@jei69 did you mean .17/.5? i had trouble with this too. the area under the 45% line is always .5. the area of the green, is .17. dividing by .5 is the same as multiplying by 2.  to get the .17, i subtracted the area under the lorenze curve from .5 since i calculated this area with rectangles and right triangles. hope this helps...

@jei69 hi...i drew a right triangle knowing that i was approximating the slope of the lorenz curve. it isn't perfect, but it's a good approximation...i add this area to the area of the rectangle...does this help?

Thank youu!!!!!!!!!!!!

Thank you! That helped a lot, but I think the only thing I didnt understand is for Gini-Coefficient, where does the .5 come from? I know you said from the right triangle, but Im still kind of confused.

[fladdog]

The Gini Coefficient is actually the ratio of the area under the Lorenz Curve to the area of the right triangle.  The area of the right triangle would be .5. Dividing by .5 is the same as multiplying by 2.

Ohh! Okay! Thanks!
