2008 Portland Metro Income Distribution


The red line shows the share of income held by each centile (1%) of population. A perfectly egalitarian distribution would follow the 45 degree blue line from the lower left corner to the upper right corner.

Any real world distibution would fall short. The question is how much. The Gini coefficient measures the amount of area between perfect equality (the 45 degree blue line) and the actual distribution of income along the red line.

The Gini coefficient for the Portland Metro Area in 2008 equalled 0.45.

The Portland Metro, as defined here, includes Clackamas, Multnomah, and Washington counties.
