Spokane, King County and Washington inflation adjusted household median income charts

A reader who also needs to be anonymous, has provided an additional chart comparing Spokane County, King County and the state of Washington household median incomes, adjusted for inflation. The results are similar to those posted last week, but these show Washington and King County falling backwards in income over the period 1992-2009.

The lines to compare in this chart are purple to green to red:

The above charts are for the period 1992-2009, while the chart I provided last week is for the period 1989-2010.

For the period 1992 to 2009, all areas show declines in median income.

Differences between this chart and my Spokane County median income chart may be due to differing reporting periods, different data sources (see “After the break”, below) and CPI adjustments. Between 1989 to 1992, Spokane County after inflation adjusted median income rose by 1.4%. From 2009 to 2010, Spokane County median incomes fell an additional 2.75%, which is not reflected in the above chart ending in 2009.

The main takeaway is that after inflation adjusted median incomes have not done well over two decades. The median income is the value at which half of incomes are less and half are greater. This is not the same as average income.

Data and more commentary for the above chart are after the break.
