A State-by-State Analysis of Income Trends
Inequality has been increasing in Oregon for nearly two decades. This can be observed by ranking all Oregon families with children according to their income level, dividing them into five groups (or fifths) of equal size, and calculating the average income of each fifth of families. This analysis shows by the mid-1990s:
The Long-Term Trend
Since the late 1970s, income inequality has increased in Oregon. The long-term economic growth of the past two decades was not shared evenly among the poor, the rich, and the middle class. Instead, the top fifth of families with children fared substantially better than other income groups.
The gap between the top fifth of families and the bottom fifth of families grew by 46 percent since the 1970s.
The Recent Trend
Over the past decade, income inequality has increased in Oregon. While the average incomes of poor and middle income families with children have fallen since the mid-1980s, the average income of the richest fifth of families has stayed approximately level.
The gap between the top fifth of families and the bottom fifth of families increased between the mid-1980s and the mid-1990s faster than in all but 15 states. The gap between the rich and the middle class also rose.
