Household income is a skewed bell curve [0]. Some graphs make it it appear bi-modal because the last few bars will contain larger buckets: in this chart, the last 2 bars represent $50,000 in values where all proceeding values are $5,000 [1]. When looking at the change over time, there is an increasing number of households at the upper end of the curve [2].
