Households in the two lowest income ranges had a similar pattern to each other. In 2007, there were about 25 million households that earned less than $25,000 per year, and a little more than that earned between $25,000 and $49,999. These figures rose by around 4 million by 2011 before dropping slightly by 2015.
The number of households with an annual income of $100,000 or more witnessed a big jump, rising from less than 30 million households in 2007 to roughly 34 million in 2015, despite a small drop in 2011 when it was outnumbered by the two lowest income groups. The numbers of households earning from $50,000 to $74,999 and from $75,000 to $99,999 remained almost the same over the period given, at a little above 20 million and approximately 15 million, respectively.
