The bar graph compares the quantity of households in the US according to how much the citizens earn per year in 2007, 2011, and 2015.
Overall, most of the citizens of all income levels owned more houses over time, whereas those who earned around $50,000 to below $75,000 had the same amount of households during the period. Additionally, that of income from $100,000 and above is the highest figure for most of the period while the lowest is seen with income from $75,000 to below $100,000.
Individuals that earned from $25,000 to below $50,000 and below $25,000 both saw an increase in the amount of households to a peak of almost 30 million and around 28 million respectively in 2011, making that of income from $25,000 to below $50,0000 the highest figure at that time. Four years onwards, the figures slightly dropped by approximately 1 million. Meanwhile, that of income from $50,000 to below $75,000 remained at the same level with the starting point, standing at just above 20 million.
Despite the opposite rankings in numbers of households, income from $75,000 to below $100,000 and from 100,000 and above shared the same pattern during the examined period. In 2007, their figures were approximately 15 million and 30 million respectively. Then they both plummeted in 2011 to around 14 million and 27 million respectively before a sharp rise in 2015. This had made the number of households of income from $100,000 lag behind that of income below $25,000 and income from $25,000 to below $50,000 in 2011. However, citizens who made from $100,000 and above owned the most houses in the US in 2015, at around 33 million.
