income

categories: less than $25,000, $25,000–$49,999, $50,000–$74,999, $75,000–$99,999, and $100,000 or more in the

years

2007, 2011, and 2015.

Overall

, the data indicates that

households

earning $100,000 or more experienced a consistent increase,

while

years

. In 2007,

million

, but

this

years
