A new study has found that money CAN buy happiness. The study, which was recently published in the Journal ‘Emotion,’ says that for people age 30 and older, the correlation between income and happiness has steadily risen over the years.

The study used data from the General Social Survey (GSS), one of the longest-running nationally representative surveys of U.S. adults, with 44,198 participants between 1972 and 2016.

So how much does it take? Adults who made more than $108,000 were 5% more likely to be “very happy.”

The study says that the decrease in happiness among lower-income people may be a result of rising inequality, skyrocketing real estate values, and decreased ability to pay for education.
