As Statista's Anna Fleck highlights, this is a notable shift. Where in previous years the vows to exercise more, eat healthier and lose weight had come in top positions, now the financial goal has leapfrogged them to become the most commonly cited resolution this year.

This is according to data from a Statista's Consumer Insights survey.

Slightly further down the list came the goal of reducing stress from work and spending less time on social media (both 19 percent), while less popular resolutions included cutting down on alcohol (13 percent) and becoming a vegetarian or a vegan (3 percent).

In a similar vein to saving more money, one in four U.S. adults said they wanted to reduce their spendings on living expenses such as food and energy in the coming year.
