According to a 2014 study from researchers at the University of Scranton, just 45 percent of Americans admit to routinely making New Year's resolutions. The study also showed that an additional 38 percent of Americans acknowledged they never make New Year's resolutions. Among the former group, self improvement or education-related resolutions were most popular, followed by weight resolutions. The study also found that resolutions tend to be less successful as a person ages. While 39 percent of survey participants in their twenties reported achieving their resolutions each year, those in their fifties reported a success rate of just 14 percent. Time also seems to be against resolutions, as just 46 percent of respondents reported maintaining their resolutions for more than six months.
