They are unpopular among millennials.
Consumer analytics provider Connexity says both brands are failing to win over the 18 to 24 demographic, despite new strategies designed to appeal to a younger, more health-conscious crowd, Adweek reports.
Coke ko is most popular among people aged 35 to 44, while Pepsi’s largest audience pep is those 65 and over. Both companies have attempted to expand their product lines and change serving sizes to suit younger consumers, but it doesn’t appear to have worked.
Connexity content director Rochelle Bailis told the website the two soda giants were “in this arms race to get the attention of millennial consumers. I don’t think either of them are doing it perfectly yet.”

Their mutual inability to bring in younger customers is one of the few things Coca-Cola and Pepsi have in common in terms of who’s buying. According to Connexity’s data, Pepsi performed well among people who lean slightly to the political left, while many Coke drinkers were more conservative, according to Adweek.
Coke drinkers are generally more likely to have a college degree than Pepsi drinkers, who are also reportedly far more likely to be low-income. Connexity’s research indicates that Pepsi drinkers are about 28% more likely than the average person to make less than $20,000 a year—Coke drinkers were found to be about 20% less likely to land it that income bracket.
