Dive Insight:

With Generation Z contributing about $830 billion to U.S. retail sales each year, Piper Jaffray's findings illustrate how this cohort, more so than older generations, enjoys interacting with brands on social media and lets brands drive their purchases.The findings can help marketers craft campaigns to reach these young consumers and build brand loyalty, and underscore why marketers shouldn't lump Gen Z into the same category as millennials.

Instagram and Snapchat have been fierce competitors for Gen Z audiences, and the platforms have recently unveiled some new features aimed at attracting brands and new followers. Instagram expanded its Shopping tool and unveiled Shoppable Instagram Stories. Snapchat expanded its e-commerce offerings, as well, by allowing shopping within Snapchat Stories.

The Stories format has been a main driver of Instagram's growth. In 2018, 104.7 million people in the U.S. — 31.8% of the population — will use Instagram, a 13.1% increase from last year, according to eMarketer. The growth will mark the first time more than half of U.S. social network users will access Instagram at least once a month.

Along with its Instagram preference, Gen Z shows some fondness for in-store shopping, with 91% of the survey respondents saying they would rather shop for cosmetics in-store. The demographic also has an affinity for fast food, with Chick-Fil-A​ their No. 1 restaurant, followed by Starbucks. Food was the top spending category at 24%. Many of the findings are in line with previous research on Gen Z, which also highlight how the age group embraces both in-store and online shopping.

Separate research also shows that Gen Z also expects a lot from the brands they support, including that brands support the causes most important to them.
