IN SUMMARY: Millennials can no longer be treated as a single generation. The millennial age group spans 20 years, with the oldest members turning 39 years old in 2019 while its youngest members are still not even 20. This generation is no longer a demographic group united by a youthful nature, meaning the gap between the oldest and youngest millennials — in attitudes and behavior — is wider than ever.
Younger millennials are the peak age group for buying groceries at mass merchandisers: More than any other age group, they are spending more on wellbeing and fitness. Younger millennials are also more conscious shoppers: They have the highest rates of buying from retailers with good environmental records. Meanwhile, these sub-30 millennials show slightly-below-average rates of shopping for groceries online


Millennials remain a highly attractive cohort for retailers: They comprise around 22% of the US population according to the US Census Bureau and

- ounger millennials shop at mass merchandisers, spend on wellbeing and fitness, and try to buy consciously. We characterize millennials under 30 as frugal, fit and conscious shoppers.
- Millennials aged 30+ are more likely than their younger peers to look for savings, shop at traditional supermarkets and buy groceries online. We characterize older millennials aged 30+ as sensible, settled and digital shoppers.
- Millennials under 30 are the peak age group for buying groceries at mass merchandisers Walmart and Target. Older millennials tend to be the peak demographic for traditional-format supermarkets, such as Kroger and Albertsons, as well as for buying groceries online.
- The US Department of Agriculture (USDA) also observes an age divide in millennial behaviors: It reports that millennials who entered the workforce during the 2007–09 Great Recession exhibit more frugal characteristics, such as buying more food for at-home preparation instead of food away from home.
- The Food Marketing Institute and the Hartman Group found children in the house also affect digital behavior: Millennials with children under 18 are much more likely to use smartphones as part of their in-store grocery shopping trips than are those without children.
