A new analysis examining over $3 billion in real consumer transactions highlights a seismic shift in global spending, confirming that younger generations—Millennials and Gen Z—are establishing a “digital-first” economy and forcing brands to rapidly adapt their marketing and loyalty strategies.
The report underscores the critical importance of these two demographics, which now collectively represent over half of the world’s population.
Millennials: The Immediate Economic Powerhouse
While both groups are crucial, the analysis confirms that Millennials currently hold the most immediate spending power due to their career stage:
“Compared to Gen Z, Millennials have 1.7x more disposable income and tend to spend more money. As they reach their peak earning years, their collective influence on global markets will expand.”
Their higher earnings and established careers make them the primary focus for current consumer spending initiatives.
Gen Z: The Lucrative Long-Term Target
Despite Millennials’ current lead in disposable income, the data suggests that Gen Z may represent the most valuable long-term revenue opportunity for brands.
“A report by World Data Lab, Nielsen, and GfK estimates the average Gen Z member will be wealthier than the average Millennials. As of now, Gen Z controls $450 billion in spending power—and that number is only going to grow as more of them enter the workforce.”
This massive and growing financial influence requires brands to prioritize long-term engagement strategies designed specifically for Gen Z.
The Mandate for Brands
The report concludes with a clear warning: successful brands cannot rely on outdated tactics. The shift in consumer demographics demands immediate evolution in marketing and loyalty programs.
“To avoid losing out on a massive share of consumer spending, [brands] have to adopt new marketing and loyalty strategies that take into account what drives younger consumers to purchase.”
Brands must now focus on strategies that resonate with the digital-first habits and values of these younger, financially influential generations to secure future market share.
