Why Gen Z Could Soon Drive Spending Growth
In 2024, Gen X, Boomers, and the Silent Generation all account for larger shares of global spending compared with their shares of the population, with Gen X holding the largest share at 23.5%.
Millennials follow close behind with 22.5% of spending power, while making up 22.9% of the population.
However, a report by NielsenIQ and World Data Lab projects Gen Z will see the fastest growth in spending power over the next 10 years.
That’s primarily because Gen Z — which today accounts for almost a quarter of the world population — is the largest generation to date and will likely be the largest ever.
Generational spending trends offer a fascinating glimpse into how global expenditures are shaped and shared. In 2024, Gen X and Millennials dominate the financial landscape, but Gen Z’s influence is growing rapidly. As businesses and policymakers adapt to these trends, staying ahead of the curve will mean embracing the shifting dynamics of consumer power. Whether it’s targeting Gen Z or understanding the habits of established spenders, navigating spending trends is key to thriving in the global market.
