How Big is the Side Hustle Economy?

The side hustle economy has been growing rapidly due to the rise of freelancing, e-commerce, and digital platforms. Recent statistics highlight the scale of this phenomenon:

  • In the United States, 36% of adults currently have a side hustle. This translates to nearly 80 million people, showing that side hustles are becoming a critical part of modern work culture (Source: Bankrate).

  • In the United Kingdom, 39% of adults have a side hustle, with 61% of Gen Z and 55% of millennials pursuing additional sources of income (Source: Luisa Zhou).

  • In Canada, 53.4% of adults engage in side hustles, with younger workers capitalizing on flexible job opportunities (Source: Luisa Zhou).

  • On a global scale, the gig economy was valued at $3.7 trillion in 2023 and is projected to continue expanding as more individuals embrace freelancing, remote work, and digital entrepreneurship (Source: Staffing Industry Analysts).

These figures highlight a fundamental shift—workers are no longer relying on a single paycheck. Instead, they are diversifying their income streams to adapt to economic uncertainty and changing job markets.
