Younger adults make up a disproportionately large share of unbanked adults worldwide. Data from the Global Financial Inclusion (Global Findex) database show that 44 percent of youth (ages 18–25) have an account at a formal financial institution, compared with 55 percent of older adults (ages 26–64). Just 18 percent of youth report having saved formally in the past year, and 6 percent having borrowed formally. The age gap in account penetration persists across regions and across income, gender, and education groups within economies. The Global Findex database can be used to track the effects of youth-specific financial inclusion policies worldwide and develop a deeper and more nuanced understanding of how younger adults save, borrow, make payments, and manage risk
