I started with total internet users and tried to work down from there, which felt reasonable but I kept second-guessing my assumptions mid-calculation.
Start by clarifying the scope: define what 'Google Drive users' means (e.g., active accounts, including free and paid, or monthly active users). Then use a top-down segmentation approach, breaking down the global population by key demographics and estimating adoption rates for each segment, while cross-checking with a bottom-up approach based on Google's ecosystem (e.g., Android, Gmail, Workspace).
Pro tip: Acknowledge that Google Drive is deeply integrated with other Google services (Gmail, Android, Workspace), so many users may use it passively without realizing; thus, consider both active and passive usage, and state your assumption clearly.
Define 'Google Drive users' (e.g., monthly active users, including free and paid, individual and enterprise) and the time frame (e.g., current worldwide).
Divide the global population into relevant segments: by region (e.g., developed vs. developing), by age (e.g., internet users), and by account type (personal vs. business).
For each segment, estimate the percentage of people who use Google Drive, considering factors like internet penetration, smartphone usage, and Google ecosystem prevalence.
Multiply segment populations by adoption rates to get user numbers per segment, then sum to get a total estimate.
Cross-validate with alternative methods (e.g., bottom-up from Gmail/Android user numbers) and adjust for overlaps or double-counting.
