Went with a top-down approach: US population, smartphone penetration, Android share, then Pixel's slice of that.
Use a top-down approach starting with the U.S. population, then segment by smartphone ownership and Android market share, and finally estimate Pixel's share within Android. Alternatively, use a bottom-up approach based on Google's sales or supply chain data, but top-down is more straightforward for a market sizing question.
Pro tip: Acknowledge that Pixel's share is small and often overestimated; anchor your estimate with a reasonable range (e.g., 5-10 million) and state assumptions clearly. Show awareness of Google's distribution channels and the competitive landscape.
Start with the total U.S. population (approximately 330 million) and narrow down to potential smartphone users by excluding children and seniors who are less likely to use smartphones.
Determine the percentage of the population that owns a smartphone. In the U.S., smartphone penetration is high, around 85% of adults, so apply this to your adult population.
Estimate the share of smartphones that run Android. In the U.S., Android has roughly 40-45% market share, with iOS taking the rest.
Pixel is a niche player within Android. Consider that Samsung, Motorola, and others dominate. Pixel's share of Android in the U.S. is likely around 5-10%, based on sales data and brand presence.
Multiply the numbers to get an estimate. For example: 330M * 0.8 (adults) * 0.85 (smartphone) * 0.45 (Android) * 0.07 (Pixel) ≈ 7 million. Sanity-check against known data (e.g., Google's annual Pixel sales are estimated in the millions).
