What this question tests
Fermi estimation using plausible daily media consumption habits.
How to approach it
- State you'll estimate via a daily reading habit and multiply by days per month.
- Assume an average adult reads or skims a certain number of articles per day, e.g. 3 to 5.
- Multiply by roughly 30 days to get a monthly estimate.
- Adjust for the fact that not all adults read news daily, applying a rough participation rate.
- State the final range and flag the daily-habit assumption as the most uncertain input.
- Note how this differs by age group.
What a strong answer includes
- Builds from a daily habit assumption up to monthly rather than guessing the monthly figure directly.
- States the per-day article count as an explicit, labeled assumption.
- Adjusts for non-uniform reading habits across the population rather than assuming everyone reads daily.
- Gives a range and names the weakest assumption rather than a single confident number.
Common mistakes
- Not distinguishing deep reads from quick skims, which would change the number by an order of magnitude.
- Assuming uniform reading habits across all adults.
Likely follow-up questions
- How would you define 'reading an article' versus just skimming a headline?
- How would this number differ for younger versus older adults?
