What this question tests
Structured local estimation combining population, age demographics and enrollment assumptions for a metro area.
How to approach it
- Clarify scope: New York City proper versus the broader metro area, and confirm the time period, like current academic year.
- Estimate the relevant population, New York City's roughly 8.5 million residents plus commuting students from nearby areas.
- Estimate the student age population, typically college age 18 to 24, as a percentage of that total, say 8 to 10 percent.
- Add an estimate for interns specifically, a smaller subset drawn from both local students and those relocating temporarily for internships.
- Sum the estimates and sanity check against the known large number of universities and companies concentrated in the city.
What a strong answer includes
- Separates students from interns as distinct but overlapping populations, rather than conflating them into one number.
- States a clear population and age bracket assumption, landing on a range like 700,000 to 900,000 students and interns combined.
- Sanity checks against the city's dense concentration of universities and major employers as a scale reference.
Common mistakes
- Conflating New York City with the entire tri state metro area without stating which scope is used.
- Ignoring seasonal variation, since intern counts spike heavily during summer months.
Likely follow-up questions
- How would this estimate change during summer internship season?
- How would you validate this number using LinkedIn data?
