Estimation: student and intern headcounts for the New York region

How many students, and how many interns, are there in and around New York? Build an estimate for each number, explain how you structured it, label every assumption, and close with a figure for each and how confident you are in it. ```hint Give each number its own driver Treat the two counts separately. Ask which parts of the population can be students at all and how many of them are enrolled, then ask which of those people actually take internships and over what period you are counting them. ``` ### Clarifying Questions - Does "in and around New York" mean the five boroughs, the wider metro area that reaches into New Jersey and Connecticut, or New York State? - Which students count: K-12 pupils, college and graduate students, preschoolers, adults in continuing education? - Should interns be counted over a full year or at one moment, such as the summer peak, and do students from other regions who come for a summer internship count? - Should someone who is both a student and an intern appear in both numbers? ### What a Strong Answer Covers - A defined geography and definitions of "student" and "intern", including the time window for the intern count, settled before any arithmetic - A separate equation for each number, with interns tied to the groups that actually take internships - Labeled, round assumptions, each with a short rationale, and arithmetic that is correct and easy to follow - Adjustments that matter for New York specifically, such as interns arriving from other regions, and how overlap between the two counts is handled - A sanity check from a second angle and a final range for each number ### Follow-up Questions - Which single assumption moves the intern count the most, and how would you tighten it? - How would you check the intern figure from the employer side instead of the student side? - If the number were meant to size a product for internship seekers, which part of your count would you keep and which would you drop?
