One of the questions I had today:
- How many dentist are in your country?
How would you solve this question?

Almost made the same approach, except I divided per age category (children, mature, old).
So, here's the question...which one is more directly correlated with frequency of visits? I would argue, regardless of age, you'll go to the dentist around once ayear. But, if you're poorer you can't afford to go as frquently (or at all). Remember...they're not testing just the final #...they're testing for your reasoning. Pick the categories that increase/decrease frequency the most!
How would you guess the number of visits a dentist has a day? And how does that actually correlate to number of dentists because can’t that be for the same dentist?

Classic type of case here :)
- Population of country
- Split by income/wealth level (poor, middle, upper class)
- Estimate # of visits per year per group (of course, directly correlated with socioeconimic status...benchmark off of how often you go)
- # of visits a dentist probably has per day (do not assume full capacity)
- # days/weeks worked per dentist
- Divide Q3xQ2 by Q4xQ5
- Multiply by a factor of your choice to account for doctor holidays/days off and/or non-full capacity at doctor's offices
And voila!
Bread-and-butter type of case here!

Hello!
This is a very classic type of market sizing.
I would suggest:
- Population
- Break it down in age buckets -you could also do economic level, but this one for me is more powerful-.
- Calculate number of visits per group
- Calculate how many appointments one dentist can make
Hope it helps!
Cheers,
Clara
Hi there,
Ian is spot on! Besides, it really makes sense how you reason it and not necessarily if that is the most correct answer.
There are a lot of questions on market sizing on Preplounge, and it is a nice practice!
