How would you estimate the market size for a new smartphone app targeting college students?

During my final year at university, I worked on a marketing project where we had to estimate the market size for a new campus-based service. I began by identifying the total number of students at our university, which was around 15,000. Then, I researched similar services and found that about 30% of students engaged with them. By multiplying the total student population by this engagement rate, I estimated that about 4,500 students would potentially use the service. This exercise taught me the importance of using data and making reasonable assumptions to arrive at market size estimates.

While volunteering for the student council, I was involved in organizing events for students. For one event, we estimated attendance by surveying our peers and analyzing previous turnout data. We found that 20% of the student body typically attended similar events. By applying this percentage to the total number of students, we projected that around 3,000 would join us. This experience helped me understand how to gather data from surveys and existing events to make informed predictions, which could also apply to estimating market sizes for products targeting students.

In my first job as a marketing assistant, I was tasked with analyzing potential markets for a new product aimed at young adults. I first researched demographic data, which revealed that there were approximately 3 million college students in the country. I also looked at trends in app usage among this demographic and estimated that about 40% of them would be interested in a new app based on our findings. This led to an estimated market size of 1.2 million potential users. This experience taught me how to combine quantitative data with qualitative insights to derive practical market estimates.
