A few clarifying questions:

1. Uploads just in the US or everywhere in the world? 

2. Uploads from any specific user segment - like influencers, educators, etc.,? 

3. Uploads from app and/or website? iOS vs Android uploads? 

Assuming it's everywhere in the world, all segments and all devices. 

Estimation: 

Uploads per day = avg number of users uploading every hour * avg number of uploads/person every day*24

Avg number of uploads/person every day (for uploaders only):

Uploaders can also be divided into:

1. Active: 1-2 videos a day = 1.5 avg

2. Passive: 1-2 videos a month = 1.5/30 = 1/20 avg

3. Average: 1-2 videos a week = 1.5/7 = ~1/5 Avg

Avg number of users uploading every hour :

World population = ~7B. 

Users of YouTube = ~2B

Uploaders  = Spammers, marketers, bloggers, influencers, educators, entertainment, music, etc., 

Uploaders to Consumers ratio = <0.01 uploaders per every 10 viewers 

Given this, I would assume there are less than 1M uploaders for Youtube. 

1. Active uploaders = 10% = 100,000

2. Passive uploaders = 30% = 300,000

3. Average uploaders = 60% = 600,000

Uploads per day =

 (1.5*100000+300000*1/20+1/5*600000=150,000+15000+150000)*24=~315,000 videos a hour * 24 = 7.5M uploads a day

 

Fact-checking: 

500 hours of video are uploaded to YouTube every minute worldwide (Tubefilter, 2019). That's 30,000 hours of video uploaded every hour. And 720,000 hours of video uploaded every day to YouTube.

Hi,

I liked the clarifying questions in your answer. We could have though added what do Video uploads mean- do they include Shorts?

Though, I could not follow your equation and calculations completely.

The way I would have approached this would be as follows:

No. of Videos Uploaded to YT per day = No. of Users uploading videos in a day * Avg No. of videos uploaded per day per user.

Now, since very few users upload videos to YT daily, we can calculate this for a month and assuming uniform distribution of uploads during the month, we can divide that by 30 to arrive at the number for a day.

No. of videos uploaded to YT per day= 1/30*(No. of users uploading YT videos per month * Avg No. of videos uploaded per user per month)

World's population = 7 Bn

Let's assume 50% have access to internet globally= 3.5 Bn

Let's again assume. 75% of users with access to internet access YT once a month ~ 2.6 Bn

Assuming 1 out of 100 MAU uploads at least 1 video per month, Monthly Active Uploaders = 26 Mn

Assuming a distribution into Light, medium, heavy users

User segment# of UsersAvg # videos uoloaded per month per userTotal # of videos uploaded by the User segment per month
Light50%113 Mn
Medium30%333 Mn
Heavy20%525 Mn
Total  71 Mn

Avg No. of video uploads per day= 71 Mn/30 ~ 2.4 Mn

Hope this helps.

Clarification questions to ensure that I understand the problem better. 

Candidate: Are we interested in just US or WW. 

Interviewer: US

Candidate: Two segments upload videos a) content creator b) advertisers. Who would you want to focus on?

Interviewer: Content creators

Approach overview:

Step 1: I would estimate the number of people uploading the video in each age group

Step 2: I would estimate the average of videos uploaded per person

Step 3: I would estimate the average of videos uploaded across the whole country.

Deep dive:

Step 1: I would define the following age group a) 0 to 15 (kids) b) 15 to 25 (students) c) 25 to 40  (young professionals) d) 40 to 60 (seasoned professionals) e) 60 to 80 (seniors). I also assume 300 million people in this is country is uniformly distribued across the population.

0 to 15: Kids do not generally upload any videos, zero

15 to 25: 14% of the students in this age group that I know from the people that I mentor upload videos in an week and that is 2% per day. Students have fewer committments they love to record their life online.

There are 37 million people in group and 2% upload video per day; that is 7 million people.

25 to 40: 7% of the professionals in this age group that I know from my industry upload videos in an week and that is 1% per day. It is lower than students group becuase they have other work commitments.

There are 56 million people in this group and only 1% upload video per day. That is 5.6 million people.

40 to 60: 3.5% of the professionals in this age group that I know from my industry upload videos in an week and that is 0.5% per day. Becuase they have work and family commitments, they generate lower content than  the students and yound professionals.

There are 75 million people in this group and 0.5% only upload video, so it is 3.5 million people.

60 to 80: 0% due to their advance age, age-related ailments and less tech savines, they tend to have negiblible contribution when it comes to content creation.

number of people that upload video is 7 plus 5.6 plus 3.5 = 16 million people. It is rougly 5% of the US population.

Step 2: Number of videos uploaded by each person on an average.

Majority upload one and few upload more than one. So average will be roughly one video per person. 

Step 3: Total number of videos uploaded in a day is 16 million video uploads.
