Hi there,

This would be another top-down approach (like the rice question you've asked).

I would recommend the following approach:

Understand the approximate population of Sierra Leone

Split the population by age (The logic here is that social media usage changes most by age) Note: Most countries in africa have a narrow population pryamid...meaning there are a lot more young people than old people.

Estimate the % of each age band with eletronic devices and internet (You should note income splits by age here: i.e. the youngest and the oldest might not be able to afford these)

Estimate the % using social media by age band (i.e. teenagers, young adults, adults, and elderly) (you should make note of 1) Where these groups are (i.e. city vs rural)...i.e. if they're rural (higher % elderly), they're less interested in social media

For the same age bands: estimate the daily frequency of social media use, for those using it

Multiply out and viola :)

Hi - one example approach outlined below

• Population of Sierra Leone - 7.5M
• Assume equal distribution for simplicity and life span of 60 so you get 125,000 at every year till 60
• People that post on social media, assume they are 15-55 (or any other reasonable age group) - that os 40*125k = 5M
• Assume that 2M heavy users, 2M Med/Light users ,1M rare users
• Heavy users - on avg 3 selfies a week, medium -1 and light less than 1 a week (say one a month)
• That gives you ~ 850K (heavy), 550K medium and 35K light - so total of 1.45M selifes a day in Sierra Leone

Hello!

I would do:

1. Sierra Leona´s population calculation
2. % that have a device (not only mobile phone, also tablet works for selfies)
3. # of selfies a person takes/week
4. # of those that get posted

Hope it helps!

Cheers,

Clara
