Specific data on Senegal is difficult to come by but based on the aggregate data for the African region and extrapolated results there are:
households (10.7%) with internet access at home
households (9.9%) with a computer
households (0.5%) with a fixed broadband subscription
households (17.4%) with an active mobile broadband subscription
(73.5%) mobile cellular telephone subscriptions
(1.2%) fixed telephone subscriptions
Senegal is one of the countries which has lower total internet advertising growth and lower mobile internet penetration.
Only a handful of countries have relatively low mobile internet penetration coupled with low growth in total internet advertising revenue. Internet speed is one of the contributing factors. Nevertheless, these countries are still expected to have mobile internet penetration rates above 60% in 2019.
