Our Gambia RDD sample connects with 1.6 million individuals for your research.

In Gambia, mobile phones have become the preferred method of communication for the majority of the population. The use of landline numbers has significantly declined over the years as mobile technology has become more affordable and accessible to the average citizen. According to the World Bank, mobile cellular subscriptions in Gambia have been steadily increasing, with a penetration rate of around 130% in recent years. This indicates that many individuals have more than one mobile phone subscription. The convenience and portability of mobile phones have made them a popular choice among Gambians, allowing them to stay connected even in remote areas where landline infrastructure may be lacking. Additionally, mobile phones offer a wide range of functionalities beyond just making calls, such as internet access, messaging, and mobile banking. While landline phones are still used in some businesses and government offices, they are becoming increasingly obsolete in the everyday lives of Gambians. As the country continues to develop its telecommunications infrastructure and expand access to mobile services, it is likely that the use of landline numbers will continue to decline in favor of mobile phones.
