Coverage
Our Andorra RDD sample connects with 0.08 million individuals for your research.
In the small country of Andorra, located in the Pyrenees mountains between France and Spain, the use of landline numbers is becoming increasingly obsolete. With a population of around 77,000 people, the majority of residents now rely on mobile phones for communication. The convenience and mobility of mobile phones have led to a decline in the use of traditional landlines. According to a report by the World Bank, Andorra has a high mobile cellular subscription rate of 105.7%, indicating that many individuals have more than one mobile phone. This high penetration rate suggests that mobile phones are the preferred choice for communication in Andorra. Additionally, the availability of affordable prepaid mobile plans has made it easier for residents to access mobile services without the need for a landline. Overall, it can be concluded that in Andorra, mobile phones are more frequently used than landline numbers, and this trend is likely to continue as technology advances and mobile networks expand.
