Telephones per 100 Population is a widely used indicator to measure the telecommunication penetration in a region. It represents the number of telephone connections (fixed-line and mobile) available for every 100 individuals in a specified area, such as a country or a state. This metric, also referred to as teledensity, serves as a critical measure of a region’s access to communication infrastructure and reflects the level of technological development and connectivity. The calculation involves dividing the total number of active telephone connections by the total population and multiplying by 100. High teledensity indicates the extensive reach of telecommunication services, fostering economic growth, improved communication, and better access to information and services. Conversely, low teledensity points to challenges in connectivity, often in rural or underdeveloped areas. Policymakers use this indicator to assess and enhance communication infrastructure, bridging the digital divide and ensuring inclusive development.
