The Financial Times has created a series of data visualizations illustrating the digital divide between the suburbs and inner cities in Great Britain. Maps show that while internet speed is typically faster in urban areas than rural ones, broadband speeds in the center of cities lag behind performance in the suburbs. There are a number of factors driving the speed discrepancy between suburbs and the urban core—a phenomenon not unique to the UK. Wealthier suburbs have a higher demand for greater speed, attracting more investment. Also, once density passes a certain point, complexity in permitting and construction drive up costs of construction. Users can search postcodes in an interactive chart to see how an area compares to the rest of Great Britain for broadband speed.
