An indicator such as educational attainment might track this. Indeed this is critical since while some LDCs have reached a high level of accomplishment in the supply side indicators, they lag in Internet use, suggesting other factors are at play besides just broadband coverage and affordability. One challenge is a limited number of Internet use surveys carried out in the LDCs necessitating a certain degree of estimation. It is estimated that by end 2017, out of the close to 1 billion people living in the LDCs, only 172 million will be using the Internet, corresponding to a usage rate of 17.5% (Figure 2.3, left). This was growth compared to 2010, when Internet penetration was just 4%. However, progression is very slow, up less than two percentage points between 2016 and 2017.
