Data is fast becoming the universal currency that defines personal status and business success. Those with unlimited access to information have a clear economic and social advantage over those for whom it is not readily to hand. For example, people who can go online can access education and the global marketplace more easily. They also have the political knowledge to demand transparency from their government.
When the term digital divide was coined in the 1990s, it simply referred to the growing inequality between people with any type of internet access and those without. On this basis, clear gaps were visible between rich and poor countries, between cities and rural communities.
The rapid penetration of mobile phones with some internet capacity into even the poorest, off-grid regions helped reduce the gap. But the digital divide has evolved to mean much more than whether someone can or cannot get online. It now incorporates wider issues such as the speed and quality of access. In the world’s most advanced mobile markets — namely Japan, South Korea and the United States — those on high-speed fourth generation (4G) networks can consume twice as much data every month as non-4G users.
This means that, however fast developing countries race to catch up, those in front continue to accelerate away. All this raises ethical questions. Some people — including one communications expert we talked to —argue that internet access should be a universal right.
Connectivity — in the form of broadband coverage and speed — has now become a major differentiator between developed and developing nations, continuing to dictate where the power resides.
This comes with a price tag. Improving connectivity requires huge investment in national infrastructure and demands government support. In this respect, a lack of connectivity now underpins, and perpetuates, global inequality.
This interactive visualisation illustrates how the digital divide has evolved.
We used a data set, compiled by Martin Hilbert from the University of California, Davis, in the United States, to measure the number and capacity of mobile and fixed-line internet subscriptions for 172 countries from 1986 until 2013.
In the scatter plot view, use the slider at the top right to show how the divide has changed over time. Using the controls on the right, you can visualise trends and focus on specific regions or the four country groupings based on national income.
The line chart view tracks the change over time for the different country income groups in bandwidth per person for fixed line subscriptions, mobile subscriptions and both subscription types together. Hover over the chart for more information.
Agriculture is vital to Bangladesh, generating more than a fifth of its gross domestic product. But despite their crucial economic role, farmers remain disadvantaged, and a lack of internet access in rural areas cuts many off from important information that could help their businesses.
Being left offline, they can’t access the latest price lists for the big local markets where their vegetables will be sold. As a result, they have to trust that wholesale traders will offer a fair price for their produce.
But a text messaging system gets around this problem by delivering up-to-date market information on a simple feature mobile phone. This allows farmers to negotiate the best price for their crops.
Our data tells the story of countries racing ahead, countries falling behind, and everything in between. But for people in every country, the value of technology is the power to connect — to missing family, government services, business opportunities and entertainment.
The argument that digital access should be prioritised in a similar way to education and healthcare is gaining momentum as a cornerstone for international development. The UN includes the provision of digital infrastructure in the new Sustainable Development Goals that will span the next 15 years. In the meantime, our individual case stories show the resilience of people working with what they’ve got in an unequal world, but who should be able to expect more.
For these people, access simply means the right to compete on a level playing field. But closing the digital divide is only the beginning. Ever-increasing access comes with a new set of problems: fears over privacy, cybercrime and the power of governments and corporations to abuse citizen’s personal data. As digital access spreads around the world, the debate around its impact is far from over.
