Media (R)evolutions: Global Mobile Data 2014 - Traffic Growth and Forecast

Roxanne Bauer's picture

New developments and curiosities from a changing global media landscape: People, Spaces, Deliberation brings trends and events to your attention that illustrate that tomorrow's media environment will look very different from today's, and will have little resemblance to yesterday's.

Every day, people create 2.5 quintillion bytes of data- this astonishing rate means that 90% of the data in the world today was created in just the last two years! 

Sources of data include mobile phones, tablets, the Internet of Things, and social media. Mobile technologies, in particular, have contributed to the growth of mobile data as new apps are created and used every day to to send text, make mobile payments, watch multimedia, or shop to name a few.  These activities all leave a digital footprint-- big data that can be analyzed. 

The graphic below illustrates recent global mobile data traffic growth by region and provides a forecast for the coming years:

Are You the Perpetrator of Your Own Loss of Privacy?

Roxanne Bauer's picture

Exploring ideas, innovations and fresh approaches to our world is at the heart of the public sphere. People, Spaces, Deliberation brings you significant voices from academia and the practice of development through a series of interviews.

Do conventional notions of privacy still exist? Are we trading privacy for convenience?  If privacy is a thing of the past, is this a bad thing?

According to Professor Silvio Waisbord, an expert on global media, development, and social change, the answer is mixed.  People trade the downsides of losing privacy in exchange for convenience, simplification, and other social factors. 

The interesting question for him is, "What do people typically do when they are confronted with the fact that you are one of the main perpetrators of your loss of privacy. What do you do about that? Are you willing to make changes about that?"

Can Big Data Stop Wars Before They Happen?
Foreign Policy
It has been almost two decades exactly since conflict prevention shot to the top of the peace-building agenda, as large-scale killings shifted from interstate wars to intrastate and intergroup conflicts. What could we have done to anticipate and prevent the 100 days of genocidal killing in Rwanda that began in April 1994 or the massacre of thousands of Bosnian Muslims at Srebrenica just over a year later? The international community recognized that conflict prevention could no longer be limited to diplomatic and military initiatives, but that it also requires earlier intervention to address the causes of violence between nonstate actors, including tribal, religious, economic, and resource-based tensions. For years, even as it was pursued as doggedly as personnel and funding allowed, early intervention remained elusive, a kind of Holy Grail for peace-builders. This might finally be changing. The rise of data on social dynamics and what people think and feel -- obtained through social media, SMS questionnaires, increasingly comprehensive satellite information, news-scraping apps, and more -- has given the peace-building field hope of harnessing a new vision of the world.

The economist who revealed how media bias works
Quartz
It’s heady company. When he won the John Bates Clark Medal earlier this month, University of Chicago economics professor Matthew Gentzkow suddenly found himself among legends such as Paul Samuelson and Milton Friedman. Both are past recipients of the award, which the American Economic Association bestows on the American economist under the age of 40 who “who is judged to have made the most significant contribution to economic thought and knowledge.” Plenty of past winners have worked in familiar areas, such as wage dynamics or health economics. Gentzkow’s work is less orthodox: an interesting mix of the history and micro-economics of the media world.

Big data, causal inference and ‘good data mining’?

Last week I attended the International Development Conference at the Kennedy School of Government, joining a session on social protection. The conference is organized by KSG students (kudos to the students for their hard work in making it happen and interesting!), and has a format with no presentations and informal panel discussions with invited speakers.

The Transformative Impact of Data and Communication on Governance: Part 3
Brookings Institution
How do digital technologies affect governance in areas of limited statehood – places and circumstances characterized by the absence of state provisioning of public goods and the enforcement of binding rules with a monopoly of legitimate force?  In the first post in this series I introduced the limited statehood concept and then described the tremendous growth in mobile telephony, GIS, and other technologies in the developing world.  In the second post I offered examples of the use of ICT in initiatives intended to fill at least some of the governance vacuum created by limited statehood.  With mobile phones, for example, farmers are informed of market conditions, have access to liquidity through M-Pesa and similar mobile money platforms.

Cashing in: why mobile banking is good for people and profit
The Guardian
Using digital finance to tackle development problems can improves lives, and offer innovative companies handsome rewards. Whether it is lack of access to water, energy or education, development professionals are well versed in the plethora of challenges facing billions of people. The traditional approach to solving these problems has been to think big – in terms of the millennium development goals, government aid programmes, or huge fundraising campaigns. But there are dozens of startups and larger companies with innovative ideas who are approaching these challenges in new ways using digital finance.

Igniting the Data Revolution Post-2015 Now

Grant Cameron's picture

What sparks a revolution? And what helps keep the transformational power of a revolution alive?  When Jim Yong Kim became World Bank Group president less than two years ago, he stated that one of his first priorities was to position the World Bank Group as a “solutions bank.”  Most recently, during his speech last Tuesday at the Council on Foreign Relations, Kim discussed the Bank’s efforts to invest in effective infrastructure, including data systems and social movements to empower the poor.

These three words – solutions, data and the poor – from my perspective, point to this: the data revolution needs to be transformational and we must act now.   Unless we fully embrace this data revolution as a bold, timely opportunity to engage citizens, identify successful case studies, leverage global partnerships and technology, strive to learn from the private sector and truly aim to be innovative, we just may miss out on keeping this revolution alive.  And while it is good news that the UN High Level Panel Report on the post-2015 development agenda confirms that the data revolution is high on the political agenda, we must also gather evidence and vigorously commit to an inclusive plan to meet this goal.

How I Use World Bank Data: Researching Access to Electricity

Dong Yang's picture

Dong Yang is a first-year Ph.D. student at the University of Chinese Academy of Sciences. He majors in public administration. Dong got in touch with us to share his experience using World Bank Data as part of his research.

William Shakespeare once wrote, “There are a thousand Hamlets in a thousand people’s eyes.”  Similarly, different people have different understandings of database services. Some people believe it is a type of personalized service, some believe it’s a value-added service, while others believe it’s a solutions-driven service. For us students, database services are vital to our research.
 
As a form of knowledge service, databases should be adapted to the changing needs of users, supporting both knowledge consumption and knowledge creation. A good database helps not only to convert “data” into “outcomes,” but also achieve the goal of pooling wisdom and creating knowledge by enhancing a user’s creativity with its rich resources and services. In my view, the World Bank’s Open Data has truly fulfilled these functions.

Data and Development

Mahmoud Mohieldin's picture

WASHINGTON, DC – Since the turn of the century, the international development community has rallied behind the Millennium Development Goals, which set specific targets in eight key areas, including poverty, child mortality, and disease, to be achieved by 2015. In formulating the post-2015 development agenda, measuring the MDGs’ successes – and identifying where progress has lagged – is critically important. And that demands more and better data.

To be sure, international institutions and many developing countries have invested significantly in improving data collection to track better their performance against MDG targets. In 2003, only four countries had two data points for 16 or more of the 22 principal MDG indicators; by last year, that figure had soared to 118 countries.

But development data remain a scarce resource in the developing world. Given their value in measuring – and propelling – social and economic progress, this shortage must be addressed urgently. A catalyst is needed to expand the production and use of development data. With this in mind, the high-level panel on the post-2015 development agenda is right to call for a global “data revolution.”

Big Data in Education in 2025: A Thought Experiment

is making me confused .... and hungry

Each January, about 85 government ministers or so -- together with some members of their staffs, leaders of the education departments in international organizations, large NGOs and multinational companies, and other 'high level decision makers' -- gather in London to speak informally about topics of common interest during the Education World Forum, which bills itself as the 'world's largest gathering of education and skills ministers'. It's a rather unique and impressive collection of people with the power to make decisions affecting hundreds of millions of students and teachers around the world. This annual meeting was previously called the 'Learning and Technology World Forum'; despite dropping the word 'technology' from its official title a few years ago, talk of tech was inescapable during this year's Forum, whether onstage or in the hallways. If I were asked to identify three general themes that permeated discussions throughout this year's three-day event, they would be 'technology', 'systems' and 'data'.

For many groups, the Education World Forum offers a high profile venue to announce new initiatives, launch new publications, and present findings from recent research. My boss at the World Bank, Elizabeth King, for example, officially launched a new 'SABER' education data technology tool during her keynote speech on the second day ("When it comes to learning, education systems matter"). While the links between these three themes were perhaps not always explicit in Beth's speech, the important role that new technologies will play in helping education systems to collect and analyze key data about the health of the education system, especially as pertains to whether or not students are learning (and, if so, how), was echoed and amplified by many of the other speakers in both EWF plenary sessions and related side events.

---

While the Forum has become increasing open over the years, embracing the use of social media throughout much of the agenda, for example, and quickly making available on YouTube key speeches and presentations, the off-the-record ministerial exchange sessions that happen on the second day are, as per the EWF social media policy, meant to be a largely Twitter-free zone. The hope is that, if/when/where given space to ask the 'dumb' questions of their peers, and freed from having it reported that someone, in response, provided some 'dumb' answers, Forum participants might feel comfortable enough to have what turn out to be some rather smart conversations about topics for which they had not been prepped, and about which no formal position papers had been prepared back home.

At one of the informal Forum ministerial exchange sessions a few years ago, rather exasperated that much of the conversation was concentrated on discussions of the lowest costs that various countries had paid for student laptops, I posed the following scenario, and question, as a sort of 'thought experiment':

#4 from 2013: Numbers Are Never Enough (especially when dealing with Big Data)

The newest trend in Big Data is the personal touch.  When both the New York Times and Fast Company have headlines that trumpet: “Sure, Big Data Is Great. But So Is Intuition.” (The Times) and “Without Human Insight, Big Data Is Just A Bunch Of Numbers.” (Fast Company) you know that a major trend is afoot.

So what’s up?

The claims for what Big Data can do have been extraordinary, witness Andrew McAfee and Erik Brynjolfsson’s seminal article in October in the Harvard Business Review: “Big Data: The Management Revolution,” which began with the showstopper:  “‘You can’t manage what you don’t measure.’”  It’s hard not to feel that Big Data will provide the solutions to everything after that statement.  As the HBR article noted:  “…the recent explosion of digital data is so important. Simply put, because of big data, managers can measure, and hence know, radically more about their businesses, and directly translate that knowledge into improved decision making and performance.”
