In 2015, the global child mortality rate is less than half its 1990 levels, but the MDG 4 target has not been met

New child mortality estimates [PDF 4.2 Mb] released today by the United Nations Inter-agency Group for Child Mortality Estimation (UN IGME) show major progress globally. Between 1990 and 2015, the global under-five mortality rate dropped 53 percent from 91 to 41 deaths per 1,000. But this drop is still not enough to meet the global MDG4 target of a two-thirds reduction between 1990 and 2015.


In this final year of the Millennium Development Goals (MDGs), two out of six regions have met the MDG4 target: East Asia and the Pacific, and Latin America and the Caribbean, whereas the Europe and Central Asia, and Middle East and North Africa regions fell slightly short. In Sub-Saharan Africa and South Asia, progress remains insufficient to reach the target.

Open Data for Business in Kazakhstan

As the first country in Central Asia to develop an e-government initiative, Kazakhstan has been a regional leader promoting open government and open data for the past several years. Today there are more than 3.7 million users registered on the “electronic government” portal ( and on average Kazakhstani people receive nearly 40 million different electronic services a year. Open data is an integral part of the country’s open government policies around accessibility to citizens, transparency of public administration, and corruption control. The development of an open data platform was reflected in the “Information Kazakhstan – 2020″ State Program. With 200+ datasets published on their data portal in XML and JSON formats, the Kazakhstani Government is now looking to rapidly encourage and expand the use of their growing open data portal.


What Open Data Can Do for Africa's Growing Population

Back in June I rushed to take a front seat at one of the World Bank conference rooms to hear Dr. Hans Rosling speak. We had met years ago in Moldova, and just like last time, his talk was sharp, funny and full of “aha” moments.

He unveiled what the future holds: the global population will almost double by 2100, with Africa—a continent where I have worked for the last five years—leading in explosive population growth between 2015 and 2050.

Today, African governments struggle to deliver basic services to their people—including and particularly to the very poor and marginalized—across sectors, most notably health, sanitation, and education. Food security is likewise a crucial issue for the region, as are so many others: environmental sustainability, disaster risk management, economic development and others.

The future of the world’s population in 4 charts

Last week, the UN released updated population figures and projections. I just had a chance to go through them and the great key findings document (PDF, 1MB) that accompanies them.

But before I dive in, how accurate are these projections? What kind of track record do UN demographers have? The most comprehensive answer I could find was Nico Keilman’s 2001 paper which Hans Rosling refers to in this video. He notes that in 1958, when the UN projected the population in 2000 to be ~6 Billion (it was then 42 years into the future) they ended up being out by less than 5%. The short answer is: these projections are pretty good.

OK, back to the new data released in 2015: here are some of the trends that stand out for me. Note that I’m using the UN’s regional groupings rather than the World Bank’s

1) The world’s population is projected to reach 11.2 billion in 2100


There are 7.3 billion people alive today and while the world’s population continues to grow, it’s growing more slowly than in the past. We can expect to see an additional billion people added over the next 15 years, and about a billion more 10 years later, reaching a total population of 9.7 billion in 2050.

What are trade blocs and how do two of Latin America’s largest compare?

Trade blocs are intergovernmental agreements intended to bring economic benefits to their members by reducing barriers to trade.

Some well known trade blocs include the European Union, NAFTA and the African Union. Through encouraging foreign direct investment, increasing competition, and boosting exports, trade blocs can have numerous benefits for their members.

In Latin America, Mercosur and the more recently formed Pacific Alliance blocs together represent about 93 percent of the region's GDP at 2014 market prices. Who participates in these trade blocs and how do they compare?

Size, membership and performance of Mercosur and The Pacific Alliance

​The Pacific Alliance is a Latin American trade bloc formed in 2011 among Chile, Colombia, Mexico, and Peru. Together the four countries have a combined population of about 221.3 million and GDP of $2.1 trillion. The Southern Common Market (Mercosur) created in 1991, includes Argentina, Brazil, Paraguay, Uruguay, and Venezuela. Together the five Mercosur countries have 285.0 million inhabitants and GDP of $3.5 trillion.

One of the areas intended to benefit from these agreements, trade within the blocs, accounts for about 4 percent of the Pacific Alliance's total trade and about 14 percent in Mercosur.

Data Lab Link Roundup: Worm wars, csvkit, machine learning platforms, Jeep hacking, and a $12 satellite imagery receiver

Here are some things that caught our attention last week:

  • Matt Gray points out that American NOAA Weather Satellites transmit pictures via FM radio at 137MHz. Which, as Matt demonstrates, means you could use a $12 USB dongle and a laptop to receive and decode images from space.

  • “Worm Wars” may sound like an unlikely Summer blockbuster, but the debate surrounding a recent re-analysis of Edward Miguel and Michael Kremer’s 2004 deworming study has been making headlines in development circles. It provides an excellent argument for publishing data and methods alongside all research (bravo to the authors for doing so) and I’d recommend Ben Goldacre’s excellent overview of the issue, Chris Blattman’s take on it, and World Bank colleague Berk Ozler’s review of the reanalysis as well.

  • Chrysler issued a recall of about 1.4M vehicles after hackers / researchers managed to take control of a Jeep over the internet. It turns out it was possible to remotely hack the “Uconnect” system in these cars just by knowing the vehicle’s IP address. This is *really* alarming and while there are some legislative options on the table, it’s a sobering reminder that security engineering needs to be at the heart of internet connected devices, and that Commander Adama was, as usual, right.

  • Machine learning is a part of modern computer science and statistics and deals with getting systems to make and improve on predictions based on data. Commoditized machine learning platforms are starting to get pretty good, and lett you quickly try out and visualize various models. Check out Microsoft’s Azure Machine Learning, BigML, IBM Watson Analytics and Amazon Machine Learning.

  • If you’re familiar with unix-like command line tools and work with CSV files, I’d highly recommend checking out CSVKit. It’s a set of utilities for displaying, manipulating and analysing CSV files. Three years after discovering it, CSVKit and Open Refine are two of my most used “data-wrangling” tools.. And if you’re not familiar with command-line tools, CSVKit is a great place to start!

  • Finally, if you’ve not already seen it, check out the new homepage - it’s a beautiful example of mobile-friendly responsive design in action. It weighs in at 1.2Mb which these days is not too shabby, but for an overview of how not to design a fast, low-bandwidth responsive site, here’s one blogger’s take on The Verge.

MDG5: Despite progress, improving maternal health is still a challenge

This is the fifth in a series of posts on data related the Millennium Development Goals based on the 2015 Edition of World Development Indicators.

Millennium Development Goal 5  is to "Improve maternal health" and is measured against a target to “Reduce by three quarters, between 1990 and 2015, the maternal mortality ratio” and to “Achieve, by 2015, universal access to reproductive health”

In 2013, 99% of world’s 289,000 maternal deaths occurred in developing countries

According to the WHO, every day, around 800 women lose their lives before, during, or after child delivery. In 2013, more than half of all maternal deaths occurred in Sub-Saharan Africa, and about a quarter occurred in South Asia.

However, countries in both South Asia and Sub-Saharan Africa have made great progress in reducing the maternal mortality ratio. In South Asia it fell from 550 per 100,000 live births in 1990 to 190 in 2013, a drop of 65 percent. In Sub-Saharan Africa, where rates are more than double those of South Asia, they’ve also dropped by almost 50 percent over the same period.

These achievements are impressive, but progress in reducing maternal mortality ratios has been slower than the 75 percent reduction between 1990 and 2015 targeted by the MDGs. Aside from a handful of countries, no developing regions on average are likely to achieve the target. But the average annual rate of decline has accelerated from 1.1 percent over 1990–95 to 3.1 percent over 2005–13.
