Millions Of Refugees Could Benefit From Big Data — But We're Not Using It

For the children of today’s Syrian and Rohingya refugees, or the future populations fleeing the threat of climate change, predictive analytics can save lives.

Today, 65 million people live as refugees or are displaced within their home countries — more than at any other point since the U.N. Refugee Agency began collecting data. Many countries have opened their borders to those displaced by war and famine, but struggle to handle the large influx.


This global crisis is often misunderstood as an overwhelming challenge for which no one can offer a satisfactory solution. But there are a set of tools that would help us, as a global society, take major leaps forward in addressing this crisis. I’m talking about predictive analytics — the statistical science (some would say art) that mines current and past data to predict future outcomes.

As a long-standing practitioner of predictive analytics, I know the field is ready to take on this challenge. But political and financial roadblocks are keeping us from addressing the crisis.

Refugee Flows

All the rage for the better part of the recent decade, predictive analytics are now used in a wide range of fields: predicting which students are in danger of dropping out of a university, helping Los Angeles social workers find possible cases of fraud, and shaving millions of unnecessary miles per year off UPS drivers’ routes. Data from the past helps the algorithms anticipate problems before they arise.

When it comes to refugees, a lack of forethought has made an already unstable geopolitical situation even worse. Few host countries had the ability to absorb refugees, and nobody fully anticipated the challenges the front-line states of Jordan, Lebanon, Turkey, and Greece would face as temporary homes for thousands fleeing to Europe. When many European states stopped accepting migrants, that only exacerbated the strain on front-line states.

Meanwhile, even willing countries like Germany left thousands stuck in refugee camps far longer than anyone thought would be required.

Migration data is already being collected by a variety of sources, including national population censuses, sample surveys, smartphones, border crossings, and administrative sources like population registers.

Such rolling data could be a game-changer for officials on the front lines of the crisis. Sophisticated analytics could help experts confidently chart where refugees are likely to head next. Policymakers, spotting signs of a future influx, might re-route refugees to different countries. This real-time data could also help organizations quickly and accurately shunt money and goods to the locales that need them the most.

Success may not come easy. But if the predictions are even small improvements on current “best guesses,” refugees would benefit from not being bottled up in overcrowded refugee camps.

In theory, perhaps algorithms could account for the political will, public opinion and the logistical capabilities of a potential host state. Similarly sophisticated statistical models have long been used to study interstate conflicts and civil wars. If front-line states are at breaking point or distracted by an ongoing regional crisis, then refugee aid organizations would be forewarned to develop alternative routes equipped to deal with refugees.

Obstacles Ahead

It requires political will for countries to work with multistate and intergovernmental organizations, share migrant pattern data, and decide how to provide resources to host countries who need them most. But, to put it bluntly, figuring out how to welcome the most refugees possible is not a top priority for most countries.

There are also major technical challenges that will need to be addressed if an international effort around predictive analytics is to succeed. One of the biggest is establishing a system to house all of the data securely. Accidental data releases could lead to targeted violence against these vulnerable populations.

Of course, these solutions would also take a hefty financial investment. Both private entrepreneurs and multinational organizations like the U.N. have devoted more attention but limited resources to the problem. Last June, Data for Democracy, a data science initiative, won a U.N.-sponsored challenge to estimate and locate internally displaced persons. Machine learning and vast amounts of online data were an integral part of the winning solution. However, challenges like these rely on volunteers rather than a permanent arm of the U.N.

The ConversationProviding humanitarian assistance to those most in need — there could be no higher purpose. While implementing a data-driven solution to the refugee problem may sound daunting, the hard work could pay off in the future — for the children of today’s Syrian and Rohingya refugees, for people fleeing the threat of climate change, or for other threats that we have not yet foreseen.

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

Bernie Sanders' presidential campaign looks to be getting a huge big shot in the arm after it's faced some difficulties over the past few weeks.

Alexandria Ocasio-Cortez, a leading voice in the Democratic parties progressive, Democratic Socialist wing, is expected to endorse Sanders' campaign at the "Bernie's Back" rally in Queens, New York this Saturday.

Fellow member of "the Squad," Ilhan Omar, endorsed him on Wednesday.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
