The Year in News 2017, According to 2.8 Billion Tweets
One incredible thing about the big data era is that it allows us to crunch the numbers on pretty much anything.
Whether it’s analyzing a database of 50 million chess moves made during actual tournament gameplay, or developing a deep learning AI that sifts through billions of sensor inputs to learn how to drive a car with full autonomy – we can power nearly any analysis or algorithm with mountains of data.
Like the above examples, today’s infographic from Echelon Insights uses massive amounts of data to paint a picture of the news that wasn’t possible 10 or 20 years ago. By analyzing the words in over 2.8 billion tweets, the end result is a convincing set of visualizations that showcase the most talked about topics over the course of 2017.
The Talk of 2017
Not surprisingly, the conversation in 2017 on Twitter revolved mainly around one person – and you may have heard of him.
I love Twitter…. it's like owning your own newspaper— without the losses.
— Donald J. Trump (@realDonaldTrump) November 10, 2012
According to Echelon Insights, Trump was mentioned 901.8 million times on Twitter in the United States over the duration of the year.
Here’s how that compares to some other notable politicians:
|Politician||Mentions in 2017|
|Donald Trump||901.8 million|
|Barack Obama||164.2 million|
|Hillary Clinton||123.2 million|
|Bernie Sanders||48.8 million|
|Mike Pence||31.4 million|
Trump was mentioned about 30x more often than his VP, and 7x more often than his one-time election opponent, Hillary Clinton.
And incredibly, Trump was the number one topic of daily conversation for 95% of the year, above every other issue and topic:
There were only 17 days in 2017 where Donald Trump was NOT the top topic of conversation, and he was the #1 story every week for every audience

But putting Trump aside, here are the specific narratives that received the most attention by users in the U.S. Twitterverse.
|Topic||Mentions in 2017|
|Russia investigation||180.4 million|
|Healthcare & Obamacare||151.6 million|
|James Comey||41.8 million|
|Sexual harassment scandals||36.6 million|
|Climate change & Paris Agreement||31.8 million|
|North Korea||28.2 million|
The Russia story dominated headlines on an ongoing basis.
The alleged collusion was a constant in the news cycle from February until August, and then it picked up again in November.
It was also the top story for two of the major groups that Echelon Insights tracks, the “Liberal Base”, as well as the “Conservative Base”. However, Russia was only the second most important story for the group “Beltway Elites”, falling behind the much-discussed topic of healthcare.
Mapped: The World’s Nuclear Reactor Landscape
Which countries are turning to nuclear energy, and which are turning away? Mapping and breaking down the world’s nuclear reactor landscape.
The World’s Changing Nuclear Reactor Landscape
View a more detailed version of the above map by clicking here
Following the 2011 Fukushima nuclear disaster in Japan, the most severe nuclear accident since Chernobyl, many nations reiterated their intent to wean off the energy source.
However, this sentiment is anything but universal—in many other regions of the world, nuclear power is still ramping up, and it’s expected to be a key energy source for decades to come.
Using data from the Power Reactor Information System, maintained by the International Atomic Energy Agency, the map above gives a comprehensive look at where nuclear reactors are subsiding, and where future capacity will reside.
Increasing Global Nuclear Use
Despite a dip in total capacity and active reactors last year, nuclear power still generated around 10% of the world’s electricity in 2019.
Part of the increased capacity came as Japan restarted some plants and European countries looked to replace aging reactors. But most of the growth is driven by new reactors coming online in Asia and the Middle East.
China is soon to have more than 50 nuclear reactors, while India is set to become a top-ten producer once construction on new reactors is complete.
Decreasing Use in Western Europe and North America
The slight downtrend from 450 operating reactors in 2018 to 443 in 2019 was the result of continued shutdowns in Europe and North America. Home to the majority of the world’s reactors, the two continents also have the oldest reactors, with many being retired.
At the same time, European countries are leading the charge in reducing dependency on the energy source. Germany has pledged to close all nuclear plants by 2022, and Italy has already become the first country to completely shut down their plants.
Despite leading in shutdowns, Europe still emerges as the most nuclear-reliant region for a majority of electricity production and consumption.
In addition, some countries are starting to reassess nuclear energy as a means of fighting climate change. Reactors don’t produce greenhouse gases during operation, and are more efficient (and safer) than wind and solar per unit of electricity.
Facing steep emission reduction requirements, a variety of countries are looking to expand nuclear capacity or to begin planning for their first reactors.
A New Generation of Nuclear Reactors?
For those parties interested in the benefits of nuclear power, past accidents have also led towards a push for innovation in the field. That includes studies of miniature nuclear reactors that are easier to manage, as well as full-size reactors with robust redundancy measures that won’t physically melt down.
Additionally, some reactors are being designed with the intention of utilizing accumulated nuclear waste—a byproduct of nuclear energy and weapon production that often had to be stored indefinitely—as a fuel source.
With some regions aiming to reduce reliance on nuclear power, and others starting to embrace it, the landscape is certain to change.
How Much Do Countries Spend on Healthcare Compared to the Military?
Every year, governments spend trillions on healthcare and defense. But how much is spent per person, and how does this compare by country?
Healthcare vs. Military Spending, by Country
Keeping citizens both healthy and secure are key priorities for many national governments around the world—but ultimately, decisions must be made on how tax dollars are spent to accomplish these objectives, and funding must fall into one bucket or another.
This infographic from PixlParade examines how much 46 different countries put towards healthcare and military spending in 2018, per capita.
Head to Head: Healthcare versus Military
Data for government and compulsory healthcare spending comes from the Organization for Economic Co-operation and Development (OECD). Note that these figures do not include spending through private insurance or out-of-pocket expenses.
Meanwhile, the data for military spending comes from the Stockholm International Peace Research Institute (SIPRI).
|Country||Health spending (Per capita, 2018 US$)||Military spending (Per capita, 2018 US$)|
|Source: OECD||Source: SIPRI|
Note: There are minor discrepancies in comparing table data to original sources due to recent estimate updates. Figures for Brazil, South Africa, China, Indonesia, and India come from the World Bank (2017).
The Top 10 Healthcare Spenders
The U.S. leads the world in government healthcare spending at $9,008 per capita – over 1.5 times that of Norway, the next-highest country examined.
|Country||Per capita health spending||% of GDP||% of health spending|
While per-capita government spending on healthcare in the U.S. is the highest in the world, this has not necessarily brought about better outcomes (such as longer life expectancy) compared to other developed nations.
It’s also worth mentioning that the above figures do not cover all healthcare costs incurred by citizens, as they do not account for private insurance spending or out-of-pocket expenses. According to OECD data, these additional costs tend to be the highest in places like Switzerland and the United States.
The Top 10 Military Spenders
Israel has the highest rate of military spending per capita, and has the distinction of being the only country on this list to invest more in defense than in healthcare.
|Country||Per capita military spending||% of GDP||Total expenditure, US$M|
Although the United States comes in second place here as well, in absolute terms, the U.S. puts more money into military expenditures than many other countries combined, at almost $700 billion per year.
