This list includes all the people that traveled in space based on FAI criteria which defines spaceflight as any flight over 100 km (62 mi). In cases of dual citizenship the country of the astronaut primary residence was chosen. For cosmonauts that flew under the USSR flag, the country of birth was selected.
At Eurovision Song Contest countries vote for each other songs. Citizens choose, and then a top is made. The first country receives 12 points, the second 10 points, the third 8 points, and then 7, 6, 5, 4, 3, 2, 1. So each country gives points to 10 other countries.
What if we take the top ten countries from every year of Eurovision and assign them points in a similar way? Who gets to win? Well… United Kingdom. And this is the top 20
Some countries participated more than others, so they got more points. What if we took the average of points per participation? Who gets to win then? Well… United Kingdom again, with an average of 5.03 points / participation.
We are more and more everyday. Currently at 7.5 billion, the population will peak at around 11 billion people based on estimates. In Europe the peak may have already been reached.
The map shows the population growth in permilles (1‰ means that a population of 1000 people grows with 1 person in the next year) in 2018. Eastern and southern Europe countries stagnate or started to decrease, while western and northern Europe experience a slow growth. Factors that contribute to the current situation include economic development, migration, stability, human development, risk of war or violence, political environment and more.
Population growth is not constant. In the next decades the numbers will decrease overall but some countries and regions will continue to grow, probably at a lower rate. Let’s see how the countries population will change in the next 30 years compared with today.
Everybody it’s talking about pollution, climate change, the Paris agreement and how countries can reduce their carbon footprint. Let’s see what data on this topic really looks like. I’ve picked 36 countries, relevant by their population, GDP and carbon emissions and compared the data between 2005 and 2017.
Here is how the carbon dioxide emissions changed:
CO2 emissions, mil tons 2005 – 2017 comparison
There is a link between carbon emissions and GDP. More often than not, a country with higher GDP will produce more CO2 than a country with lower GDP. One can notice that in general, the more developed countries reduced or maintained their emissions, but the increase for China and India really pops up. In the same situation are most of the Asian and African countries in this study. Most of them had experienced an economic boom, and that may explain the increase of emissions.
Lets see the difference more clearly in percents and absolute value:
CO2 emissions, mil tons Difference between 2005 and 2007 (%)
CO2 emissions, mil tons Difference between 2005 and 2007
This may look bad for developing countries, but lets take a look over how many kg of CO2 are emitted per capita in each of these countries.
CO2 emissions, kg / capita 2005 – 2017 comparison
Here you can see exactly the opposite. The countries with higher GDP per capita produce more CO2 for every citizen than developing countries. However, if comparing the data between years, the same pattern described above emerges, countries that have increased their economy more also emit more CO2.
It is interesting to see how many CO2 is released into the atmosphere in a year for every dollar own by a country.
CO2 emissions, g / $ 2005 – 2017 comparison
The European Union proves that they really take climate change seriously, by having the lowest emission per dollar from the developed countries. Other developed countries don’t look that good, the US numbers are more than double than France’s, and even they are overtaken by Australia, South Korea and Canada
Nations that are not so developed like Bangladesh, Ethiopia and R.D. Congo don’t produce too much CO2. On the other hand countries that are in the middle – economically speaking – tend to emit more CO2 per dollar. It is encouraging the trend though, China halved the emissions per dollar and probably the most important conclusion seen here is that (with the exception of Saudi Arabia), every country produces “cleaner” money in 2017.
Highways play an important role in increasing people mobility and expanding the economy of the areas they connect. Trips taken via highways mean less time on the road and more time spent having fun, doing exciting activities or in the company of family and friends. Highways are also safer and easier to drive on. Not only people spend less time traveling, but also goods, thus they become cheaper and more available.
In the European Union, western countries have usually more kilometers of highway, but some eastern countries recently developed an impressive network, like Poland, Hungary or Croatia.
You might expect that Germany rules overall, but surprise, Spain has the longest network! In fact, building highways helped them raise their economy after Franco regime. Other countries also have increased their economy by constructing highways, see Slovenia who has the most km of highways per capita. On the other hand Romania lacks fast transportation but in the last decade they tripled their network.
Large nordic countries with relative small population density like Finland and Sweden have concentrated their highways in the southern regions, around the capitals while countries with small area but very populated like Belgium and Netherlands own a very dense highway network.
Having highways means also easier connections on land with your neighbours, something that is not so applicable for United Kingdom. Maybe that explains why they are in the bottom half in the density chart.
