To which European countries do Europeans migrate?

 


Migration is a huge topic in Europe and I wanted to know where people go, when they leave the country they grew up in. Luckily Eurostat has some Data about that.

There is the problem of huge population differences between the countries, so I wasn’t able to just use the absolut numbers. So I created to graphs. Once it show the migrant-population¬† relative to the host country and once relative to their origin country.


I created the graphs with the help of R and Ggplot. Code of the second graph:

ggplot(mig1,aes(y=Host,x=Origin,fill=sharehostpop))+
 geom_raster()+
 theme_gray()+
 coord_equal()+
 scale_fill_distiller(palette="YlOrRd", direction = 1,na.value=NA,trans='log1p')+
 theme( 
 axis.text.x=element_text(angle = 45, hjust=.1),
 legend.position = "bottom")+
scale_x_discrete(position="top")+
 scale_y_discrete(limits=names(table(droplevels(mig1$Host)))[length(names(table(droplevels(mig1$Host)))):1])+
 labs(y="Host-Country",x="Origin-Country",fill="Share of Population in Host-Country (%)",
 title="Biggest groups of European immigrants in Europe (2017)",caption="Note: Missing countries had no Data avaible or were so small, that they distored the scale.

A dot-map of Europe

This map is a more leaning on the aesthetic- then data-side. The size of the dots correlates with the size of the population in that place. The color has no meaning and is just there to look nice. For the division of places I used the NUT3 standard which is quite useful, but has its problems if you use it to compare countries. Continue reading “A dot-map of Europe”

Growth of European Countries relative to 1950


How did the populations of European countries grow after the end of the 2nd world-war? To answer this question I downloaded population-data from the United Nations. I picked 1950 as my default year and looked how it developed from there.

The relation of the Swiss immigration-referendum and the share of foreigners

Foreigners-ImmigrationReferendum

In 2014 Switzerland had a referendum about the initiative “against mass immigration”. I passed with 50.33 percent to the surprise of most people. The result caused a turmoil in Swiss politics. The goal of the initiative was to introduce upper limits for immigration. This seemed to contradict the Schengen-agreement with the European Union. Implementing it would probably mean the end of free movement and risk the Bilateral treaties with the EU, which are an important pillar of the economic success of Switzerland.

Which European country has the highest share of foreign born population?


For this graph I was interested in which countries had the highest immigration in recent times. I used data from the European Census 2011. Unfortunately the data is a bit old and there doesn’t exist a new version yet. Because Asia can mean a lot of things, I checked from which countries the most people come from. I didn’t count Russia as Asian here.

Because the numbers are quite old, I looked into recent numbers from Germany, where many would expect the most change. I found the Data on the website of the federal bureau for statistics. Unsurprisingly the number of immigrants has risen.
