#MakeoverMonday: Asylum Applications in the EU

No comments
There's way too much negativity in the news about migrants being terrible people, causing problems in their new countries, being rapists and bringing drugs. Every human being deserves to live a happy and safe life. Period.

This week's topic relates to asylum seekers in the EU.

What works well?
  • Map allows for exploratory analysis
  • Using a time series for the years
  • Informative tooltips
  • Single continuous color scale for the pending cases
  • The time series overall clearly show the growing trends.

What could be improved?
  • The filled map makes it hard to find smaller countries and to compare them with larger countries.
  • The diverging color scale of the dots on the map imply that once you get 50%, that means things are good. Is that true?
  • There's no indication of what the size of the dots represent.
  • There are too many colors fighting for attention.
  • The stacked bar charts are good for showing the overall trend, but the patterns for the individual colors are hard to determine.

What I did
I started by reading the article and noted three key statements that I wanted to focus my analysis on:

  1. Most applications for asylum were lodged in Germany, France, Greece, Italy and Spain.
  2. Citizens of Syria, Afghanistan, Iraq, Pakistan and Nigeria lodged the most applications. 
  3. Only five out of the 20 most common citizenships of asylum applicants in 2018 applied in increasing numbers compared to the previous year: Iranian, Turkish, Venezuelan, Georgian and Colombian nationals.

From there, I attempted to build charts for each of these facts. I was not able to create charts for the second and third facts as that level of detail was not provided in the data set. Instead, I changed my focus to the headlines at the top. I created BANs and some basic charts, but instead of comparing to 2017, I compared to 2015 since that was the peak of applications.
