Checking in on how nations are coping with COVID-19


It has been some five months since the COVID-19 pandemic dawned on people's consciousness and three months since many nations went into some form of compulsory social distancing to help manage the pandemic. In this context, I thought it time to reflect on how nations have performed.

This required me to establish a benchmark for measuring success. For this I have selected four factors:
  • how bad did the pandemic get at its peak in the nation (indicated by daily new deaths and daily new cases)
  • how bad is the pandemic currently (indicated as aboved)
  • how well have nations done in reducing the pandemic from its peak (as a proportion of that peak in daily new deaths and daily new cases)
  • what is the case fatality rate for the nation (total deaths over total cases). 

The population and COVID data I used for this analysis comes from the European Centre for Disease Prevention and Control.

For simplicity, I will limit my analysis to nations with a population of at least 1 million people.

To enable comparability between large and small nations, I am going to focus on cases and deaths per million population.

As I am working with noisy administrative data, I will do the analysis based on a 14-day rolling average. This irons out the tendency in many nations to under-report on weekends. It also helps reduce the impact of data spikes when nations fess up to additional deaths or cases not previously recorded.

Because the distributions of these data can have nation-states bunched around certain data points, with long tails and outliers, I have decided the group the data into quintiles (5 equal groups), and create an index score from averaging the quintile result across the seven categories:
  • average daily new cases per capita at each nation's peak peak
  • the most recent result for average daily new cases per capita
  • the percentage decline from the peak average daily new cases per capita and now
  • average daily new deaths per capita at the peak
  • the most recent result for average daily new deaths per capita
  • the percentage decline from the peak in average daily new deaths per capita and now
  • the case fatality ratio

Before we get to the per-capita charts, let's quickly identify our top ten:
  • Top 10 current cases per million population: Qatar, Bahrain, Chile, Kuwait, Peru, Armenia, Oman, Brazil, Belarus, and Panama
  • Top 10 national peak cases per million population: Qatar, Bahrain, Chile, Kuwait, Peru, Spain, Ireland, Singapore, Armenia, and Oman
  • Top 10 current deaths per million population: Sweden, Brazil, Peru, United Kingdom, Mexico, Chile, United States, Canada, Panama, Armenia
  • Top 10 national peak deaths per million population:  Belgium, Spain, France, United Kingdom, Italy, Ireland, Sweden, Netherlands, United States, Ecuador

The following charts show the per-million-population daily cases and deaths data for selected nations. I should note that as the cases data for Qatar is such an outlier, I have adjusted the y-scale in the other case charts where Qatar in not highlighted.





























Which brings us to the score for each nation, reflected in the choropleth map at the top of this post:
