COVID-19 European Regional Tracker

Tracking the spread of COVID-19 across NUTS3 and NUTS2 regions in 26 European countries.

forthebadge cc-nc

Overview

This repository takes a stock of COVID-19 datasets for 26 European countries at the regional NUTS3 or NUTS2 level.

The Tracker is now published in Nature Scientific Data: DOI:s41597-021-00950-7

The data is released monthly on Zenodo: DOI

This repository is updated every four weeks. All raw data and scripts are available here in case more frequent updates are required. Otherwise, please feel free to request one. It takes about 30-40 minutes to run all the scripts and upload them to GitHub. Please cite the above DOIs if you are using this dataset. The underlying data structures are constantly being updated and there might be still undetected issues in the final files. For comments, feedback, error reporting, or other queries please e-mail at asjadnaqvi@gmail.com or naqvi@iiasa.ac.at.

Combining data across countries

European regions and availability of COVID-19 data

The table below shows the national regional classifications that correspond to NUTS tables. Number of regions for each NUTS level are given in brackets and the NUTS level at which the data is available is highlighted in bold. For smaller countries, NUTS 0 and NUTS 1 are the same administrative regions.

Workflow

The following workflow is used to compile the data at the NUTS3 or NUTS2 level:

The scatter plot of daily cases per 10k population at the NUTS level:

Data validation

In order to validate the data, the regional level information is aggregated up to country-level totals. These are compared with Our World in Data’s (OWID) COVID-19 tracker numbers. OWID is a key source for COVID-19-related information and is referenced frequently in scientific research and the media. OWID was utilizing country-level information provided by the European Center for Disease Control (ECDC) till November 2020. In November 2020, ECDC announced that it will switch to weekly data releases under The European Surveillance System (TESSy) where countries submit NUTS2-level data. As a response, OWID switched to the John Hopkins University’s (JHU) data, which provides COVID-19 information at the global level.

For validation, both this Tracker and OWID data is merged on a country-date combination and the difference between the daily cases is calculated. The figure above plots these differences by countries. After October 2020, the mismatch in the totals goes up significantly and persists till today. Two explanations for these trends. First, before October 2020, daily data was provided by ECDC which was taking information directly from European countries. Since this Tracker is pulling data from the countries directly, the match pre-October 2020 is very close with the exception of a few outliers. Second, since the data source of this Tracker remains unchanged, while OWID updated its source to broader (less-verified) database after October 2020, this Tracker provides a more accurate picture of country-level aggregates including regional variations. As of March 2021, ECDC is again releasing daily country-level data but gaps exist between the latest data series and the pre-November 2020 updates.
