Appendix C — Data quality assessment – detailed results
Chapter 2 outlines the data quality assessment used in the statistical modelling of the 2019 InCiSE Index including summaries of the results as well as the use of the assessment results in country coverage selection and indicator weighting. This appendix provides more detailed output from the data quality assessment for all countries and territories included in the original data sources.
As discussed in Section 2.1, each set of source data was matched against a code list of 249 countries and territories produced by the “countrycode” package (Arel-Bundock et al., 2018). Of these entities, 49 have no data, with the exception of the Holy See/Vatican City all of these are overseas or dependent territories.
Section 2.3 summarises the data quality assessment results for the 200 countries and territories which had an entry in at least one of the data sources used by the InCiSE 2019 Index. The table below shows for each geographic entity the overall data quality assessment score, the percentage of all metrics the entity has data for, and an icon summarising the data quality for each of the 12 indicators measured in InCiSE 2019.
The data quality of each indicator is summarised as follows:
- A ‘green’ rating is given to those countries with a normalised indicator data quality score of 1 – the country has the best possible data available for this indicator.
- An ‘amber’ rating is given to those countries with a normalised indicator data quality score of greater than or equal to 0.5 – the country’s data quality is at least half as good as the ‘best’ possible data for that indicator.
- A ‘red’ rating is given to those countries with a normalised indicator data quality score of less than 0.5 – the country’s data quality is less than half as good as the ‘best’ possible data for that indicator.
- An ‘X’ rating is given to those countries which have no data at all for that metric.
Note only the 38 countries with an overall data quality score of 0.5 or greater were included in the 2019 InCiSE Index.
