Each category consists of the latest data available from reputable sources. This data is standardised
using minmax normalisation:
NB: where lower numbers in the initial data correspond to a better score (for example, the time taken
to learn the language), the numerator was adjusted to max(x)-x_i to ensure the normalised data is
consistent across all categories – a score of 10 is always the best result.
This value is then multiplied by 10 to create a score (between 0-10). Each city is then ranked based
on their overall average score across the key categories below, including both city-level and
country-level data, to create the global city index.
In the instance of country-level data, the country score is applied to each city within that country.
For example, if Australia has a score of 8.81 for Happiness then Sydney, Perth, Brisbane and
Adelaide all receive 8.81.
