"We used a variety of credible sources to find data for each of the above categories and then ranked the countries from first to last based on this data, giving. As some factors are more important than others, the scores from ‘co-working spaces’, ‘accommodation’ and ‘sunshine/climate’ are double weighted whereas ‘remote connection’ is triple weighted – the most important factor of all.
