In regards to the income level question, we categorise the answers into 12 various currency brackets depending on the specific country (in the respective currency, of course). The currency brackets are based on official statistics for the median income level in developed and developing countries. In the dashboard, these will be consequently categorised into low, medium or high. So the first 5 categories will be marked as ‘low’, the 6th and the 7th as ‘medium’, and the last 5 as “high”. This guarantees a fair comparison for the various countries.
