The Innovation Growth Index measures the growth of key innovation indicators for the most recent years for which data is available (in this case, 2017-2018 and 2018-2019). The index requires KZN-specific data, data availability for the 2018 and 2019 years, and data that represents a raw number (as opposed to a ratio or percentage). Only indicators within the ‘people’ and ‘investment’ categories met these requirements. The two highest impact indicators from each category were selected. The few indicators used in the index are a limitation, however, the index will grow and improve as data quality and availability improves each year. The Growth Index represents the average growth of the four selected indicators. The Growth Index for 2019 (-21) shows significant decline compared to 2018 (12).
