In April 2019, the Gross National Happiness (GNH) Index was launched. This index relies on Big Data and measures the evaluative mood of a nation in real-time, the first of its kind. A live feed of tweets is extracted from Twitter, and sentiment analysis is used to determine each tweet's sentiment using Natural Language Processing. Subsequently, they use the sentiment scores to derive an hourly happiness score, ranging from 0 to 10. Additionally, each tweet's underpinning emotions are analysed. Currently, a distinction is made between eight emotions: sadness, surprise, disgust, anticipation, fear, anger, trust, and joy. When the GNH Index was launched in 2019, it initially focused on three countries; South Africa, New Zealand and Australia. Subsequently, in June 2020, the GNH project expanded to include seven additional countries, mainly from Europe. For more information on the GNH, please refer to the website https://gnh.today.
