Happiness score of tweets in English 2021-2023

Starting from the beginning of 2021, the lowest happiness score of English-language tweets around the world was recorded on January 5, 2021, which marked the U.S. Capitol attack. On that day, the happiness score of the words used in Twitter posts in English was measured at 5.73. Each of the words were assigned a score ranging from one (sad) to nine (happy). Other significant drops in the happiness score were recorded on February 24, 2022, when the Russian invasion of Ukraine began, on May 24, 2022, when a mass shooting took place at Robb Elementary School in Uvalde, Texas, U.S., and on June 24, 2022, after the Roe v. Wade decision was overturned by the Supreme Court, having eliminated a constitutional right to abortion in the U.S. The highest happiness score of tweets in English was recorded on Christmas Day, which is mostly celebrated on December 25, both in 2021 and 2022.
