Only around 1.1% of the world's population is vegan, but this percentage is growing. For example, in Germany the number of vegans approximately doubled between 2016 and 2020 to 2% of the population, while a 2.4-fold increase between 2023 and 2025 to 4.7% of the population has been reported in the UK. Many people cite health benefits as their reason to go vegan: moving from a typical Western diet to a vegan one can lower the risk of premature mortality from noncommunicable diseases by an estimated 18% to 21%.
