The line graph gives information about the percentage of UK adolescents following a vegetable diet over the course of 60 years starting from 1960.
In general, there was a fluctuation in the percentage of UK teenagers being a vegetarian. At the end of the period, it was higher than the beginning.
In 1960, there was only a small percentage of UK young people interested in vegetarism, around 1%. From 1961 to 1980, the percentage rose significantly by 15%, from 2% to 17% and it reached its peak in 1980 with about 17%. Since 1980, the percentage dropped considerably, from 16% in 1980 to about 6% in 1993. Although the percentage of UK young people being a vegetarian had a slight increase in 1994 with 8% but it decreased by 4% in 1997. From 1997 to 2010, there had been a gradual rise, from 4% to over 10% before it almost stayed the same to 2020.
