What share of people say they are vegetarian, vegan, or flexitarian?

There is a growing interest in the environmental, ethical, and health impacts of our diets.

To understand patterns of food consumption we can look at market sales data – how much meat, dairy, and plant products we sell. This tells us about countries as a whole – we present this type of data here – but this doesn’t tell us about the variation within a population.

If we want to know about this variation we can rely on survey data on how people describe their dietary preferences. There is, unfortunately, a lack of long-term data on this. But we can look at recent developments.

YouGov, the polling group in the UK, surveys around 2000 adults every six months about their dietary preferences. In this article, we present the latest data and we will update this data every six months with the most recent results.

What share of British adults identify as vegetarian, vegan, or flexitarian?

These surveys ask adults which of six options best describes their dietary preferences. The six options are meat-eater, flexitarian, pescetarian, vegetarian, vegan, or none of these. Each respondent is only allowed to pick one of the six options. In the accompanying box, we provide a description of each of these diets, as YouGov describes them in their survey.

The results are shown in the chart.

These results are very similar to those from other countries. In a 2018 Gallup poll from the US, 5% of American adults identified as vegetarian, and 2% as vegan. In a wider 2018 poll from Ipsos Mori – spanning 28 countries – 5% of respondents identified as vegetarian, 3% as vegan, and a further 3% as a pescetarian. However, this poll showed very different results for some countries. For example, one in five people in India identified as vegetarian.

The YouGov survey describes these dietary choices in the following way:

• Meat-eater: eats meat and poultry (and does not describe as being mainly vegetarian)
• Flexitarian: mainly vegetarian, but occasionally eat meat or fish
• Pescetarian: eat fish but do not eat meat or poultry
• Vegetarian: do not eat any meat, poultry, game, fish, or shellfish
• Plant-based / Vegan: do not eat dairy products, eggs, or any other animal product

Breakdowns of dietary choice by age

The breakdown of UK responses by age is shown in the chart.

The two youngest demographics — the under-50s — are more likely to report being vegetarian, vegan, or pescetarian. However, this data can be noisy from one survey to the next, so there are periods when the differences between age groups is very small.

Surveys from other countries tend to report higher rates of vegetarianism in younger people. Polls from the US and other countries find this result. Averaged across the 28 countries included in the 2018 Ipsos survey, 6% of under-35s reported to be vegetarian, compared to 3% in the over-35s.

From an environmental perspective, this is good news. Eating less meat is one of the most effective ways that someone can reduce their carbon footprint.
