115 million annually

The following is a quotation from a report announced in August:

The Dr Hadwen Trust and the British Union for the Abolition of Vivisection have collaborated on a major new initiative to produce the first ever statistical analysis of global animal research numbers, the results of which have been published in peer-reviewed journal ATLA1.

Our research reveals that an estimated 115 million animals are used in laboratory experiments around the world each year. However even this massive figure could be an underestimate due to the way figures are compiled.

Despite widespread public and political interest in animal research worldwide, our research reveals that a mere 21% of countries (37 out of 179 countries) actually collect data on their national animal experiments. For the rest, no official record is kept of the animals used in their laboratories or the suffering that they might have endured.
