Right now 1,269 primates live at BPRC (February 12, 2020). They were born at BPRC in breeding colonies which live in a true-to-nature environment. A limited number of monkeys take part in experiments. Since certain research projects take more than one year to be completed, some years will see higher or lower numbers. The table below shows how many monkeys took part in research in each given year.
