How many chimpanzees were left in 1990?

In 1990, it is estimated that there were approximately 1 to 2 million chimpanzees remaining in the wild. However, precise numbers are difficult to ascertain due to varying definitions of populations and habitat loss. Over the years, habitat destruction, poaching, and disease have significantly impacted their numbers, leading to a decline in their population. Today, chimpanzees are classified as endangered, with current estimates suggesting that their populations have decreased significantly since 1990.
