According to the Claims Conference, an organization that provides services and support to Holocaust survivors, there were approximately 190,000 Holocaust survivors still alive in the world as of 2021. The survivors are mainly concentrated in Israel, the United States, and Europe, with smaller communities in other countries around the world.
Please note that this number is an approximation and may vary depending on different estimates and sources. As the number of Holocaust survivors continues to decline due to natural causes, it's important to preserve their stories and memories to honor the victims and the impact of the Holocaust.
