The population of Markhors varies by subspecies and region, and the data can change over time due to conservation efforts and other factors. As of my last knowledge update in September 2021, the total global population of Markhors was estimated to be around 2,500 to 3,500 individuals. However, it's essential to consult the latest reports and research from conservation organizations and government agencies for the most up-to-date population figures for each subspecies and region. Conservation efforts are ongoing to monitor and protect these populations and work towards their recovery.
