* No Global Census: There's no worldwide organization that conducts regular, comprehensive horse population counts.
* Varied Definitions: "Horse" can refer to different breeds, ages, and even include wild equines like Przewalski's horses.
* Constant Fluctuation: Horse populations change constantly due to births, deaths, sales, and other factors.
Estimates:
* FAO (Food and Agriculture Organization of the United Nations): The FAO estimates the global horse population to be around 58 million as of 2020.
* Other Sources: Other estimates range from 50 to 80 million.
Important Note: These are just estimates, and the actual number could be higher or lower.
