* Data Collection Challenges: Tracking the number of veterinarians globally is difficult due to varying registration and reporting systems in different countries.
* Constantly Changing Numbers: The number of veterinarians is constantly changing as new graduates enter the field and others retire.
However, you can find estimates:
* The World Organisation for Animal Health (OIE) might have some global estimates, but their focus is on animal health, not necessarily vet demographics.
* National veterinary associations: Some countries' veterinary associations may have membership figures, which can provide some insight.
* Research articles: Academic studies might provide estimates, but they are likely to be outdated.
Keep in mind that any number you find is likely to be an approximation.
