* No official census: There isn't a singular, official census that accurately captures the ethnic breakdown of the Hausa-Fulani population across all the countries they inhabit.
* Fluid identity: Ethnic identification in many parts of the world, including West Africa, is complex. Individuals might identify as Hausa, Fulani, or both depending on their specific family lineage, cultural practices, and local context.
* Multiple countries: The Hausa-Fulani are a large ethnic group spanning across multiple countries in West Africa, primarily Nigeria and Niger, but also including Cameroon, Chad, Ghana, and others.
Estimates:
While we can't give an exact figure, estimates vary widely:
* Some sources suggest the Hausa-Fulani population could be over 100 million people across all countries.
* Others might place the number closer to 80-90 million.
It's important to acknowledge that these are estimates based on various studies and demographic projections, and there is no definitive figure.
