I want to know the answer to the following question:
Ethnic minorities such as Azerbaijanis make up what percentage of Iran's population?
All the background I'm provided with is that "As with the spoken languages, the ethnic group composition also remains a point of debate, mainly regarding the largest and second largest ethnic groups, the Persians and Azerbaijanis, due to the lack of Iranian state censuses based on ethnicity.". Is that enough to answer the question?
Answer: no
