Okay kiddo, let me explain it to you. Demography means the study of the population of a country. Iran is a country in the middle east and it has about 83 million people living in it.
The people of Iran are made up of different ages, genders, religions and ethnic groups. The majority of people in Iran are Muslims with Shia Muslims being the largest group. There are also Christians, Jews, Sunni Muslims, and other religions living in Iran.
Now, let's look at the age groups in Iran. There are many children and young people under 30 years old in Iran. This means that Iran has a very young population. However, there are also many elderly people living in Iran as well.
When it comes to gender, there are slightly more men than women in Iran. However, the gap is not very big.
Iran is also home to many different ethnic groups. The largest group is the Persians, who make up about 61% of the population. Other groups include Azeris, Kurds, Arabs, and others.
In terms of population growth, Iran has seen a decline in recent years, with a falling birth rate and increasing aging population. This means that there are more elderly people and fewer babies being born in Iran.
Overall, Iran has a diverse population in terms of age, gender, religion and ethnicity. The country is experiencing changing demographics with a young population but declining birth rates and an aging population.
