Yemen is very densely populated and is actually considered the most heavily populated country in the Arabian Peninsula. It is estimated that there are a little over 21 million people living in the country and it is expected to increase significantly in the coming years because it has one of the highest birthrates in the world.
The average Yemeni women give birth to six children in her lifetime. Based on this data, it is very possible that the population of Yemen could then double by 2030.
Since there are so many births every year, Yemen has a very young population. About 50% of the population is under the age of 16. This means that almost half the population is unable to vote in the presidential elections held every seven years.
The healthcare in Yemen is very poor, which is why there is a very small population of elderly. The group over the age of 65 accounts for less than 3% of the population.
Ethnically speaking, the demographics of Yemen consist mainly of Arabs. The remaining population is of immigrants from Africa and Europe. There is a very small gap between the Horn of Africa and the Tihamah region of Yemen, so it is the coastal area that has the largest African populations.
There is a social rank in Yemen, too. While the early kingdoms experienced much wealth, this died down with the invasions of Christianity. The top of the ladder is now the Sayyids, which are the descendents of Muhammad. In the past, they were government officials or landlords, though today they are often teachers and healers. Next are the Qadis, which are the scholars of Islamic law.
Below the two elite groups of Yemen’s society are the tribal people. These are led by sheiks and each tribe lives in different areas with various customs. It is possible to identify a tribe simply by the way they wrap the turban around their head. These people are usually more dedicated to their tribe than they are the country.
As for religion, 99% of the population is Islamic, so there are more Muslims throughout Yemen than any other religion. As there are still Africans and Europeans living in Yemen too, there are a few other religions, though they are few and far between.
The demographics of the country are also split by region. While most of the elite groups live in the major cities, there are also various workers that live there as well. It is the cities that have the largest split of demographics and will also have the most wealth tied to them. The lowest levels of poverty are seen in the smaller villages throughout the country and into the plains and fields.
