Yemen has a population of over 23 million people who are primarily Arab and Muslim. The country's location between Saudi Arabia and Oman on the southern end of the Arabian Peninsula has influenced its economy and culture. Three key economic sectors in Yemen are fishing, agriculture, and trading/tourism, which are all supported by the country's natural environment and climate differences between northern and southern Yemen. Culturally, Yemen is known for its traditional crafts like onyx stone carving in Sana'a and wool weaving, as well as perfume production. Traditional costumes vary depending on whether one lives in the highlands, plateaus, coastal plains, or desert areas of Yemen.
