Islam, the Tausugs were organized into kauman and were governed by a patriarchal form of government with the individual datus as heads of their own communities. The source of law was the Adat which the Tausugs followed strictly. The Tausug arts and handicrafts have a mix of Islamic and Indonesian influences. Pangalay is a popular celebratory dance at Tausug weddings, which can last weeks depending on the financial status and agreement of the families. They dance to the music of kulintangan, gabbang, and agong. Another traditional dance of courtship is the Pangalay ha Agong. In this dance, two Tausug warriors compete for the attention of a woman using an agong (large, deep, brass gong) to demonstrate their competence and skill. A large portion of the population in Jolo is of Chinese descent. Between 1770 and 1800, 18,000 Chinese came from South China to trade and many of them stayed. In 1803, Portuguese Captain Juan Carvalho reported that there were 1,200 Chinese living in the town. The reorientation of the Sulu trade patterns caused an influx of Chinese immigrants from Singapore. Economy Industry In Jolo, most of the residents are in the agriculture industry. Agricultural products include coconut, cassava, abaca, coffee, lanzones, jackfruit, durian, mangosteen and marang. Jolo is the only municipality in Sulu that does not farm seaweed. Fishing is the most important industry; otherwise people engage in the industries of boat building, mat weaving, coffee processing, and fruit preservation. Banking There were different banks operating in Jolo and serving the people of Jolo for their needs. These included the Philippine National Bank, Metrobank, Allied Bank, Al-Amanah Islamic Bank, Land Bank and Development Bank of the Philippines. Automated teller machines (ATMs) are also available in selected bank branches.

The long-running separatist insurgency has made these Muslim-dominated islands some of the poorest regions in the nation. Jolo has faced a large degree of lawlessness and poverty. Jolo is a main stronghold for the Al-Qaeda-linked Abu Sayyaf group, and these conditions are ideal for militant recruitment. However, the situation has improved since the US has invested in developing the region. In 2007, United States Undersecretary of State for Public Diplomacy and Public Affairs Karen Hughes and US Ambassador Kristie Kenney visited Jolo to learn about US
