Demography

The population of Herat numbered approximately 592,902 in 2021. The city houses a multi-ethnic society and speakers of the Persian language are in the majority. There is no current data on the precise ethnic composition of the city's population, but according to a 2003 map found in the National Geographic Magazine, Persian-speaking Tajik and Farsiwan peoples form the majority of the city, comprising around 85% of the population. The remaining population comprises Pashtuns (10%), Hazaras (2%), Uzbeks (2%) and Turkmens (1%).

Persian is the native language of Herat and the local dialect – known by natives as Herātī – belongs to the Khorāsānī cluster within Persian. It is akin to the Persian dialects of eastern Iran, notably those of Mashhad and Khorasan Province, which borders Herat. This Persian dialect serves as the lingua franca of the city. The second language that is understood by many is Pashto, which is the native language of the Pashtuns. The local Pashto dialect spoken in Herat is a variant of western Pashto, which is also spoken in Kandahar and southern and western Afghanistan. Religiously, Sunni Islam is practiced by the majority, while Shias make up the minority.

The city has high residential density clustered around the core of the city. However, vacant plots account for a higher percentage of the city (21%) than residential land use (18%) and agricultural is the largest percentage of total land use (36%).

The city once had a Jewish community. About 280 families lived in Herat as of 1948, but most of them moved to Israel that year, and the community disappeared by 1992. There are four former synagogues in the city's old quarter, which were neglected for decades and fell into disrepair. In the late 2000s, the buildings of the synagogues were renovated by the Aga Khan Trust for culture, and at this time, three of them were turned into schools and nurseries, the Jewish community having vanished. In 2016, the Taliban government approved conservation work on the Yu Aw Synagogue, located in Herat's old city. The Jewish cemetery is being taken care of by Jalil Ahmed Abdelaziz.
