Aradan (Persian: آرادان) is a city in the Central District of Aradan County, Semnan province, Iran, serving as capital of both the county and the district.[2]
At the time of the 2006 National Census, the city's population was 4,959 in 1,380 households, when it was in the former Aradan District of Garmsar County.[3] The following census in 2011 counted 5,626 people in 1,750 households.[4] The 2016 census measured the population of the city as 6,257 people in 2,093 households,[5] by which time the district had been separated from the county in the establishment of Aradan County. Aradan was transferred to the new Central District as the county's capital.[2]
Aradan corresponds with the ancient city of Choara (Khuwar), located in the historical region of Qumis, along the Great Khorasan Road. It is the birthplace of the former President of Iran, Mahmoud Ahmadinejad.
