Situated in the north of the province, Ferdows County, which was formed in 1944, originally included a large area (more than 78,000 km2), but its subdivisions have gradually become independent and the area now encompasses four counties (Ferdows, Tabas, Sarayan and Boshruyeh counties). After dividing the former Khorasan province into three provinces, Ferdows County was initially a part of Razavi Khorasan province,[4] but was incorporated within the borders of South Khorasan province in 2006.[5]
At the time of the 2006 census, the county's population was 61,346 in 17,539 households.[8] The following census in 2011 counted 41,626 people in 12,440 households.[9] The 2016 census measured the population of the county as 45,523 in 14,302 households.[2]
