Comparability — General

Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.
Boundary changes:

  • In 2007, Ferdows county transferred from Razavi Khorasan to South Khorasan. The two units are reported separately in 2006; therefore, we maintain this separation in both years.
  • In 2010, Alborz province split from Theran. Alborz contains Karaj, Nazarabad, and Savojbolagh counties.

There are no comparability issues. For the country of previous residence, see MIGCTRYP.
