Coding rules
This variable differs from the DURABLE variable above on the basis of the level of change used to denote a “new” polity: DURABLE is based on a 3-point change on the POLITY index (or lapse into a special condition denoted by a “standardized authority code”), whereas the PERSIST variable is based on any change in any of the six component variables (some of these changes may not be reflected in a change on the POLITY index).
