What changed in the auto-insurance data?

PlainInsurer retains five annual state-level releases rather than overwriting the prior values. Every movement below is computed from two matched source rows; it is not an estimate or an explanation of why a policyholder's premium changed.

Method and limits

Comparisons use avg_expenditure for a jurisdiction only when both adjacent years contain a positive value. The percentage is current minus prior, divided by prior. No missing observation is filled, and no movement is attributed to a cause.

The NAIC figures are statewide averages across reported policy records. They are not quotes, forecasts, or evidence that every driver in a state experienced the displayed movement.
