[Underestimation of mortality caused by traffic in Mexico: an analysis at the subnational level].

Objective: To estimate the potential underestimation of mortality from traffic injuries at the subnational level in Mexico for a period of 15 years and to identify social and economic variables at the state level that could potentially be associated with the quality of statistical classification of deaths.

Materials And Methods: Secondary analysis of validated mortality databases for the period 1999-2013 was conducted. Using multiple imputation models, registries that could potentially be attributed to road traffic deaths were estimated and the potential underestimation of mortality due to this external cause was quantified.
