in 2013, the csa was redefined again. the cincinnati–middletown msa was renamed the cincinnati msa. the wilmington, oh µsa remained in the csa. the maysville, ky µsa, which had previously consisted of mason and lewis counties in kentucky, was redefined as consisting solely of mason county and added to the csa. the name of the csa accordingly changed to the cincinnati–wilmington–maysville csa.
