as of december 2005, census terminology changed again, eliminating the pmsa/cmsa terminology. consolidated statistical areas (csa) combine more than one core based statistical area (cbsa). newly defined msas (metropolitan) and µsas (micropolitan) statistical areas are cbsas. from 2005 to 2013, the cincinnati–middletown–wilmington csa included the cincinnati–middletown msa (defined as the old cincinnati–hamilton–middletown cmsa), and wilmington, oh µsa (clinton county, ohio).
