What is a Primary Metropolitan Statistical Area (PMSA)?
Very large metro areas (generally over a million people) are often designated as Consolidated Metropolitan Statistical Areas (CMSAs) and divided into smaller component Primary Metropolitan Statistical Areas (PMSAs.) In this study, we focus on individual Metropolitan Statistical Areas (MSAs) and on Primary Metropolitan Statistical Areas (PMSAs), rather than the larger CMSAs. So, for example, the large Akron-Cleveland, OH CMSA has two component PMSAs: Akron, OH PMSA and Cleveland-Lorain-Elyria, OH PMSA. We present data for the two component PMSAs.
