A group of blocks for tabulation purposes. Replaces the Enumeration District concept for rural areas in previous censuses.

Block Numbering Area (BNA)

It may also consist of an urbanized area of 50,000 with a total metropolitan area population of at least 100,000. The Lansing-East Lansing MSA consists of Clinton, Eaton, and Ingham Counties.

Minor Civil Division (MCD)
The primary political and administrative subdivision of a county in 28 states. They may be designated as township, town, borough, magisterial district, or gore.
