Usage

municipality

Format

An object of class tbl_df (inherits from tbl, data.frame) with 4542 rows and 6 columns.

Details

The 'Zenkoku Chiho-kokyo-dantai Code' is a combination of a prefecture code defined in 'JIS X 0401' and a municipality code (city, ward, town or village code) defined in 'JIS X 0402'.

These codes consists of 5 to 6 digits. The 6th digit is optional; that is a check digit. Of the remaining numbers, the first 2 digits are the prefecture code and the last 3 digits are the municipality code.

'000' as a municipality code means prefecture itself. For example, '010006' is a hybrid of '01' ('pref_code' of Hokkaido), '000', and its check digit '6'.
