The census of 1921 was supposed to be taken on April 25th, but was delayed until 19th June due to disruption and unrest caused by the miners` lockout and the following strikes. The area is covered by Piece RG15/21726. The data is presented here by its original Enumeration District (ED). Each ED has a description of the area covered.

This census dropped some columns. These are: Years Married | Children Born | Children Alive | Children Deceased.

The Age column is now split into YEARS and MONTHS. Two new columns are Employer and Employer's Address
