Census 2011 - Workplace Zones Centroids
Workplace Zone (WZ) centroids are point features that represent the ‘master postcodes’ for WZs. The centroid, or ‘master postcode’ was selected using an algorithm which calculates the postcode centroid within a WZ which has grid references closest to the worker-weighted centre of the DZ. These centroids / ‘master postcodes’ can be used to link WZs to other (higher level) geographies and produce a 'best-fit' match. They have been created by the National Records of Scotland (NRS), based on the WZ boundaries which were produced on behalf of NRS by the Office for National Statistics (ONS).
WZs were a new output geography for Census 2011, initially produced using workplace data from the 2011 Census for England and Wales rather than the UK as a whole. They are designed to supplement the Output Area (OA) and Super Output Area (LSOA and MSOA) / Data Zone (DZ) geographies that were introduced with the 2001 Census, and have been constructed from OAs, or sub-divisions of these called postcode-level building-blocks. While OAs are designed to contain consistent numbers of persons based on where they live, WZs are designed to contain consistent numbers of workers, based on where people work. Following publication of WZs for England and Wales, coverage was subsequently extended to include Scotland and Northern Ireland using 2011 Census data to create a UK set of WZs produced by the ONS on behalf of NRS and the Northern Ireland Statistics and Research Agency (NISRA). WZs are designed to be a more suitable output geography for publishing workplace statistics.

- You can customize the template to suit your needs. You can add and remove fields and fill out default information (e.g. contact details). Fields you can not change in the default view may be accessible in the more comprehensive (and more complex) advanced view. You can even use the XML editor to create custom structures, but they have to be validated by the system, so know what you do :-)

Workplace Zone (WZ) centroids are point features that represent the ‘master postcodes’ for WZs. The centroid, or ‘master postcode’ was selected using an algorithm which calculates the postcode centroid within a WZ which has grid references closest to the worker-weighted centre of the DZ. These centroids / ‘master postcodes’ can be used to link WZs to other (higher level) geographies and produce a 'best-fit' match. They have been created by the National Records of Scotland (NRS), based on the WZ boundaries which were produced on behalf of NRS by the Office for National Statistics (ONS).
The general method for calculating the centroids / ‘master postcodes’ is as follows. The mean easting and northing coordinate pair for all postcodes within the WZ is calculated, weighted by the number of workers per postcode, giving a notional centroid of the WZ. The distance from each of the postcode centroids within the WZ to the notional (or mean) centroid is calculated using Pythagoras' Theorem. The postcode coordinate pair with the shortest distance to the mean was then chosen as the ‘master postcode’ to represent the centroid of the DZ.
WZs were a new output geography for Census 2011, initially produced using workplace data from the 2011 Census for England and Wales rather than the UK as a whole. They are designed to supplement the Output Area (OA) and Super Output Area (LSOA and MSOA) / Data Zone (DZ) geographies that were introduced with the 2001 Census, and have been constructed from OAs, or sub-divisions of these called postcode-level building-blocks. While OAs are designed to contain consistent numbers of persons based on where they live, WZs are designed to contain consistent numbers of workers, based on where people work. Following publication of WZs for England and Wales, coverage was subsequently extended to include Scotland and Northern Ireland using 2011 Census data to create a UK set of WZs produced by the ONS on behalf of NRS and the Northern Ireland Statistics and Research Agency (NISRA). WZs are designed to be a more suitable output geography for publishing workplace statistics.
