Data Zones also represent a relatively stable geography that can be used to analyse change over time, with changes only occurring after a Census.

Centroids for Data Zone boundaries have been created by the Scottish Government's Geographic Information Science and Analysis Team (GI-SAT) in order to provide a way to link Data Zones to other higher level geographic boundaries. Data Zone centroids do not represent the geometric centre of the feature, but rather the population weighted centre. For 2001, Data Zone centroids were calculated as the mean centre of all 2001 Census Output Areas contained within a Data Zone. In 2011, a small change was implemented following consultation with local authorities to use the median of locations of Output Area centroids contained within a Data Zone. The median has also been used for calculating the 2022 centroids, and is based on the household residents population (as opposed to the total population) to match 2011. Note that, in 2022, the centroids were calculated using data which had not had statistical disclosure control measures applied (which follows the method used by NRS to calculate Census 2022 Output Area centroids), so may not be replicable using data which has had cell key perturbation applied.
The process for creating 2022 Data Zone Centroids was automated, but the general method is as follows. The median easting and northing coordinate pair for all 2022 Census Output Areas within the Data Zone is calculated, giving a notional centroid of the Data Zone. The distance from each of the Census Output Area centroids to the notional (or median) centroid is calculated using Pythagoras' Theorem. The Census Output Area coordinate pair with the shortest distance to the median was then chosen to represent the centroid of the Data Zone.
Each 2022 Data Zone has been given a new unique code, following the Scottish Government’s standard naming and coding convention. The new S-codes for Data Zones were applied in batches per local authority, which were ordered alphabetically by name, and in batches per Intermediate Zone. The Data Zone 2022 codes range from S01013482 to S01020873 (the previous 2011 codes ranged from S01006506 to S01013481). Most Data Zones have been named according to the Intermediate Zone in which they reside, following the format ‘Intermediate Zone Name – 01’, ‘Intermediate Zone Name – 02’, etc. A small number of local authorities chose to provide names for each individual Data Zone.
Census 2022 total population, household resident population, and household counts have been supplied by NRS for each Data Zone and are included in the attribute table. All census data outputs have privacy protection applied (known as cell key perturbation) to keep the data of individuals safe. In the case of 'nested' geography hierarchies, the impact of these Statistical Disclosure Controls (SDC) means the sum of the population within Output Areas does not always match the corresponding Data Zones population totals. Similarly, the sum of the population within Data Zones might not match the corresponding Intermediate Zones population totals. The same applies when summing totals at a local authority level, i.e. the sum of the populations of all Output Areas, Data Zones, and Intermediate Zones within a local authority may not match the published local authority total.
