NISRA has developed two new statistical output geographies to support the dissemination of Census 2021 statistics, namely Data Zones and Super Data Zones.
There are 850 Super Data Zones (SDZ2021) across Northern Ireland and the 3,780 Data Zones (DZ2021) nest within this geography. These two geographies nest within the 80 District Electoral Areas (DEA2014) and 11 Local Government Districts (LGD2014).
- Read our information papers to find out how the new statistical output geographies have been developed, and how other Northern Ireland geographies can be approximated
- Person and household estimates from Census 2021 are available for Data Zone, Super Data Zone and District Electoral Area
