Mid-year population estimates

<b>Description of Data</b>
Population estimates for the 850 Super Data Zones in Northern Ireland were published on 29th May 2025.

<b>Time Period</b>
Estimates are provided for mid-2021 to mid-2023.

<b>Notes: 
</b>1. Estimated populations are given as of 30th June for the year noted, rounded to the nearest person.<b>
</b>2. Rounding for estimates at this geographic level is independent. As such, figures may not add to higher geography totals.<b>

Methodology</b>
The population estimates for small geographical areas are created from an average of two statistical methods: 
the ratio change and cohort-component methods. The ratio change method applies the change in secondary (typically administrative) data sources to Census estimates. The 2023 small geographical area estimates use a single statistical dataset which has been created by amalgamating a series of different administrative data sources. This statistical dataset is a de-duplicated admin based estimate for the usually resident population of NI. The cohort-component method updates the Census estimates by ‘ageing on’ populations and applying information on births, deaths and migration. An average of both methods is taken and constrained to the published population figures. Further information is available at:
[NISRA 2023 Mid-year Population Estimates webpage](https://www.nisra.gov.uk/publications/2023-mid-year-population-estimates-northern-ireland)

<b>Geographic Referencing</b>
Population Estimates are based on a large number of secondary datasets. Where the full address was available, the Pointer Address database was used to allocate a unique property reference number (UPRN) and geo-spatial co-ordinates to each home address. These can then be used to map the address to particular geographies. Where it was not possible to assign a unique property reference number to an address using the Pointer database, or where the secondary dataset contained only postcode information, the Central Postcode Directory was used to map home address postcodes to higher geographies. A small proportion of records with unknown geography were apportioned based on the spatial characteristics of known records. 

<b>Further Information</b>
The next estimates of the population for Northern Ireland will be released later in 2025.

Mid-year population estimates - Northern Ireland

<b>Description of Data</b>

Notes:

1. The estimates are produced using a variety of data sources and statistical models. Therefore small estimates should not be taken to refer to particular individuals.

2. The migration element of the components of change have been largely derived from a data source which is known to be deficient in recording young adult males and outflows from Northern Ireland. Therefore the estimates are subject to adjustment to account for this and, while deemed acceptable for their use, will not provide definitive numbers of the population in the reported groups/areas. Further information is available in the Limitations section of the statistical bulletin:

[NISRA 2024 Mid-year Population Estimates webpage](https://www.nisra.gov.uk/publications/2024-mid-year-population-estimates-northern-ireland)



<b>Time Period</b>

Estimates are provided for mid-1971 to mid-2024.



<b>Methodology</b>

The cohort-component method was used to create the population estimates for 2024. This method updates the Census estimates by 'ageing on' populations and applying information on births, deaths and migration. Further information is available at:

NI Housing Stock

In line with the Rates (Northern Ireland) Order 1977, housing stock is defined as a count of properties which are valued as domestic or mixed for the purposes of rating. This refers to properties in the Valuation list at the start of each financial year which are used (or when next in use, will be used) for the purposes of a private dwelling. This excludes caravans, domestic garages, domestic stores and car parking spaces. Private refers to a self contained dwelling and not the ownership or build type of the dwelling. Housing stock includes both social and private sector dwellings in the Valuation list.

Northern Ireland Annual Descriptive House Price Statistics (LGD Level)

Annual descriptive price statistics for each calendar year 2005 – 2024 for 11 Local Government Districts in Northern Ireland. 

The statistics include:

• Minimum sale price

• Lower quartile sale price

• Median sale price

• Simple Mean sale price

• Upper Quartile sale price

• Maximum sale price

• Number of verified sales

Prices are available where at least 30 sales were recorded in the area within the calendar year which could be included in the regression model i.e. the following sales are excluded:

• Non Arms-Length sales

• sales of properties where the habitable space are less than 30m2 or greater than 1000m2 

• sales less than £20,000.  

Annual median or simple mean prices should not be used to calculate the property price change over time.  
The quality (where quality refers to the combination of all characteristics of a residential property, both physical and locational) of the properties that are sold may differ from one time period to another.  For example, sales in one quarter could be disproportionately skewed towards low-quality properties, therefore producing a biased estimate of average price. 
The median and simple mean prices are not ‘standardised’ and so the varying mix of properties sold in each quarter could give a false impression of the actual change in prices.  In order to calculate the pure property price change over time it is necessary to compare like with like, and this can only be achieved if the ‘characteristics-mix’ of properties traded is standardised.  To calculate pure property change over time please use the standardised prices in the NI House Price Index Detailed Statistics file.

Stop and Search Statistics 2017/18 - 2024/25

Stop and Search is an operational tool used to prevent, detect and investigate crime as well as to bring offenders to justice. Police officers have a legal power to stop and search members of the public in certain circumstances, from dealing with incidents of anti-social behaviour through to countering terrorism. PSNI Statistics Branch collate and report statistics on the number of persons stopped, searched, questioned and arrested under the main legislative powers.

Coastal Saltmarsh Habitat Network

In 2020, with generous funding from the National Lottery Heritage Fund, Ulster Wildlife, National Trust NI, RSPB NI and Woodland Trust NI came together to start building capacity to deliver Nature Recovery Networks in Northern Ireland. As part of the project, habitat networks maps were produced for all terrestrial and intertidal priority habitats, based on the Natural England (Edwards et al., 2020) methodology. The habitat networks comprise vector datasets that map areas of land into different network categories, based on how favourable the land is for restoration to, or creation of the priority habitat, and how effective actions in each area would be at enhancing connectivity of the priority habitat, based on proximity to existing habitat patches. A description of these network categories is provided in Table 1 in the methodology report, available at https://www.ulsterwildlife.org/sites/default/files/2022-10/EnvSys%20NI%20NRN%20mapping%20report.pdf.

The habitat network maps do not represent a fully comprehensive depiction of land cover, nor do they provide specific land management options and do not therefore replace the need for an on-site ecological surveys/appraisals. The maps are intended to function as a decision-support tool alongside other pieces of information, both from on-site surveys and data from other sources.
