Overview
This report presents findings on public awareness of NISRA (Northern Ireland Statistics and Research Agency) and trust in official statistics in Northern Ireland. The questions were asked in the Northern Ireland Continuous Household Survey (CHS) between September and November 2025. The report also monitors changes over time and includes comparisons with the latest available data for the Office for National Statistics (ONS), where appropriate. The figures presented in this report were obtained from a representative sample of the Northern Ireland population (985 persons) and are therefore estimates. The key findings are:
Awareness
- In 2025, almost half of respondents (48%) indicated that they had heard of the Agency before being contacted about the survey. This is higher than 2024, when 42% of respondents had heard of NISRA.
Trust
Public trust in NISRA, as an institution, is high (80%). Of those that had heard of NISRA, 92% stated that they trusted the Agency.
Public trust in the statistics produced by NISRA is also high (82%).
Value
- The statistics produced by NISRA are valued, with 88% of respondents agreeing that statistics produced by NISRA are important to understand Northern Ireland.
Political Interference
- Four-fifths (80%) of respondents agree that statistics produced by NISRA are free from political interference.
Introduction
Official Statistics in Northern Ireland are produced by Government Departments, and in some cases Arm’s Length Bodies. The data collection, production, presentation and dissemination of official statistics are governed by the Code of Practice for Statistics.
The Code of Practice for Statistics (the Code) sets the standards that those producing official statistics should apply to deliver statistics that serve the public good.
NISRA is an Agency within the Department of Finance and provides statistical services across government in Northern Ireland. The majority of Northern Ireland official statistics are produced by NISRA staff and NISRA branches can be found within all Northern Ireland Departments, and several Arm’s Length Bodies. NISRA has been measuring the levels of public confidence or trust in the Agency and in the statistics it produces since the Code was produced in 2009. These levels are monitored by the Agency and used to inform communication and marketing strategies.
In the UK, the Office for National Statistics (ONS) is the largest producer of official statistics. The most recent ONS survey, monitoring public trust in the ONS and the statistics it produces, was conducted in 2023 (Public Confidence in Official Statistics 2023 (ONS)). The ONS survey samples respondents in England, Scotland and Wales whilst the NISRA survey samples respondents in Northern Ireland. This report contains comparisons between NISRA and ONS.
Detailed tables are published alongside this report. These include the source data for all the charts and commentary and additional breakdowns (see Appendix B).
Differences are only noted in the commentary when they are likely to represent a real difference taking account of the margin of error in the sample-based estimates (see ‘Survey Estimates’ in Appendix A for further detail).
1. Awareness of NISRA
Current year, 2025
Just under half of respondents (48%) said they had heard of NISRA before being contacted about the survey.
Comparison over time
Awareness is higher than in 2024, when 42% of respondents had heard of NISRA, but similar to 2022 (49%) and 2023 (48%). Public awareness of NISRA has decreased since 2020 and 2021 (during the COVID-19 pandemic) but remains notably higher than in 2019 and earlier years (Chart 1).
Chart 1: Awareness of NISRA (2009-2025)
Comparison with ONS
Public awareness of NISRA remains lower than awareness of ONS, with nearly three quarters (74%) of respondents having heard of ONS in 2023 (the latest available data). The difference between public awareness levels for NISRA and ONS has narrowed since 2018, which was before the COVID-19 pandemic (Chart 2).

2. Awareness of NISRA Statistics
Awareness of NISRA statistics
Respondents were asked whether they had heard of specific NISRA statistics. 33% of had not heard of any of the statistics listed, while 10% had heard of all the statistics. A more detailed breakdown is available in the accompanying tables (see Appendix B).
Just over half of respondents were aware of statistics on the number of people who live in Northern Ireland (54%), statistics on hospital waiting times (53%) and the unemployment rate (53%). However, less than one in five (17%) of respondents had heard of statistics on journeys made by walking, cycling or public transport in Northern Ireland (Chart 3).

3. Trust in NISRA
Current year, 2025
Trust in NISRA as an institution is high, with 80% of all respondents trusting NISRA a great deal or tending to trust NISRA. Most of the remaining respondents (17%) didn’t know whether they trusted NISRA or not, while 3% of respondents tended to distrust or distrusted NISRA greatly (Chart 5). Trust in NISRA was higher among those who had heard of NISRA (92%). Further detail is available in the accompanying tables (see Appendix B).
Comparison over time
There is no significant difference in the level of trust in NISRA in 2025 compared with 2024 (79%) and 2023 (83%). Since 2020 (during the COVID-19 pandemic), trust in NISRA has decreased from 90% and the percentage of respondents answering ‘don’t know’ has increased from 7% to 17%. Current trust levels are comparable to those recorded in 2019 and 2016 (Chart 5).
When only respondents who expressed an opinion are considered, i.e. excluding ‘don’t knows’, trust in NISRA is higher than in 2024, similar to levels recorded between 2020 and 2023 and higher than in 2019 and earlier years.
Chart 5: Trust in NISRA (2014-2025)
Comparison with ONS
Trust in NISRA in 2025 is not significantly different to trust in ONS (83%) in 2023, the latest available data (Chart 6). However, when only those who gave an opinion are considered, i.e. excluding ‘don’t knows’, trust in NISRA is higher.
Chart 6: Trust in NISRA (2025) and ONS (2023) as institutions
Comparison with other institutions
Trust in NISRA is significantly higher than trust in the media, the NI Assembly and the Civil Service (Chart 7).
Across all institutions, trust is lowest for the media (31%) and the NI Assembly (31%), while 75% of respondents said they trust the Civil Service.
A higher percentage of respondents don’t know if they trust NISRA or not (17%) compared to other institutions.

4. Trust in NISRA Statistics
Current year, 2025
The majority of respondents (82%) trust NISRA statistics a great deal or tend to trust them while 3% of respondents distrust NISRA statistics greatly or tend to distrust them. The remaining respondents (15%) don’t know whether they trust NISRA statistics or not (Chart 8).
Trust in NISRA statistics is higher among those who have heard of NISRA as an institution (92%). Further detail is available in the accompanying tables (see Appendix B).
Comparison over time
Trust in NISRA statistics in 2025 is similar to 2024, when 83% of respondents expressed trust. Since 2020 (during the COVID-19 pandemic), trust in NISRA statistics has decreased from 90% to 82%, and the percentage of respondents answering ‘don’t know’ has increased from 6% to 15%. The level of trust in 2025 is similar to 2019 and earlier years.
When only those respondents who expressed an opinion are considered, i.e. excluding ‘don’t knows’, trust in NISRA statistics in 2025 is higher than 2024, similar to that recorded in 2020 to 2023 and higher than 2019 and earlier years.
Chart 8: Trust in NISRA statistics (2014-2025)
Comparison with ONS
The level of trust in NISRA statistics (82%) in 2025 is the same as the level of trust in ONS statistics (82%), based on the latest available data (2023). However, distrust in ONS statistics (14%) is significantly higher than distrust in NISRA statistics (3%) (Chart 9).
More respondents answered ‘don’t know’ with regard to NISRA statistics (15%) than for ONS statistics (4%).

Reasons for trusting NISRA statistics, 2025
Respondents who indicated that they trust NISRA statistics were asked their reasons for doing so and could select up to three reasons from a predetermined list (Chart 10). The most frequently chosen reasons were that official statistics in Northern Ireland are generally accurate (41%), that they trust the statistics from a personal experience (29%) and that NISRA does not have a vested interest in or manipulate the figures (25%).

Reasons for distrusting NISRA statistics, 2025
Similarly, respondents who indicated they do not trust NISRA statistics were asked their reasons for not doing so (Chart 11). The reason most frequently chosen by respondents was that the statistics alone do not tell the whole story (24%). The next most common reason given was that Government departments have a vested interest in or manipulate the figures (20%).

5. Value
Current year, 2025
The majority of respondents (88%) agree that the statistics produced by NISRA are important to understand Northern Ireland. Most of the remaining respondents (10%) don’t know, while 2% of respondents disagree that statistics produced by NISRA are important to understand Northern Ireland (Chart 12).
Comparison over time
The percentage of respondents agreeing that NISRA statistics are important to understand Northern Ireland in 2025 is not significantly different from 2022 to 2024 levels, lower than in 2020 and 2021 and comparable to 2019 and 2016 (Chart 12).
When only those respondents who had a view are considered, i.e. excluding ‘don’t knows’, agreement that NISRA statistics are important to understand Northern Ireland is higher than in 2024, similar to 2020 to 2023 and higher than 2019 and 2016.
Chart 12: NISRA statistics are important to understand Northern Ireland (2016-2025)
Comparison with ONS
The percentage of NISRA respondents (88%) who agree that the statistics produced are important to understand their country is similar to ONS respondents (87%).
While NISRA respondents are more likely to answer ‘don’t know’ (10%) than ONS respondents (4%), the percentage of respondents who disagree is notably lower for NISRA (2%) than it is for ONS (9%) (Chart 13).

6. Political Interference
Current year, 2025
Four-fifths (80%) of respondents agree that statistics produced by NISRA are free from political interference. Less than one in twenty (4%) respondents disagree that NISRA statistics are free from political interference whilst the remaining respondents (16%) answered that they ‘don’t know’ (Chart 14).
Comparison over time
Agreement that NISRA statistics are free from political interference is not significantly different to earlier years (2021 to 2024) but is lower than in 2020 (88%). However, when only those respondents who expressed an opinion are considered, agreement has increased since 2023 and 2024 and is similar to 2020 to 2022 levels.
The percentage of respondents disagreeing that NISRA statistics are free from political interference (4%) has decreased since 2024 (10%).
Chart 14: NISRA statistics are free from political interference (2014-2025)
Comparison with ONS
In comparison, 67% of respondents agree that statistics produced by ONS are free from political interference (Chart 15). This is significantly lower than the NISRA figure.

Appendix A: Methodology and Quality Information
Data Source
This report presents the results of questions relating to Public Awareness and Trust in Official Statistics in Northern Ireland that were included in the Continuous Household Survey (CHS). The CHS is one of the largest continuous surveys carried out in Northern Ireland, designed and administered by the Central Survey Unit (CSU), NISRA. Prior to 2018, the questions were included as a module within the NI Omnibus Survey but following the temporary suspension of the NI Omnibus Survey in 2018, the questions were moved to the CHS. Both surveys use probabilistic sampling to select a representative sample of the general population, aged 16 and over, resident in private households. This means that comparisons can continue to be made over time and significance tests carried out to determine if observed differences are likely to be real or due to sampling error.
Each year CSU sets the content of the CHS questionnaire in consultation with clients. The questionnaire consists of both an overall household interview, and an individual interview with each person aged 16 and over. Both the household and individual questionnaires consist of core items that are included each year, and modules that recur on a regular cycle. Core items include household and individual demographics, accommodation, tenure, internet access, environmental issues, domestic tourism, participation in sports, arts and leisure, employment status, health and section 75 classifications. Interviews are spread over 12 months from April to March, with the module on ‘Public Awareness and Trust in Official Statistics’ normally included during the Autumn months (September to November in 2025). The questions included in the 2025 module are available in Appendix C of this report.
Data Collection
The CHS is based on a systematic random sample of approximately 9,000 addresses drawn each year from the NISRA Address Register. The NISRA Address Register is maintained by Census Branch and is created by merging the POINTER database (maintained by Land and Property Services) with additional records, and removing duplicates and communal establishments. The interviews are spread over the 12 months from April to March. Data are collected through face-to-face interviews using CAPI (Computer-Assisted Personal Interviewing) or telephone interviews using CATI (Computer-Assisted Telephone Interviewing). Of the 2,340 addresses selected for interview from September to November 2025, 985 persons participated in this module of the survey.
Survey Estimates
Surveys gather information from a sample rather than from the whole population. Results from surveys are always estimates, not precise figures. This means that they have a margin of error which can have an impact on how changes in the numbers should be interpreted, especially in the short term. An estimate of the margin of error due to the sampling process can be calculated and used to produce an interval of values known as a confidence interval. This has been taken into account when carrying out significance tests.
Significance tests were carried out to determine if there were likely to be real differences between respondent groups. The significance tests were carried out at 5% significance level and only differences which were statistically significant (p<0.05) are included in this report. This means that there is at least a 95% probability that there is a genuine difference between the views of, for example, respondents in 2024 and respondents in 2025 and the difference between these two samples is not simply explained by chance.
Weighting
The CHS aspires to interview everyone aged 16 or over at a selected household, but non-response either by the household as a whole or by individuals within the household introduces non-response bias to the results. To counter this, weights are applied to the analysis on the basis of age and sex. Weights are calculated based on how the age and sex profile of the survey respondents differs from that of the latest mid-year population estimates published by NISRA. The 2024 mid-year estimates were used for the 2025/26 CHS. This weighting process adjusts the results to those that would have been achieved if the sample had been drawn as a random sample of adults across Northern Ireland, thus allowing inferences to be made about the population. The percentages given in the tables in this report are based on weighted data. The totals in the tables are not weighted.
Quality Checks
Both CAPI and CATI allow plausibility and consistency checks to be incorporated within the questionnaire to improve data quality. Data returned is coded and fully validated by CHS statistical staff, including treatment of outliers and detailed consistency checking including non-credible checks. A 100% check of all coded data is undertaken to ensure that coding procedures are of a high standard.
On receipt of the CHS data, Statistical Support Branch validate and perform quality checks on the data. Range and plausibility checks are performed for returned and derived variables and the data are also checked for ‘missing values’. The data are compared with previous years to identify any unusual trends or distributions, or values that lie outside expected norms. All anomalies are queried with CHS staff who can re-check the coding and source data.
Impact of the COVID-19 pandemic
Due to the COVID-19 pandemic, data collection for the CHS moved from face-to-face interviewing to telephone mode in March 2020. This required a reduction in the number of questions in the overall questionnaire. While the Public Awareness and Trust in Official Statistics questions were unaltered, the change in data collection mode and the number of questions may have altered how people responded to the survey. In July 2022, face-to-face interviewing was reinstated alongside telephone interviewing, thus making the survey dual modality. In 2024/25, interviewers were advised that face to face interviewing should be used where possible.
The achieved response rate for the CHS was also lower than normal in 2020/21 (16% compared to the normal achieved response rate of 55% in face-to-face mode) and slightly lower than normal in 2021/22 (41%). As a result, the 2020 Public Awareness and Trust in Official Statistics module ran for an additional three months (October 2020 to March 2021). While this maintained the precision of the 2020 estimates and has enabled comparisons with other years in the time series, the timing of the 2020 module does not align as well with other years. The provisional achieved response rate for the 2025/26 CHS is 43%. More information is available on the NISRA website.
