Our data work

We play a central role in ensuring that data meets the needs of our ‘core’ audience by representing the views of local government in Wales around issues such as the Census, and population and migration data. We also hold a wealth of data available in maps, tables and reports in our national system InfoBaseCymru. To see the data we hold in InfoBaseCymru, use the menu on the right. You can also view some of our most popular data using the links below.


As well as the national data available in our InfoBaseCymru system, we support local government and its partners to collect other data. We can support your organisation with its data collection needs. We already work across local authority services to provide support for benchmarking activity. This work includes provision of collection forms, management of the collection activity and providing data in usable intelligent formats. We provide support across the majority of services operating in local authorities.


We can also provide support for collecting qualitative information through surveys and questionnaires. Again, the support we can provide varies based on the needs of the individual. We can help develop and test questions, as well as offering an online survey service which uses fully bilingual software. We can also provide analysis of the survey results.


Please get in touch to discuss how we can support your data needs.

Local authorities across Wales are required to report on a number of Performance Indicators each year. There are two types of indicator – National Strategic Indicators (NSIs) which are set by Welsh Government, and Public Accountability Measures (PAMs) set by local government. The information shown here is a combination of both of these sets of indicators.
