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.

We all know that an organisation’s workforce is its most valuable asset. This is particularly true in the public sector where the majority of employees are directly responsible for supporting individuals and communities to thrive. From providing your children with a quality education and making sure your local area is safe and clean to ensuring those who need care and support receive it, these individuals play a key role in helping us achieve well-being. Wouldn’t it be good to know more about the workforce that play such an important role in all our lives? Well, look no further…

Putting names to faces…

Well, not quite, but this week we have published a new ‘Local authority workforce’ dataset in InfoBaseCymru. The dataset, which can be found in the ‘Local government’ theme, provides some headline information about the workforce of each Welsh local authority, including age, gender and salary. It will help you understand the characteristics of the current workforce and how this might change in the future.

Tell me more…

The data has been published as open data under the terms of the Open Government License (OGL), which means that the data is clear and easily accessible so that anyone can use, re-use and/or repurpose it free of charge in any format they choose.

It is part of a wider initiative to ‘open up’ data about the workforce across the entire public sector. Welsh Government have also published the same information about their workforce and we expect other organisations to make their data available over the next few months. Further information about this initiative can be found in Welsh Government’s recent ‘Data and Digital’ blog.

You can find local authority workforce data in InfoBaseCymru.

Welsh Government’s data is available in StatsWales.
