What is data science?

In this blog we’ll explore what we mean by ‘data science’ and how it can impact our work at Social Care Wales.

In today's world, data is a driving force behind innovation and evidence-based decision making across different fields, including health and social care. Data science combines statistics and computer science to provide insight and help us plan for the future. It’s a broad field that uses different tools, techniques and algorithms to find meaning in complex data.

Data is collected and prepared before being analysed to find trends and patterns. Techniques like machine learning can then be used to build models that can predict future events or outcomes, and to help make data-driven decisions.

Machine learning uses algorithms and data to train a machine to make smart decisions, without the need for specific programming.

Organisations can use data science to:

  • help improve their services and products
  • make their processes more efficient
  • discover new insights that improve their customer experience.

How we can use data science at Social Care Wales

Data science helps us analyse and use data more effectively. We can use the data we collect to improve our work through things like:

  • informed decision making - data science gives us tools to handle large datasets from social care providers more efficiently. Using data scientists to process and analyse data can also make it easier for us to make informed decisions and make the best use of our resources.
  • proactive planning and risk management - we can use data science to be proactive in managing risks, by using predictive analytics to forecast future trends or to make sure potential issues are identified early.
  • automation and efficiency - data scientists can automate repetitive tasks and processes to free up time to focus on other tasks of higher value. This increases efficiency and improves accuracy and consistency.
  • continuous improvement - data science can be used to drive continuous improvement in the sector through regular evaluations and analysis of performance data. This will identify possible areas for improvement and help us refine our strategies.


In a rapidly changing world, data science can help us make sure we achieve the best possible results for the people we work with. Moving from data analysis to data science will allow us to work with the greater volume and complexity of data now collected in health and care.

For this change to happen, we need to share information with people to help them understand how we use their health and care data. We also need to develop data science skills in social care and make sure data scientists can work with big data safely and securely.

We’re only just beginning to understand some of the opportunities that new disciplines like data science provide. They have the potential to find new insight that has previously been locked away in our data.

These new insights might improve our understanding of what we do and help us do things better in the future.
