Adoption Registration Service

Unfortunately, our service which checks for a record of a Civil Death Registration in England, Wales and the Isle of Man on behalf of adoptees and birth relatives to establish if an adoptee or birth relative is recorded as having died, is under review and is therefore not currently available. Following the review, our website will be updated.

Adult social care data hub

This hub allows you to explore a range of adult social care datasets and interactive tools.

Adult Social Care Outcomes Framework (ASCOF)

The Adult Social Care Outcomes Framework (ASCOF) measures how well care and support services achieve the outcomes that matter most to people. The measures are grouped into four domains which are typically reviewed in terms of movement over time. Data is provided at council, regional and national level.

Innovative uses of data

This service will support the planning, delivery and evaluation of health and social care. By creating tools and analytics that harness data science techniques, we can offer new insights that are easily accessed and understood.


Linked HES-ONS mortality data

Find out about linked HES-ONS mortality data. Combined data in Hospital Episode Statistics (HES) and Office of National Statistics (ONS) datasets provides additional valuable information, such as the cause of deaths and deaths outside of hospital, which is not available if only using HES.

We hold a database of population data on behalf of the Office for National Statistics (ONS) that can be used to analyse births and deaths.

Public health

The choices people make can have a lasting impact on their health. Improving patient care isn't just about treating people's individual diseases, it also means changing and preventing harmful behaviours which can improve and even save people's lives.


Quality and Outcomes Framework (QOF) online database

We have developed an online database to find the results of your local GP practice and to report the latest annual QOF points. You can also use the database to compare your local GP practice with other GP practices locally, or across England.

The Strategic Data Collection Service (SDCS) is a secure data collection system used by health and social care organisations to submit data to NHS Digital.

Supporting open data and transparency

Open data is data that can be used and shared by anyone, for any purpose. We make this data publicly available to improve transparency in health and care.
