Data Labs
Home » Initiatives we’re working on »
Our Data Labs project aims to open up government administrative data to the social sector. That way, charities, funders, government bodies and social enterprises can better understand the impact of their services on beneficiaries.
How does it work?
Charities, funders, social enterprises, public sector interventions all need to understand the impact of their work. Doing so means they can maximise the good they do, and minimise any harm.
But often, they have no way to know the long-term impact they have on people’s lives—whether their work changed the course of a person’s life in the long term.
Our Data Lab project is designed to do just that. By comparing the journeys of their beneficiaries to the journeys of those who are similar to them, a Data Lab can help organisations answer the question: did we make a difference? Recently, we have been focusing on establishing a Data Lab on employment. Learn more in our latest blog on Data Labs here.

Following the success of our work initiating the Justice Data Lab, we are now supporting the development of further Data Labs. We’re also working to increase the demand for data for impact measurement.
Our short guide sets out the key things we have learnt. This is a great tool to help you create your own data labs to provide a high quality, statistically robust evaluation service.

Justice Data Lab
The Justice Data Lab is a pioneering and award winning service run by the Ministry of Justice (MoJ) and gives organisations working with offenders access to re-offending data.
The information provided helps organisations to assess the impact of their work on reducing re-offending and also helps develop an understanding of effective rehabilitation.
The Justice Data Lab was launched as a pilot in 2013, and confirmed as a permanent service in 2015.

Justice Data Lab: FAQ update
This document responds to some of the common criticisms or concerns about the Justice Data Lab.

An update on ‘Data Labs’
Our 'Data Labs' project aims to open up government administrative data to the charity sector. Data Labs allow organisations to answer the all-important question: did we make a difference?

Justice Data Lab speech

Data, data everywhere
The increasing concern about how the public's data can and should be used is often difficult to balance with the potential benefits. Taking our Data Labs project as an example, Katie Boswell argues that, while we have a duty to ensure it is used responsibly, concerns about privacy shouldn't put us off data altogether.


Justice Data Lab goes from strength to strength
We are avid supporters of the Ministry of Justice's Justice Data Lab. The latest report, published today, marks another significant step forward in its development.

How useful is the Justice Data Lab?
December 2012 saw the ‘popping of metaphorical champagne corks’ at NPC’s offices: our call for access to government datasets on reoffending was coming to life. Over a year since the launch of the Ministry of Justice’s Justice Data Lab, now feels like a good time to reflect.

Five years of justice data labs
James Noble, our Impact Management Lead, wishes the Justice Data Lab a happy fifth birthday and sets out some of the amazing impact it has achieved in that time.

Health Data Lab
We believe there is a strong case for a Health Data Lab with support from the Department for Health. This service would improve access to NHS data for charities and other organisations who want to better understand the effect of their work on people’s health.
We supported NHS Digital (formerly HSCIC) to write a business case for a health analytical service/data lab, which would measure impact on secondary care: A&E, admissions, readmissions, lengths of stay and costs.
To date this business case has not been taken forward.
Education Data Lab
We are advocating for an analytical service in education.
We have consulted with the education sector and key stakeholders to develop the case for an Education Impact Data Lab (EIDL) service.
Since we launched this campaign, the Department for Education have asked that the Education Endowment Foundation tests the concept of an Education Data Service. This work is now underway, and has been commissioned to the Fischer Family Trust.
Employment Data Lab
We are working with ERSA and NCVO to help the Department for Work and Pensions (DWP) develop an analytical service that would support organisations to measure the impact of services on helping people to achieve employment outcomes.
We are looking for organisations to take part in a proof of concept for the service and help us develop the metrics and methodology. Get in touch if you’d like to be involved.

Freeing up health analysis: Using government data
In this paper we argue that relevant government departments should adopt a data labs model to enable charities to better understand the impact of their services on people's health.

Freeing-up education analysis: Using government data
Opening up government data to help improve educational outcomes for young people—making the case for the development of an Education Impact Data Lab (EIDL) to measure impact, based on the precedent of the Justice Data Lab.

Health Data Lab: An initiative whose time has come
NPC and 24 leading charities have written to the Secretary of State for Health, Jeremy Hunt MP, asking for his backing and for a Health Data Lab. Read more about what this means and why it would help improve the impact of services on people’s health.

Freeing-up education data: An irresistible proposition
We think an Education Impact Data Lab (EIDL) is an irresistible proposition—using an established approach to understand what works in education. Following the publication of our case for this service, here we outline the benefits for charities, schools, government and students.
