The Cambridge Corporate Database & Regional Growth


This project concerns the modelling of the growth of businesses in the local region and providing the data for Cambridge Cluster Insights. It also involves feeding the results into a regional spatial forecasting model used by researchers at the Department of Architecture at the University of Cambridge to study infrastructure constraints and solutions for the regional economy. The various elements of the project are described below. 

Cambridge growth analysis

Cambridge Cluster Insights

Since the project group’s formation, we have been concerned with establishing an authoritative analysis of the current scale, make-up and growth rate of economic activity in the Cambridge city region, defined by a 20 mile radius around Cambridge. We were commissioned by Cambridge Ahead to create a dashboard to monitor growth in Cambridge using the original Cluster Map created by Sherry Coutu and Trampoline Systems as a starting point. We began by updating and re-verifying the original Cluster Map data, adding data from sectors outside of high tech and extending the coverage to all companies, however small; and then putting in place curation to keep it up to date. For the first time, there is now a sound and robust measure of the Cambridge economy, and how it is growing, but it is also possible to wind the clock backwards to see how Cambridge has been growing in the past. 

The Cambridge Cluster Insights platform, known initially as Cambridge Cluster Map, was officially launched in July 2016 and is a dataset of information on over 26,000 businesses in the Cambridge city region. Using the new methodology, it specifically monitors the growth of Cambridge-based companies, in terms of their global turnover and global employment, and tracks the number of Cambridge-active companies, and public and charitable sector research organisations. 

Cambridge-based companies are those with their primary trading address within this area, or those that do not give a primary trading address but have a registered office in this area. Cambridge-active companies are those who have neither their registered office, nor primary trading address in the Cambridge area but do have a trading address in the area that we have identified, examples being Amazon, Apple and Microsoft. Non-corporate Knowledge-Intensive (KI) organisations are those research institutions that are located in the defined region which are neither companies, nor partnerships. Examples of these are the British Antarctic Survey, the MRC Laboratory of Molecular Biology and the Wellcome Sanger Institute. 

Cambridge Cluster Insights has been refreshed approximately twice a year and will be updated with wholly new data annually. The last update was published in March 2022 and captures the impact of the first year of COVID in England. A new and improved Cambridge Cluster Insights platform was launched in September 2019. This new platform, which covers eleven years of data for the Cambridge city region as well as each of the six local authority districts in the Cambridgeshire and Peterborough Combined Authority area, allows for a dynamic, interactive and timely analysis of the business population in the local region.

The work underpinning Cambridge Cluster Insights is disseminated locally, nationally and internationally. For example, our approach and key findings were presented at a series of workshops and seminars organised by a number of research institutions in China, including Liaoning University, Shenyang Institute of Technology, Shenyang University and Communication University of China.

Growth data

Using unique growth measurement methodology, the project has so far produced seven consecutive sets of growth data for the Cambridge city region; in February 2016, January 2017, May 2018, April 2019, March 2020, March 2021 and most recently in March 2022. 

The last set of data shows that corporate growth in the Cambridge city region has been robust over the past decade, but fell from 4.0% in 2019-20 to 1.8% in 2020-21. The latter is still a significant rate of growth considering the scale of the challenges brought about by the COVID pandemic. The slowdown in employment growth over the past three years is due to a weaker performance amongst non-KI sectors. Overall, KI companies have maintained a high rate of employment growth, which has offset the decline in employment amongst non- KI companies. Information technology and life sciences are the largest and most dynamic of these KI sectors, with a strong performance also through the first year of the pandemic. The UK Government’s furlough scheme has reduced the impact of COVID on employment over this period. This is, in part, reflected by the relatively worse performance of turnover over the past year (0.7% growth against a figure of 1.8% for employment). 

The number of people employed in universities and non-corporate research institutions in the area (37,000 employees) has also continued to grow steadily, making the area one of the largest concentrations of KI employment in Europe. 

At the same time, there are signs that employment created by new business start-ups does not exceed the loss of jobs due to company closures and this imparts a small, but negative, impact on growth. There are also signs of companies moving out of Cambridge, possibly in response to the rising cost of doing business in the city. 

Overall, these figures demonstrate not only the importance of Cambridge to its wider region, but also the value it offers on a national scale as a net contributor to the UK. As cited by Centre for Cities, Cambridge was the third fastest-growing city for jobs in the country between 2004 and 2013.

The Business Board (formerly Greater Cambridge Greater Peterborough LEP)

The CBR was commissioned to create a company database for the 14 local authority districts making up the Greater Cambridge Greater Peterborough (GCGP) Local Enterprise Partnership (LEP, now The Business Board). This work has been completed and the database includes 83,000 LEP-based companies and limited partnerships with their employment and turnover over the last decade. Of these, about 52,000 were alive at the end of the 2020-21 financial year and together represented employment of 502,000 and turnover of £87.7 billion. The analyses carried out examine the sectoral composition and growth of each of the local authority districts. Data for the eight LEP districts outside the Cambridgeshire and Peterborough Combined Authority area are provided on Cambridge Cluster Insights only up to 2017-18. 

Greater Cambridge employment updates

CBR research is currently helping local councils and other authorities in the local region to provide support to businesses during the COVID-19 pandemic. This research comprises a series of updates, commissioned by the Greater Cambridge Partnership and Cambridge Ahead, which bring up-to-date information about what is happening to corporate employment in the Greater Cambridge area that would not otherwise be available. It provides policymakers with robust and timely data on businesses and sectors in the area that can guide COVID recovery strategies and future investment plans. 

Our latest update was completed in October 2021 and captures the effects of the first and second COVID lockdowns in England. The picture is one of continued but lower employment growth in Greater Cambridge during the last year. The slowdown in employment growth was due to a weaker performance of non-KI sectors, whilst employment growth in KI sectors remained unchanged. The impact of COVID-related restrictions on Greater Cambridge corporate employment was mitigated by the life science and information technology sectors, which have seen employment growth accelerate in the latest year despite the unfolding of the pandemic. Our analysis also reveals that turnover suffered larger falls than employment, pointing to the benefits of the furlough scheme in protecting employment in sectors with declining sales. 

Economic forecasting

We are working with the local authorities to take their current economic model input data and add local understanding to it by using local business and sector-specific expectations rather than national ones. We are seeking to discover what businesses think future growth pressures will be, and what their growth might be if those pressures were better managed, in order to prioritise the infrastructure initiatives that will need to be taken. Creating such a bottom-up regional growth forecast has never been attempted before, and we have a great learning curve to get round to do it, but it should be very powerful when completed. 

For example Cambridge has, with Marshall and its supply chains, a large aerospace component in its economy so the growth expectations of the aerospace sector will feature strongly in the local forecast. Where this breaks down though is that the national forecasts will be dominated by what Rolls Royce’s and BAE’s growth expectations are, which could be very different from Marshall’s. 

A survey of the largest companies in the Cambridge area has been carried out. The survey focuses on three aspects: the connections between the Cambridge companies and the rest of the UK economy; local constraints on their growth; and their estimates of their sector’s growth over the next five years. It also asks their opinions about their impact on the economy, government policy and the impacts of Brexit on their growth. This survey allows for a bottom-up forecast of how much these companies think their sectors will grow over the next decade. In a nutshell, the survey results suggest that travel to work problems, along with the high cost and limited availability of housing, are affecting recruitment and retention of staff while impinging on productivity. These problems are also identified by companies as major factors limiting their growth in the Cambridge region. Despite these constraints, companies remain quite optimistic about their growth prospects, but are very concerned about Brexit. 

A further supplementary technical task of comparing the actual and forecast growth rates of employment from the Councils’ East of England Forecasting Model (EEFM) with CBR data is being undertaken. A similar comparison is being conducted with employment growth rates from the Business Register and Employment Survey (BRES) and other employment-related sources maintained by the ONS. 

Cambridgeshire and Peterborough Independent Economic Review

The Cambridgeshire and Peterborough economy is of national and international significance, comprising some of the fastest growing areas within the UK and internationally competitive industry, innovation and research. At the same time, it faces a number of challenges, constraints and imbalances that could hinder growth in the region if these are not properly addressed. 

The purpose of the Cambridgeshire and Peterborough Independent Economic Review (CPIER) is to create a single strategic position to help the Cambridgeshire and Peterborough area consider the case for greater fiscal devolution and powers to unlock the delivery of major infrastructure. The CPIER is led by the Cambridgeshire and Peterborough Independent Economic Commission (CPIEC) and is co-funded by the Cambridgeshire and Peterborough Combined Authority, The Business Board and Cambridge Ahead. 

Drawing on the corporate database as a unique source of information for businesses in the Cambridgeshire and Peterborough area, the CBR produced a number of analyses to support the work of the CPIEC. These include novel and in-depth studies of the corporate anatomy, foreign ownership and ownership changes, business demography and specialness of the corporate sectors in the Combined Authority and in each of its local authority districts. 

After the ground-breaking CPIER work, the growth data produced by the CBR are being used to inform the Local Industrial Strategy. Support was also provided to the Digital Sector Strategy for Cambridgeshire and Peterborough, delivered by Cambridge Wireless and Anglia Ruskin University, through the provision of a range of quantitative data and analyses. The Digital Sector Strategy was published in May 2019 and is considered a valuable contribution to the Local Industrial Strategy.

The benefits and impact of the Babraham Research Campus

We have been working with Cambridge Economic Associates, Cambridge Econometrics and Savills on a project commissioned by Babraham Bioscience Technologies Ltd and its campus partners (BBSRC and the Babraham Institute) to identify, capture and demonstrate the benefits and impact of the Babraham Research Campus. 

As part of this work, we designed and conducted a survey of Campus companies to quantify the impacts they make in local, national and international ecosystems. The survey, which achieved an extremely high response rate of 74%, also allowed to assess the scale and type of investment received by Campus companies over time. Responses from the survey were combined with unique information from the CBR corporate database to carry out detailed analyses of companies located on the Campus against those on other business and science parks in the Cambridge region. 

The outputs from the impact assessment study are being used to inform the future development of the Babraham Research Campus and the overall contribution it provides to the Cambridge and UK economy. The final report, along with an Executive Summary highlighting the key findings from the impact assessment study, was published in June 2020.
