This study looks at all companies registered in the East Midlands and where their total assets are more than £9,000,000. The East Midlands is a medium size region with a population of 4.8 million in 2017, out of 66 million for the UK . The region comprises the counties of Derbyshire, Leicestershire, Lincolnshire, Northamptonshire, Nottinghamshire and Rutland. The main cities are Derby, Leicester, Lincoln, Northampton and Nottingham. The aim of this study is to provide an overview of the key movers and shakers in the East Midlands corporate sector. Only key data has been isolated, particularly the company's net worth and total assets, but also its full name, date incorporated, registered office, activities, shareholders, directors (with date of birth, occupation and nationality) and number of employees. Two indicators of size are used: net worth and total assets. These are preferable to turnover which is influenced by profit margins and whether the companies are capital or labour intensive. A short summary of the corporate sector in the East Midlands: Britain's hosiery and knitwear industry was largely based in the region, and in the 1980s it had more textile workers than any other British region. Derby was home to an important railway workshop. At its peak, Corby Steelworks was the largest in Britain. The region is the UK's eighth largest region in terms of total output. Total output (GVA), in 2016, was £100 billion (UK being £1,748 billion) while total output (GVA) per head, in 2016, was £21,185 (UK average £26,621). The total number employed, May-July 2018, was 2,278,000 out of UK total of 32,397,000 with an employment rate of 74.9% (UK being 75.5%). Manufacturing accounts for 16.7%, making it the region with the second highest proportion of manufacturing output within the UK, after Wales. There were 12,210 manufacturing businesses in the region in 2017. The region's largest manufacturing sectors are food and drink, transport equipment, rubber, plastics and non-metallic minerals. There were 294,000 manufacturing jobs in 2017 (12% of all jobs) while the public sector accounted for 15.6%. In 2016, the region had around 173,000 VAT registered businesses, mainly SMEs.
