Geographers divide economic activity into four sectors. Understanding these is fundamental to explaining what happened to the UK — and why it mattered to real communities.
Mining coal and iron ore, fishing, farming, quarrying. In the 19th century, coal mining employed over 1 million people in Britain. Today, fewer than a thousand. The mines that powered the Industrial Revolution are almost entirely closed. Primary employment in the UK has fallen from roughly 25% of the workforce in 1900 to under 2% today.
Taking raw materials and making things: steel, ships, textiles, cars, machinery. This was the UK's dominant sector through most of the 20th century. Manufacturing employed around 8 million people in the UK in 1970. By 2020, that figure had dropped to approximately 2.5 million — a loss of 5.5 million manufacturing jobs in fifty years.
Providing services rather than goods: banking, retail, healthcare, education, hospitality, law, accounting. This is now the dominant part of the UK economy by far, accounting for approximately 80% of GDP and employing around 85% of workers. The shift from secondary to tertiary is called deindustrialisation.
The newest and most highly valued sector: research, technology development, data analysis, pharmaceuticals, software, biotechnology. This is where the highest-paid and most skilled jobs now exist. Cambridge Science Park, where over 120 companies develop new medicines and technologies, is a classic example. So is the "Silicon Roundabout" tech cluster around Old Street in London.
The UK's economic history over the past 50 years is essentially the story of a country moving from the bottom of that list to the top — from digging coal to developing algorithms. But that transition was not painless, not fast, and not equally distributed.
