Public Health in the Industrial Revolution

The Industrial Revolution (c1750--1900) transformed Britain from a rural, agricultural society into an urban, industrial one. Rapid urbanisation led to appalling living conditions in the new industrial towns and cities, creating a public health crisis that forced the government to intervene.

The Growth of Industrial Towns

Between 1750 and 1900, Britain's population grew from around 6 million to over 30 million. People migrated in huge numbers from the countryside to towns and cities in search of work in factories and mills.

City	Population in 1801	Population in 1851
London	1,117,000	2,685,000
Manchester	75,000	303,000
Birmingham	71,000	233,000
Leeds	53,000	172,000
Liverpool	82,000	376,000

Living Conditions in Industrial Towns

The rapid growth of towns meant that housing, sanitation, and water supply could not keep up with demand.

Problem	Detail
Overcrowding	Families of ten or more crammed into single rooms in poorly built back-to-back houses
No sewage system	Human waste was thrown into streets, cesspits, or rivers
Contaminated water	Drinking water was often drawn from rivers polluted with sewage and industrial waste
No refuse collection	Rotting rubbish piled up in streets and courtyards
Pollution	Factory smoke filled the air; chemical waste contaminated waterways
Poor diet	Food was often adulterated (e.g. chalk added to bread, water added to milk)

Key Term: Back-to-back houses --- cheaply built terraced houses sharing three walls, with no rear ventilation or yard. They were damp, dark, and prone to disease.

Disease in Industrial Towns

The filthy conditions provided the perfect breeding ground for epidemic diseases.

Disease	How It Spread	Key Outbreaks
Cholera	Contaminated water	1831--32, 1848--49, 1853--54, 1866
Typhus	Lice and fleas in overcrowded conditions	Endemic in slum areas
Typhoid	Contaminated water and food	Widespread throughout the 19th century
Tuberculosis (TB)	Airborne droplets in crowded housing	The biggest killer of the 19th century
Smallpox	Airborne droplets and contact	Periodic outbreaks despite vaccination

Key Figures in Public Health Reform

Edwin Chadwick (1800--1890)

Chadwick was a civil servant who investigated the link between poverty, living conditions, and disease.

Achievement	Detail
Report on the Sanitary Conditions of the Labouring Population (1842)	Showed that the average life expectancy of a labourer in Manchester was just 17, compared to 38 in rural areas
Argued for reform	Proposed clean water supplies, proper drainage, and the appointment of medical officers of health
Public Health Act 1848	Chadwick's report led to this act, which created a Central Board of Health and allowed (but did not compel) towns to set up local boards of health

Exam Tip: Chadwick's report is a key turning point. However, the 1848 Public Health Act was permissive, not compulsory --- most towns ignored it. This is an important distinction that examiners look for.

John Snow (1813--1858)

Snow was a London doctor who investigated the 1854 cholera outbreak in Soho.

Achievement	Detail
Broad Street pump investigation	Mapped cholera deaths and traced them to a single water pump on Broad Street
Proved the waterborne theory	Showed that cholera was spread by contaminated water, not miasma
Removed the pump handle	Persuaded the local council to remove the pump handle; the outbreak subsided
Limitations	He could not explain how water caused cholera (germ theory had not yet been developed); many people remained sceptical

Key Legislation

Date	Legislation	Key Provisions
1848	Public Health Act	Created a Central Board of Health; allowed (not required) towns to set up local boards
1866	Sanitary Act	Required local authorities to provide sewers, clean water, and street cleaning
1875	Public Health Act	Made it compulsory for local authorities to provide clean water, proper drainage, sewage systems, and to appoint medical officers of health
1875	Artisans' Dwellings Act	Gave local authorities power to demolish slum housing and build better homes

The Great Stink of 1858

In the hot summer of 1858, the smell from the polluted River Thames became so unbearable that Parliament could not sit. This event, known as the Great Stink, finally convinced the government to invest in London's sewage system.

• Joseph Bazalgette was commissioned to design and build a vast underground sewer network for London.
• Over 1,300 miles of sewers were constructed between 1859 and 1875.
• Sewage was redirected away from central London to treatment works downstream.

Exam Tip: The Great Stink is an excellent example of how a single dramatic event can accelerate government action. However, note that the government acted because MPs were personally affected --- not necessarily out of concern for the poor.
