Industrial Britain and public health (c.1750–c.1900)

This is the most heavily tested part of The People's Health theme on Paper 1. OCR regularly sets "explain the significance of Edwin Chadwick" or "how far did cholera change public health?" questions. The core argument is: without the crisis of cholera and the evidence of people like Chadwick and Snow, Parliament would not have acted.

The problem: rapid industrialisation

Urbanisation created catastrophic public health problems:

• Back-to-back housing with no ventilation, light or running water.
• Shared privies (one outdoor toilet for 40+ people); cesspits overflowing into water supplies.
• Life expectancy in Manchester c.1840: 28 years (vs 41 in rural areas).
• Child mortality: over 50% of children died before age 5 in slum areas.

Cholera epidemics

Cholera arrived in Britain in 1831–32, killing 31,000. Further epidemics: 1848–49 (62,000 dead), 1853–54, 1866.

Cholera was terrifying: a healthy person could be dead within hours.

Contemporaries believed it was caused by miasma — still the dominant theory. This mattered because it meant cleaning the air (not the water) was the priority.

Edwin Chadwick's Report (1842)

Edwin Chadwick (Secretary to the Poor Law Commission) published The Sanitary Conditions of the Labouring Population (1842):

• Used statistics to prove a direct link between poverty, overcrowding, poor sanitation and disease.
• Argued that disease cost the state money (poor rates, loss of productive workers).
• Recommended: clean water, sewage disposal, appointed Medical Officers of Health.
• Impact: helped create political will for the 1848 Public Health Act.

Chadwick still believed in miasma — he thought cleaner sewers would remove bad air, not realising the water supply was contaminated. Despite this, his recommendations accidentally improved water quality.

John Snow and Broad Street 1854

John Snow was a physician in Soho, London. During the 1854 cholera outbreak he:

1. Mapped cholera deaths onto a street map — almost all clustered around the Broad Street water pump.
2. Interviewed residents; confirmed that those who drank from the pump were sick; those who did not were healthy.
3. Persuaded the parish to remove the pump handle — deaths fell.

Snow proved cholera was waterborne, not airborne. This was a breakthrough in epidemiology but his findings were initially rejected by miasma believers including Chadwick.

The Great Stink (1858)

The summer of 1858 produced such an appalling stench from the Thames (still used as both water supply and sewer) that Parliament itself was affected — MPs could not work. This catalysed action:

• Joseph Bazalgette was commissioned to build a new London sewer system (1858–75) — 1,100 miles of sewers; intercepted sewage before it reached the Thames.
• Accidentally solved London's cholera problem (by cleaning the water, though Bazalgette designed it to remove miasma).

The Public Health Acts

Act	Key provisions
1848 Public Health Act	Created a General Board of Health; local boards could be established voluntarily; Chadwick was unpopular and it was largely ineffective
1875 Public Health Act	Compulsory for all councils to provide clean water, sewage disposal, remove nuisances; appointed Medical Officers of Health; much more effective

The difference: voluntary vs compulsory. The 1848 Act relied on councils acting; the 1875 Act forced them to.

Common OCR exam mistakes

1. Saying Snow proved miasma was wrong — he proved cholera was waterborne; germ theory (Pasteur 1861, Koch 1883) was needed to explain why.
2. Confusing the 1848 and 1875 Acts — 1848 voluntary; 1875 compulsory.
3. Forgetting that Chadwick believed in miasma — his recommendations happened to help clean water even though his theory was wrong.
4. Saying the Great Stink solved cholera — it solved London's specific problem; national solution required the 1875 Act.
