💡 Exam Tips for Public Health
🎯 Question Types for This Topic:
- "How useful is Source A for an enquiry into the problems of public health in 19th-century Britain?" (8 marks, AO4) — Evaluate using NOP (Nature, Origin, Purpose) and support or challenge with own knowledge. Level 4 needs detailed NOP analysis AND specific own knowledge: cholera epidemics (32,000 deaths 1831; 62,000 deaths 1848), miasma theory, laissez-faire ideology, Snow's Broad Street pump investigation (1854), the Great Stink (1858), and the 1848 vs 1875 Public Health Acts.
- "Explain the significance of Joseph Bazalgette's sewer network for the improvement of public health in Britain" (8 marks, AO1+AO2) — Short-term significance: 1,100 miles of sewers built under London (1858–75), ending the Great Stink and eliminating the cholera-contaminated water supply. Long-term significance: demonstrated that government-funded infrastructure could transform public health on a national scale; provided the model for compulsory action in the 1875 Public Health Act; helped shift government thinking from laissez-faire to state intervention. Show why Bazalgette's work mattered beyond London and beyond the 19th century.
- "How far did the role of the government in public health change between c.1800 and 1948?" (16 marks including SPaG) — Argue change: from laissez-faire (1848 Act permissive, councils could ignore it) to compulsion (1875 Act mandatory), then to universal welfare state (NHS 1948 free for all). Argue continuity: government always had to be pressured to act (Great Stink, Boer War, WW2); cost concerns persisted throughout. Make a supported judgement. SPaG marks: laissez-faire, compulsory, Bazalgette, cholera, Beveridge, nationalisation.
- Historic environment source question (Paper 2 Q4, 4 marks) — In some sittings, a source about the Whitechapel area of London (or the Courtauld Almshouses, or another specified historic environment) is paired with a describe-two question. Make sure you have studied the Paper 2 historic environment material for your sitting.
📈 How to Move Up Levels — This Topic Specifically:
- Level 1 (1–2 marks on explain): "Public health improved because of John Snow and the government." — This just names people and institutions with no explanation. It is a list, not an analysis.
- Level 2 (3–4 marks on explain): "John Snow investigated cholera in 1854. He found it was caused by contaminated water at the Broad Street pump." — Better: there is some specific evidence. But it still doesn't explain HOW this led to improvement in public health. What changed as a result of Snow's finding?
- Level 3 (5–6 marks on explain): "Snow's investigation of the Broad Street pump in 1854 proved cholera was waterborne, not caused by miasma as most doctors believed. This was significant because it gave reformers the scientific argument they needed to justify expensive clean water infrastructure. It directly influenced the case for the 1875 Public Health Act, which made clean water provision compulsory." — This shows the mechanism (HOW it caused improvement) and uses specific evidence. This is the level the examiner is looking for.
- Level 4 (7–8 marks on explain): Add an interconnection between factors: "However, Snow's work alone did not produce immediate government action — the real trigger was the Great Stink of 1858. This demonstrates that individual scientific discovery and political action were interdependent: Snow provided the evidence, but government only acted when the smell of the Thames made public health a matter of parliamentary self-interest rather than abstract science. The Great Stink thus converted Snow's 1854 knowledge into Bazalgette's 1858 building programme." — Complex reasoning linking multiple factors. This is what the Level 4 descriptor means by "complex explanation."
⚠️ Common Mistakes to Avoid:
- Saying Snow "proved germ theory." He proved waterborne transmission — a different thing. Germ theory came seven years later (Pasteur, 1861). Snow didn't know about germs; he knew about water. This is a very common error that marks you down.
- Treating the 1848 and 1875 Public Health Acts as the same thing. They are almost opposites: 1848 was permissive (optional), 1875 was compulsory. The difference is the entire story of how government attitudes changed over 27 years. Always specify which Act and always explain whether it was permissive or compulsory.
- Writing narrative history instead of analysis. "In 1842 Chadwick wrote a report. In 1854 Snow investigated cholera. In 1858 the Great Stink happened. In 1875 a Public Health Act was passed." — This is description, not analysis. Every event needs to be explained: WHY did it happen? HOW did it cause the next event? What factor does it represent?
- Stopping at 1875. For the 12-mark essay, if you only cover the 19th century, you will miss the Liberal reforms (1906–14) and the NHS (1948), which are essential for showing how government attitudes changed over time. The thematic study covers c.1250 to the present — include the 20th century.
- Not making a judgement in the 12-mark essay. The question says "how far do you agree?" — you MUST give a clear answer. "John Snow was the most important individual because his work created the scientific foundation without which the 1875 Act would have lacked justification" is a judgement. "There were many factors" is not.
Quick Check: What was the key difference between the 1848 Public Health Act and the 1875 Public Health Act — and why does this difference matter for the exam?
The 1848 Act was permissive — local councils were allowed but not required to create Boards of Health and improve sanitation. Most chose not to because it was expensive. The 1875 Act was compulsory — all local authorities were legally required to provide clean water, sewage disposal, and enforce housing standards. This difference matters because it shows the shift in government thinking over 27 years: from laissez-faire (individuals should take responsibility) to state intervention (government must protect citizens' health). For the exam: always specify which Act and always say whether it was permissive or compulsory — the contrast is a favourite AQA mark point.
Quick Check: Explain how the Great Stink of 1858 was more important in improving public health than John Snow's 1854 investigation. Use specific evidence in your answer.
Snow's 1854 investigation proved cholera was waterborne by mapping 500 deaths around the Broad Street pump — but this did not lead to any major legislation or infrastructure programme. Four years later, nothing had changed. The Great Stink of summer 1858 forced Parliament to act: the hot weather made the Thames — London's open sewer — unbearable. MPs themselves could not work in the Houses of Parliament. Within 18 days of the Stink beginning, Parliament passed a bill funding Joseph Bazalgette's sewer network. This is significant because Snow's scientific evidence alone was not sufficient to overcome laissez-faire ideology and the cost objections of property owners. The Stink worked because it created direct political self-interest — MPs were protecting themselves, not just poor Londoners. This demonstrates a pattern in public health history: evidence informs reform, but pressure and self-interest drive it. For the exam, this argument supports the case that government action (triggered by pressure events) was more important than individual scientific discovery alone.
