Industrial Revolution Living Conditions: Urban Crowding, Sanitation, and Health Impacts

The Industrial Revolution (1760–1840) drove unprecedented urbanization, creating squalid living conditions that became a public health crisis.

Housing

• Back-to-Back Terraces: No rear windows/ventilation; shared walls.
• Cellar Dwellings: Damp, dark, flooded – poorest families.
• Overcrowding: Multiple families per house; 10–20 people in 2 rooms. Lodgers common.
• No Building Codes: Jeremiah's "courts" – narrow, sunless alleys.

Sanitation & Water

• No Sewers: Cesspits, open gutters, "night soil" men. Contaminated wells (Broad Street pump – Snow's cholera).
• Water Supply: Intermittent, polluted. Private companies, no regulation.
• Waste: Horse manure (1,000s tons/day in London), industrial effluent, human waste in streets.

Pollution

• Air: Coal smoke (domestic + industrial) → "pea-souper" smogs, soot, SO₂. Respiratory disease rampant.
• Water: Rivers (Thames, Irwell) = open sewers. "Great Stink" 1858.
• Noise: Machinery, crowded streets.

Health Consequences

• Infectious Disease: Cholera (1831, 1848, 1854), typhoid, typhus, TB (consumption – 1/4 deaths), smallpox, diarrheal diseases.
• Mortality: Urban death rates > rural. Manchester 1840: 32/1000 vs national 22. Life expectancy: Liverpool laborer 17 yrs; gentry 35.
• Child Mortality: >50% died before 5 in industrial cities.
• Occupational Disease: Byssinosis (cotton), silicosis, lead poisoning, phosphorus necrosis (phossy jaw).

Reform Movements

• Edwin Chadwick – Sanitary Report (1842) → Public Health Act 1848.
• John Snow – cholera epidemiology.
• Joseph Bazalgette – London sewer system (1860s).
• Factory Acts (1833 onward) – child labor, hours, safety.
• Model housing (Saltaire, Bournville, Port Sunlight).

These conditions birthed modern epidemiology, public health infrastructure, and labor movements.
