Charles Booth’s pioneering poverty maps of Victorian London show a vivid colour-coded warren of streets, alleyways and slums tightly packed together. Those marked black and dark blue were classed as being “very poor”, defined by “chronic want”. The light blue ones were poor – “18s to 21s a week for a moderate family”. Pink streets housed those who were “fairly comfortable”, and those where the wealthy lived were marked in yellow.
The maps by the British social reformer are the 19th-century equivalent of the modern-day indices of deprivation, which rank every geographic area of the UK by its level of social and economic disadvantage. Comparing the two shows how much has changed in the past 150 years – but also what hasn’t. Historical slums have been cleared away and housing conditions have generally improved, but extreme poverty and extreme wealth continue to live side by side in the capital.
