This case study demonstrates the variability of urban patterns. Greater London is divided into 32 boroughs. Urban disparities are stark and clear 57 per cent of children in the inner London borough of Tower Hamlets live in poverty - a greater proportion than in any other borough in England. The City of Westminster has the nation's highest level of childhood obesity, while Southwark has one of the highest rates of teenage pregnancy nationwide. In contrast, the outer London borough of Richmond upon Thames shows good levels of child health and well-being, and London children overall seem to have above-average dental health.
