Kennedy's next two chapters depend greatly upon Bairoch's calculations of industrialization, measuring all nations by an index, where 100 is the British per capita industrialization rate in 1900. The United Kingdom grows from 10 in 1750, to 16 in 1800, 25 in 1830, 64 in 1860, 87 in 1880, to 100 in 1900 (page 149). In contrast, France's per capita industrialization was 9 in 1750, 9 in 1800, 12 in 1830, 20 in 1860, 28 in 1880, and 39 in 1900. Relative shares of world manufacturing output (also first appearing on page 149) are used to estimate the peaks and troughs of power for major states. China, for example, begins with 32.8% of global manufacturing in 1750 and plummets after the First Opium War, Second Opium War and Taiping Rebellion to 19.7% of global manufacturing in 1860, and 12.5% in 1880 (compared to the UK's 1.9% in 1750, growing to 19.9% in 1860, and 22.9% in 1880).
