As one of South America’s larger capital cities, Lima, Peru, is remarkably understudied as a demographic and economic entity unto itself. In this important book, Henry Dietz presents an in-depth historical, sociological, and political analysis of a major Latin American city in the post–World War II period. Dietz examines electoral data for Lima’s districts from six censuses conducted between 1940 and 2007, framed against a backdrop of extensive demographic data for the city, to trace the impact of economic collapse and extended insurgency on Lima and its voters.
