The inhabitants of the department are called Corréziens.
The 1851 census recorded a population of 320,866: this remained relatively constant for the rest of the nineteenth century. During the twentieth century, however, Corrèze shared the experience of many of the country's rural departments as the population fell steadily.
Within Corrèze the nineteenth-century railway planners, influenced in part by the department's topography, endowed Brive-la-Gaillarde with good connections and a major junction from which railway lines fanned out in six different directions. The railways arrived in 1860, at an opportune moment, directly after phylloxera had destroyed the local wine industry. The new railways enabled the farms in the area surrounding Brive to specialise in fruits and vegetables which they could now transport rapidly to the larger population centres of central and southern France. Locally, the new agriculture triggered the development, in the Brive basin, of related businesses and industries such as the manufacture of jams and liquors, as well as timber/paper-based packaging businesses.
In 1900 both Brive and the prefecture, Tulle each had fewer than 20,000 inhabitants. By 2010 the population of the Brive urban area had reached nearly 90,000, while Tulle still had fewer than 20,000 registered inhabitants.
