The 19th century was a golden era for the Cap Corse, and one that featured maximum demographic and economic growth. The Year X survey (1802) listed a village population of 730, most of whom were aged between 20 and 40 years of age. Ninety years later, in 1891, the village listed nearly 1000 inhabitants. Around this time, immigration to America began, starting the "Americans" period, when Capcorsins would venture "across the seas" to make their fortunes. World War 1 accentuated this movement, and the population of Corsica, and more specifically, the village of Pietracorbara, diminished. In 1936, the village consisted of only 418 inhabitants, and by 1960, not even half that number: 230 permanent residents. In 1975, the number rose to 248; in 1990, the number of residents rose again to 365. In september 2004, according to the INSEE, 497 people reside in Pietracorbara.
