Historical population

French Guiana experienced a long period of demographic stagnation during the days of the Cayenne and Saint-Laurent-du-Maroni penal colonies (19th century and first half of the 20th century), when, with the exception of a brief gold rush in the 1900s and 1910s, it suffered from a bad reputation due to its association with penal colonies and bad sanitary conditions (yellow fever and malaria in particular).

Population started to grow tremendously from the 1950s onwards with the improvement of sanitary conditions (yellow fever and malaria eradication campaigns started in 1949) and the establishment of the Guiana Space Centre in 1964. Population growth has been fueled both by high birth rates and large arrivals of immigrants (from metropolitan France, to man the public administrations and the space center, as well as from neighboring countries, in particular Suriname and Brazil). Arrivals of Surinamese refugees reached record levels in the 1980s during the Surinamese Interior War, resulting in the highest population growth rate in French Guiana's history, recorded between the 1982 and 1990 censuses (+5.8% per year).

In the 21st century, the birth rate has remained high, and new arrivals of migrants seeking asylum (in particular from Haiti) have kept population growth above 2% per year in the 2010s. French Guiana's population reached 295,385 in 2024 (Jan. estimate), more than 10 times the population it had in 1954.
