As of January 2025, Martinique's population was estimated at 355,459 inhabitants. With a total area of 1,128 km² (436 sq. mi.), the island has a population density of approximately 329.12 inhabitants per km². Residents of Martinique are known as Martiniquais. The official language is French, while Martinican Creole—an Afro-Caribbean language shaped by the legacy of slavery—is also widely spoken. Though distinct, Creole shares many linguistic features with French and remains a vital part of the island’s cultural identity.

The population of Martinique in numbers

According to INSEE, the infant mortality rate stood at 9.0 per 1,000 live births in 2010. Nearly 30% of the population falls within the 40 to 59 age bracket, making it the largest age group on the island.

Women make up a majority of the population, accounting for 54%, compared to 46% for men.
The origins of the Martinican people
The Martinican population is very mixed. The vast majority are descendants of former African slaves from the 17th century and European settlers. Many Martinicans also descend from Indians who arrived at the end of the slavery era. Martinique has many metropolitan arrivals from France, as well as from Europe in more recent times. Some Martinicans are also descendants of Chinese and Syrians who arrived in the early 20th century.
