The climate of Barbados is generally pleasant. The temperature does not usually rise above the mid-80s F (about 30 °C) or fall below the low 70s F (about 22 °C). There are two seasons: the dry season, from early December to May, and the wet season, which lasts for the rest of the year. Average rainfall is about 60 inches (1,525 mm) annually, but, despite the small size of the island, rainfall varies, rising from the low-lying coastal areas to the high central district. Barbados lies in the southern border of the Caribbean hurricane (tropical cyclone) zone, and hurricanes have caused great devastation, notably in 1780, 1831, 1898, and 1955.

Plant and animal life

Very little of the original vegetation remains on Barbados; the pale green of cultivated sugarcane has become the characteristic colour of the landscape. Tropical trees, including poinciana, mahogany, frangipani, and cabbage palm, are widespread, and flowering shrubs adorn parks and gardens.

The few wild animals, such as monkeys, hares, and mongooses, are considered pests by farmers. Birds include doves, hummingbirds, sparrows, egrets, and yellow breasts. Marine life includes flying fish, sprats, green dolphins, kingfish, barracudas, mackerels, and parrot fish.

Ethnic groups and languages

People of African descent and of mixed African-European descent make up more than nine-tenths of the population. A small fraction of the population is of European (mainly British) descent, and there is an even smaller number of inhabitants who originated from the Indian subcontinent. There are small groups of Syrians, Lebanese, and Chinese. There is also a sizable expatriate community—primarily from the United States and Great Britain—made up of international civil servants, businesspersons, and retirees. English is the official language, and a nonstandard English called Bajan is also spoken.

Religion

The majority of the population is Christian. Anglicanism, the religious legacy of the British colonists who arrived in the 17th century, is the largest single denomination. Other churches established since the 18th century are the Methodist and the Moravian. Since the 19th century, however, significant religious diversity has developed. Pentecostal churches have large congregations, and the Seventh-day Adventist church has a significant minority of adherents. Smaller groups include Jehovah’s Witnesses, Roman Catholics, Bahaʾīs, Jews, Hindus, and Muslims.

Settlement patterns

Barbados is densely populated. More than one-third of the population is concentrated in Bridgetown and the surrounding area. Most of the farmland is owned by large landowners or corporations. As a result, “tenantries”—clusters of wooden houses locally known as chattel houses and located on the borders of the large estates—are as common as villages. They are usually owned by the occupants but stand on rented ground from which they may easily be moved for relocation to another site. Most of them have electricity and running water.

In Bridgetown’s commercial and administrative centre, multistory buildings are altering the features of the 19th-century town. Apart from Bridgetown, the largest towns or settlements are Speightstown, Oistins, and Holetown.

Demographic trends

Until the mid-20th century, Barbados had a high rate of population growth, which created problems of overpopulation. Over the second half of the 20th century and into the 21st, the rate of growth was slowed by the successful implementation of a nationwide family-planning program and by steady emigration, first to Britain and later to other parts of the Caribbean and to North America. In the same period the death and infant mortality rates declined sharply, and life expectancy rose above 70 years.
