The climate of Malta is typically Mediterranean, with hot, dry summers, warm and sporadically wet autumns, and short, cool winters with adequate rainfall. More than three-fourths of the total annual rainfall of about 22 inches (550 mm) falls between October and March; June, July, and August are normally quite dry.

The temperature is very stable, with the annual mean in the mid-60s F (about 19 °C) and monthly averages ranging from the mid-50s F (about 12 °C) to the mid-80s F (about 29 °C). Winds can be strong and frequent; the most prevalent are the cool northwesterly (the majjistral), the dry northeasterly (the grigal), and the hot and humid southeasterly (the xlokk, or sirocco). The relative humidity rarely falls below 40 percent.

Plant and animal life

Malta’s flora and fauna are typical of the low-lying coastal regions of the Mediterranean. Excessive exploitation of the forests for timber and the clearance of land for construction and agriculture have destroyed much of Malta’s woodlands, though a few stands of holm oak remain. Aleppo pine has been successfully reintroduced. Maquis, a scrubby underbrush, is found along valleys and below escarpments and consists of lentisk, carob, olive, bay laurel, and in some places the sandarac gum tree (Malta’s national tree). Garigue, a low-growing Mediterranean scrub, is the most common vegetation in Malta and covers much of the country’s limestone plateau. The steppe in Malta is dominated by various grasses, thistles, and leguminous and bulbous plants. Reed beds occur wherever there is abundant freshwater, and club mosses, sedges and grasses are found in wetlands. Glassworts, rushes, and seablites are native to the salt marshlands. Sand couch, sea kale, and sea daffodils are found on Malta’s few remaining coastal dunes, while golden samphire, rock samphire, and sea lavenders (several of which are endemic) are characteristic of low-lying rocky coasts. Cliffs and coastal screes support many of Malta’s native species, which include monotypic genera such as the Maltese cliff-orache (Cremnophyton lanfrancoi) and the Maltese rock-centaury (Palaeocyanus crassifolius), the latter of which is the national plant.

The native mammals in Malta include a subspecies of the Sicilian shrew and several types of bats. Most of the country’s other mammals, including the Algerian hedgehog, Mediterranean chameleon, Etruscan shrew, rabbit, and weasel, have been introduced. Native reptiles include the Maltese wall lizard, the ocellated skink, the Moorish and the Turkish gecko, the western whip snake, and the leopard snake. The only amphibian in Malta is the painted frog, a species endemic to Sicily and Malta. Invertebrates, including insects, arachnids, and snails, are abundant.

Although there are relatively few breeding birds, migrating species are plentiful. Sea birds include the storm petrel and the Mediterranean and Cory’s shearwaters. Among the most notable birds are the Spanish sparrow, which is the most common bird in Malta, and the blue rock thrush, Malta’s national bird.

Ethnic groups

Malta’s population is composed almost entirely of ethnic Maltese, the descendants of ancient Carthaginians and Phoenicians as well as of Italians and other Mediterranean peoples. Attempts to form a unifying and homogenizing Maltese ethnicity can be traced back to the late 13th century; these efforts were consolidated in the nationalistic discourses of the late 19th and early 20th centuries. Aside from the Maltese population, there are small communities of British nationals, Sindhis, Palestinians, and Greeks on the islands. Since the 1990s, influxes of more transient but no less significant groups have arrived from North Africa and the Balkans and, in the early 2000s, from countries of sub-Saharan Africa.

Language

Maltese and English are the official languages of Malta as well as official languages of the EU. Maltese resulted from the fusion of North African Arabic and a Sicilian dialect of Italian. It is the only Semitic language officially written in Latin script. English is a medium of instruction in schools. Italian was the language of church and government until 1934 and is still understood by a sizable portion of the population.

Religion

Roman Catholicism is the official religion of Malta, but there is full freedom of religious belief. More than nine-tenths of Maltese are Roman Catholic; however, only about three-fifths of these practice their faith. The islands are an independent province of the church, with an archdiocese in Malta and a diocese in Gozo. Very small numbers of Maltese are adherents of other Christian denominations or of Islam.

There are Roman Catholic cathedrals at Mdina and Valletta, an Anglican cathedral at Valletta, and a mosque at Corradino Heights.

Settlement patterns

During the 16th and 17th centuries, under the rule of the Knights of Malta (Hospitallers), the country evolved as a maritime power, and, by the late 17th century, Valletta and other towns were thriving maritime centres. By the mid-19th century the Maltese lived mainly in the relative seclusion of clustered villages and hamlets; the fragmentation of farm holdings accentuated the individuality of the farming community. The zuntier, a parvis forming part of the church square, was the traditional focus of village life.

During the British occupation of Malta (1800–1964), the growth of the dockyard complex resulted in the ongoing development of new settlements around Grand Harbour. In the 20th century the Sliema region, just north of Marsamextt Harbour, became the most fashionable part of Malta and by the early 21st century had become a commercial and tourist centre. Following the country’s independence in 1964, the advent of industrial estates located near major villages somewhat increased urbanization, but higher living standards have given rise to residential developments all over Malta island; its central areas are now densely populated. Overbuilding has been a cause for serious concern, spawning legislation meant to protect the environment. About 95 percent of Malta’s population is concentrated in urban areas.

The essentially rural character of Gozo’s many hilltop settlements has been largely preserved in the new housing that has rapidly increased there since the 1990s. Victoria, in the south-central part of the island, is the administrative and commercial centre of Gozo. More rural still is Comino, which is mostly inhabited by tourists.

Demographic trends

Malta has one of the highest population densities in the world, though the increase in the country’s population has somewhat leveled off since the mid-20th century, with a considerable decline in the birth rate. At the same time, the death rate has remained fairly stable, having fallen only slightly, while the infant mortality rate has dropped significantly. About one-third of the population is under 30.

Following World War II, mass emigration was encouraged and even financed by the government because of high unemployment on the islands. From 1945 until the mid-1970s about 150,000 people left Malta and Gozo and settled in other English-speaking countries (the United States, the United Kingdom, Canada, and Australia). By the 1990s, however, emigration had tapered off, and many Maltese expatriates began returning to their homeland.
