With approximately 34,000 residents packed into just 6.7 square kilometres (2.6 square miles), Gibraltar has one of the highest population densities of any territory on Earth - roughly 5,000 people per square kilometre. But behind that headline number lies a rich story of migration, diversity, and community that stretches back centuries.
Current Population Figures
According to the 2022 Gibraltar Census, the most recent official count, the resident population was recorded at approximately 34,000. As of 2026, estimates place the figure closer to 35,000, reflecting continued modest growth. The 2012 census recorded 32,194 residents, meaning the population has grown by roughly 8-9% over the past decade. Note that some international sources (UN, Worldometer) cite figures above 40,000, but these typically use broader counting methodologies that include non-permanent residents.
In addition to the resident population, approximately 14,000 to 15,000 workers commute daily from Spain - primarily from the neighbouring town of La Linea de la Concepcion and other Campo de Gibraltar municipalities. These cross-border workers are essential to Gibraltar's economy, filling roles in hospitality, retail, construction, and financial services.
Ethnic and National Origins
Gibraltarians are a remarkably diverse people. The territory's population reflects centuries of Mediterranean migration. The largest ancestral groups include:
- British: A significant portion of the population has British ancestry, reinforced by military garrison families and civilian settlers over 300 years.
- Genoese/Italian: Italian traders, particularly from Genoa, settled in Gibraltar from the early 18th century and formed a major part of the civilian population.
- Spanish: Despite the political divide, Spanish heritage is deeply woven into Gibraltarian culture through intermarriage, proximity, and shared history.
- Maltese: Maltese migrants arrived during the 19th century, contributing to the territory's Catholic tradition.
- Portuguese: A notable Portuguese community has existed for centuries, with roots in trade and maritime connections.
- Moroccan and South Asian: Communities from Morocco, India, and Pakistan established themselves during the 20th century, often through military service or trade links.
- Jewish: Gibraltar has had a Jewish community since the 18th century, and the territory has four synagogues - a remarkable number for its size.
Population Density in Perspective
At around 5,200 people per km², Gibraltar is denser than many major cities. For comparison, London has a density of approximately 5,600 per km², while New York City averages about 10,400 per km² across all five boroughs. What makes Gibraltar's figure striking is that a significant portion of the territory - the Upper Rock Nature Reserve - is uninhabitable. The actual residential density is even higher than the headline number suggests.
Space is at a premium. Housing development is limited by geography - the Rock of Gibraltar takes up much of the peninsula. The government has pursued land reclamation projects to create additional residential and commercial space, most notably at Eastside and the Ocean Village marina development.
Age Structure and Life Expectancy
Gibraltar has an ageing population profile similar to other developed European territories. The median age is approximately 35 years. Life expectancy is high, at around 80 years for men and 85 years for women, reflecting excellent healthcare provision. The territory operates its own hospital, St Bernard's Hospital, and provides universal healthcare to residents.
Language and Identity
English is the official language and the language of government, education, and the courts. However, most Gibraltarians are bilingual in English and Spanish. The local vernacular, Llanito, is a creole-like code-switching blend of Andalusian Spanish and English with loanwords from Genoese, Maltese, Arabic, and Hebrew. It is a living symbol of Gibraltar's multicultural identity.
Religion
The majority of Gibraltarians are Roman Catholic (approximately 72%), reflecting the Genoese, Spanish, Maltese, and Portuguese heritage. The Church of England has a significant presence, and there are also established Muslim, Jewish, and Hindu communities. Gibraltar's religious diversity is visible in its landscape: the territory has a Catholic cathedral, an Anglican cathedral, a mosque, four synagogues, and a Hindu temple - all within 6.7 km².
Future Population Trends
Gibraltar's population is expected to continue growing modestly. The government's focus is on sustainable development, with new housing projects designed to accommodate growth without compromising the territory's character or natural environment. Immigration is managed through a permit system, and British and EU nationals (under post-Brexit arrangements) form the majority of new arrivals.
