“Strategically important, Gibraltar was reluctantly ceded to Great Britain by Spain in the 1713 Treaty of Utrecht; the British garrison was formally declared a colony in 1830. In a referendum held in 1967, Gibraltarians voted overwhelmingly to remain a British dependency. The subsequent granting of autonomy in 1969 by the UK led to Spain closing the border and severing all communication links. Between 1997 and 2002, the UK and Spain held a series of talks on establishing temporary joint sovereignty over Gibraltar. In response to these talks, the Gibraltar Government called a referendum in late 2002 in which the majority of citizens voted overwhelmingly against any sharing of sovereignty with Spain. Since late 2004, Spain, the UK, and Gibraltar have held tripartite talks with the aim of cooperatively resolving problems that affect the local population, and work continues on cooperation agreements in areas such as taxation and financial services; communications and maritime security; policy, legal and customs services; environmental protection; and education and visa services. Throughout 2009, a dispute over Gibraltar's claim to territorial waters extending out three miles gave rise to periodic non-violent maritime confrontations between Spanish and UK naval patrols. A new noncolonial constitution came into effect in 2007, and the European Court of First Instance recognized Gibraltar's right to regulate its own tax regime in December 2008. The UK retains responsibility for defense, foreign relations, internal security, and financial stability.”
CIA's The World Factbook (2013)5
In the UK's 2016 referendum on membership of the EU, Gibraltar voted overwhelmingly to Remain in the EU; only 4% voted to leave, with an impressive turnout of 84%. Almost every aspect of Gibraltar's economy, social structure and daily working relies heavily on smooth access to EU markets and labour.
As a territory of the UK I do not have many specific statistics for this territory in its own right.
Data from the Pew Forum, a professional polling outfit, states that in 2010 the religious makeup of this country was as follows in the table below6:
The CIA World Factbook has slightly different data, and states: Roman Catholic 78.1%, Church of England 7%, other Christian 3.2%, Muslim 4%, Jewish 2.1%, Hindu 1.8%, other or unspecified 0.9%, none 2.9% (2001 census)7.
There isn't much information in the database for Gibraltar, most likely because it is either a part of another country (i.e., a territory or possession) and therefore most international statistics are counted for the country as a whole, or, this is such an exotic place that little data exists about it.
