The British passport issued in Jersey carries no mention of the United Kingdom on its cover. Its holders are British citizens, and the island they hold it from has never been part of England or of the United Kingdom. Jersey is a self-governing British Crown Dependency of 103,267 people counted at the census of 21 March 2021, on about 118 square kilometres of granite and sand 22 kilometres off the coast of Normandy. The Crown answers for its defence, for its relations with other states and for the royal assent to its laws, and an Assembly elected on the island decides everything else, from income tax to the courts.

What the Crown keeps and what Jersey holds
No single document sets out Jersey's relationship with Britain. Policy Centre Jersey wrote in 2025 that it rests on custom and practice, and dates it to 1204 and to a run of royal charters in the fourteenth century, with nothing basic changed since. The island never sent a member to Westminster. Its allegiance runs to the monarch, who is styled Duke of Normandy in the Channel Islands, a title Henry III renounced in 1259 and the islands still use.
Jersey Finance's constitution factsheet of June 2026 lists what the Crown keeps: royal assent to the island's legislation, military defence, and the representation of Jersey's interests abroad. Everything else sits in Jersey's own legal, administrative and fiscal systems. The factsheet adds that Jersey takes no subsidy from the UK and pays it no contribution, and makes voluntary annual payments towards the cost of its defence and its international representation.
| Matter | Who answers for it |
|---|---|
| Laws | The States Assembly; royal assent through the Privy Council, then registration by the Royal Court |
| Defence | The Crown, with voluntary annual contributions from Jersey |
| Relations with other states | The UK in law; Jersey signs some treaties itself when the UK entrusts it to |
| Citizenship and passports | British nationality law; there is no Jersey citizenship |
| Taxes, courts, schools, police, health | Jersey |
| Money | The pound sterling, with Jersey's own notes and coins |
| European Union | Never a member; the Protocol 3 arrangement lapsed with Brexit |
Membership of the United Nations and the Commonwealth is open only to sovereign states, so Jersey belongs to neither. A framework the two governments agreed in 2007 records that the UK "has no democratic accountability in and for Jersey" and that the island "has an international identity which is different from that of the UK". How that division works day to day, and where it is argued over, is the subject of the article on Jersey's politics.
Why Jersey still runs on Norman institutions
William Longsword annexed Jersey to Normandy in 933, and when Duke William took England in 1066 the island reached the English crown as part of his duchy. King John lost mainland Normandy to the French king in 1204 and kept the Channel Islands. Who chose that outcome is disputed: Jersey Finance writes that the islands "were persuaded to side with King John", and Policy Centre Jersey that it "was not the people of Jersey who made this decision".
The courts set up afterwards were Norman courts, with a Bailiff and twelve jurats, because the crown went on claiming the duchy and English law in the islands would have weakened the claim. A Privy Council order of 18 February 1617 gave military command to the Governor and justice and civil affairs to the Bailiff, and the Code of 1771 gave the States the sole power to make law. The Bailiff still presides over the Assembly, and a royal mace presented by Charles II is still carried in before the Bailiff at every sitting.
German forces held the island from 1 July 1940 to 9 May 1945. About 40,000 people were left on the island when they arrived, by the Government of Jersey's count, and 9 May is kept as Liberation Day. After the war the militia was abolished, and for the first time since Edward III the island had no permanent military presence. How the island's civil government conducted itself under German rule is still argued over, and Jersey: history sets out both readings.
How the tide changes the size of Jersey
The island measures roughly 14 kilometres from west to east and 8 from north to south. Its north coast is a line of pink granite cliffs and headlands. Behind them lies what Policy Centre Jersey described in 2024 as a 100-metre plateau of small fields and hedgerows, cut by steep wooded valleys that run south to wide sandy bays. Les Platons, on the north coast, reaches 136 metres.
The south-east coast is where the island grows and shrinks. A maximum spring tide range of 12 metres uncovers 17.5 square kilometres of rock platform, reef and gullies there, according to the Channel Islands Ramsar code of conduct, and Policy Centre Jersey put the gain at around 25% of the island's size in 2024. The record gives Jersey 118 square kilometres, the Wikipedia account 119.6 including reclaimed land and the intertidal zone, and some sources 120.
The mean air temperature over the 1991 to 2020 average was 12.39 °C. People settled on the low southern side, and 35% of the 2021 population lived in St Helier, the island's only town. Why the valleys drain south and what the offshore reefs add at low water belong to Jersey's landscape.
How Jersey chooses a government without parties
All 49 elected seats in the States Assembly are filled on one day every four years. The election of 7 June 2026 returned 9 Senators elected island-wide, 28 Deputies from nine constituencies and 12 Connétables, one for each parish. Reform Jersey won seven of the Deputy seats, and every other member elected stood without a party.
The Assembly then builds the government itself. Members nominate and vote on a Chief Minister, and then on each minister in turn, a system that replaced government by committees of the States in 2005. The executive, ministers and assistant ministers together, may not exceed 21 of the 49, so it can never command a majority on its own. Turnout in 2026 was 32.4%, after automatic registration had enlarged the electorate. The Bailiff's seat at the head of the chamber is one of the open arguments Jersey: politics follows.
What Jersey lives on
Statistics Jersey put the island's gross domestic product at £6,859 million in 2024, down 0.7% in real terms. Financial and insurance activities produced 38.5% of gross value added that year and employed 22.0% of the working population in December 2024, and Policy Centre Jersey estimated in 2025 that finance accounts for around 70% of tax revenue, most of it personal tax paid by the people the sector employs.
The two products that carry the island's name belong to an older economy. The Jersey cow has been kept pure by a ban on importing other breeds that dates back to 1763, and the lineage of every cow on the island has been recorded in the Herd Book since 1860. Jersey Royal potatoes are grown early on south-facing côtils, steeply sloping fields. Tourism brought more than 1,000,000 visits in 1997 and an estimated 526,500 in 2023. A fall in one banking line took the whole economy down in 2024, and Jersey: economy traces how.
Which languages Jersey speaks and keeps
English is the everyday language. At the 2001 census 113 residents named Jèrriais, the island's Norman language, as the one they mainly spoke, against 4,002 who named Portuguese; 2,874 people spoke Jèrriais at all, and two-thirds of them were 60 or over. Compulsory schooling was given only in English from 1912. The States made Jèrriais an official language of the Assembly in 2019, beside English and French, and the government's language strategy reports that a large share of the children taking Jèrriais lessons come from Polish and Portuguese families.
French keeps a ceremonial place. Members answer the roll call in French at the start of each States meeting, and the prayers are said in it. About half the population counted in 2021 was born in Jersey and 8% in continental Portugal or Madeira. The Battle of Flowers has been held every August since 1902, and Jersey: culture carries the island's calendar and its cooking.
How visitors reach Jersey from both coasts
Jersey lies 22.4 kilometres west of Normandy and 136 kilometres south of Weymouth, and the British coast sends most of its visitors. In 2024, 68% of visitors came from the United Kingdom, 17% from France and 7% from the other Channel Islands. An estimated 424,400 visits were made in the year to October 2025, 303,400 of them by air.
The island sits inside the Common Travel Area with the UK, Ireland and the other Crown Dependencies, the States subsidise air routes, and DFDS runs the ferry to St Malo. Why the nearer French coast sends the smaller share is taken up in Jersey: travel.

Common questions
Questions about Jersey
Is Jersey part of the United Kingdom?
No. Jersey is a Crown Dependency. Policy Centre Jersey wrote in 2025 that it has never been part of, or a colony of, England or the United Kingdom and has never had representation in the British Parliament. The UK answers for its defence and in international law for its external relations; the island makes its own laws and sets its own taxes.
Why is Jersey called a bailiwick?
After the Bailiff, the medieval head of the island, who is now civic head, president of the States Assembly and head of the judiciary. Policy Centre Jersey noted in 2025 that the word no longer has any legal meaning for Jersey's status.
What does the phrase States of Jersey refer to?
Three things, depending on context. Policy Centre Jersey calls it a confusing term: it is used for the island's parliament, for its government and for the island itself. Before the States of Jersey Law 2005 the States was one legal body holding both the legislature and the executive, and from July 2014 ministers adopted the name Government of Jersey for use abroad and in official correspondence.
How many people live in Jersey?
The census of 21 March 2021 counted 103,267 residents, and Statistics Jersey estimated 104,540 at the end of 2024. In 1974 the States approved measures to hold the population below 78,000 at the 1981 census, and population has been argued over in island politics ever since.
