Salisbury today

A cathedral city in a large rural county

Census 2021 figures for the Wiltshire unitary authority and for the middle-layer areas of Salisbury named by the House of Commons Library, from the Office for National Statistics on Nomis.

Wiltshire and seven Salisbury areas, Census 2021, usual residents
Area	Usual residents
Wiltshire	510,333
Salisbury Bishopsdown	6,868
Salisbury Bemerton	7,623
Salisbury Stratford	5,889
Salisbury Churchfields	6,905
Salisbury Town North and Milford	6,156
Salisbury Cathedral and Harnham	5,038
Salisbury East Harnham	6,048

Older than average

Across Wiltshire, people aged 70 to 74 were 5.9% of residents in 2021, above England's 5.0%, while those aged 20 to 24 were 4.7%, against 6.0%.

In education

Of Wiltshire's 484,705 residents aged five and over, 84,967 were students, 17.5%, a little below the national 20.4%.

Around the Close

The area named Salisbury Cathedral and Harnham had 5,038 residents at 2,464.8 people per square kilometre, far denser than the county's 156.8.

Our Salisbury classes bring together learners from all over the city. A Year 2 child in Bishopsdown might be making a first animation, a Year 11 student in Bemerton preparing GCSE Computer Science, and an adult in Laverstock learning Python for work, each placed in a small group at the right level.

Magna Carta

A charter carried to Old Sarum

From Salisbury Cathedral's own Magna Carta page, the charter's text, and Historic England's open data.

15 June 1215

Salisbury Cathedral says King John agreed Magna Carta on this day to make peace with a group of barons and church leaders. The charter itself lists "William, earl of Salisbury" among those on whose advice the king acted.

Old Sarum

The cathedral's copy was delivered to the first Salisbury Cathedral at Old Sarum, probably by Elias Dereham. Historic England schedules Old Sarum as an ancient monument.

From 1220

Elias Dereham later became a priest at Salisbury and oversaw the building of the present cathedral from 1220 onwards. Historic England lists the Cathedral Church of St Mary at Grade I.

The cathedral names the other surviving 1215 originals as those held by the British Library and Lincoln Castle. We have no connection with Salisbury Cathedral, Wiltshire Council, the Avalon Project or Historic England. Magna Carta belongs on this page because it is a real document with 63 clauses, famous phrases and more than one English translation, which is exactly what makes searching it interesting.

Where the text comes from

The Avalon Project at Yale Law School publishes an English translation of the 1215 Magna Carta online, clause by clause. The original is in Latin; every English version is someone's translation, and translations differ.

Signature project

Can you find a sentence without reading every letter?

Rabin-Karp search turns each stretch of text the length of the target into a number, and only compares letters when the numbers match. The trick is updating that number as the window slides, instead of starting again.

Searching the Avalon translation of Magna Carta 1215 (27,150 characters) for Clause 40 as Avalon words it (75 characters)
Method	Work done	Result
Check every position letter by letter	29,146 character comparisons	Found at character 13,980
Hash every window from scratch	2,030,700 character operations	Found, but slowly
Rolling hash (Rabin-Karp)	54,225 character operations, then 75 checked	Found, one hash match
Exact search for the cathedral's wording	Same work	Not found: different translation

1. Clean the text

Take the preamble, the 63 clauses and the closing from the Avalon page, lower-case everything and collapse spaces, leaving 4,871 words and 27,150 characters.

2. Roll the hash

Treat the 75-character window as a number in base 256. To slide it, remove the leftmost letter's share, multiply by 256 and add the new letter. Each slide is a handful of sums.

3. Check before you believe

Two different strings can share a hash, so every match is confirmed letter by letter. Here the one match was real: the 75 letters at position 13,980 are Clause 40.

Same clause, different words

Salisbury Cathedral quotes Clause 40 as "To no one will we sell, to no one deny or delay right or justice". The Avalon translation reads "To no one will we sell, to no one will we refuse or delay, right or justice". Exact search, however fast, finds nothing. Break both into overlapping three-word pieces, called shingles, and 9 of the 12 match; with two-word pieces the overlap is 0.71, with four-word pieces 0.50. Fast exact matching and forgiving fuzzy matching answer different questions.

Shingles also show what the charter repeats. Of 4,726 different five-word phrases, 128 occur more than once. The most repeated is "the five and twenty barons", four times, followed by "the law of the land" and "lawful judgment of his peers", three times each, both phrases from Clause 39.

Searching text

Five questions before searching any document

Learned on Magna Carta, then used in search boxes, plagiarism checkers, DNA matching, spam filters and tools that spot copied code.

Choices behind a text search
Question	For Magna Carta	What goes wrong if you skip it
Which version of the text?	The Avalon English translation, named	Searching one translation for another's words
Exact or approximate?	Exact for Clause 40, shingles for comparison	A near-match reported as no match
What counts as the same letter?	Lower case, spaces collapsed	Capitals and line breaks hiding real matches
Is every hash match checked?	Yes, letter by letter	A false match reported as found
How long a shingle?	Three words, with two and four for comparison	An overlap score that depends on an unstated choice

The last row is a real judgement. Short shingles make almost any two texts look alike; long ones miss sentences with a single word changed. Reporting the scores at more than one length, as the callout does, lets a reader see how much the choice matters.

Younger learners

Hunting for a word in a page by sliding a paper window along each line, and counting how many letters they check.

Teenagers

Naive search and Rabin-Karp in Python on the full charter, then shingles to compare two translations of the same clause.

Adults

Searching and comparing documents at work, with the version, matching rules and thresholds stated alongside every result.

We are not connected with Salisbury Cathedral, the Avalon Project, Wiltshire Council or Historic England. The translation is published online and the census and listing data are open; the searches, counts and overlap scores on this page are our own work.

Coding and AI

AI can quote any document. Why should a Salisbury teenager search Magna Carta by hand?

Because quoting is only trustworthy when you can check the quote against a named text.

AI tools often produce quotations that sound right but come from a different translation, or from no text at all. A learner who has seen Clause 40 fail an exact search because two translations differ by a few words knows to ask which version a quote comes from, and knows how to check it in seconds.

Shingles are also how many systems spot copied or near-copied text, including checks for AI-generated content and duplicated training data. Building the idea on a famous 1215 document, with numbers a learner can verify, makes a powerful technique feel simple.

So a Salisbury teenager should keep learning to code in 2026, in the city that keeps a 1215 Magna Carta: machines can search millions of pages, but someone has to know which words they are really looking for. The longer argument is in why coding is worth learning in 2026.

Delivery

Harnham, Stratford or Wilton, and nowhere to travel

Salisbury sits at the centre of a wide rural area. Online, a learner in a Wiltshire village is exactly as close to the lesson as one beside the Close.

City and villages together

A learner in Churchfields and another in Wilton can take the same class with no drive into the city centre.

English school stages

Lessons follow the stages Wiltshire schools use, from Reception and Key Stages 1 to 4 to GCSE and A level, taught in English.

A real first lesson

The free session is a proper lesson on a real task, ending with a suggested level, course and weekly slot. No card is asked for.

Classes by stage

Five to ten learners at one level, from Salisbury, the rest of the UK and abroad, so every stage has workable times.

Twice a week

Two regular lessons each week, about eight a month, with holidays and exam weeks agreed with the teacher in advance.

After school here, evening there

A 4 pm lesson in Salisbury begins at 8.30 pm in India in British Summer Time and 9.30 pm in winter, as India keeps a single time all year; our teachers work evenings for UK learners.

Across south Wiltshire and beyond

Families in Amesbury, Warminster, Andover or Romsey join exactly the same classes, since every group is online and set by level.

Fees

Salisbury lesson fees

A free lesson to begin, then one fee each month.

First classUSD 0

A complete lesson free of charge, ending with advice on level, course and a weekly time.

Group tuitionUSD 100

About eight live lessons a month in a group of five to ten learners at one stage.

Private tuitionUSD 150

About eight live lessons a month, with your learner having the teacher to themselves.

A family in Milford or Churchfields pays in US dollars, like every family outside India, and there are no pound prices anywhere on our site. The free lesson always comes first, and charges start only when the course and weekly time are agreed; the pricing page covers pausing, missed lessons and moving between group and private teaching.

FAQ

Salisbury coding class questions

What Salisbury families most often ask.

How many people live in and around Salisbury?

Census 2021 counted 510,333 usual residents in Wiltshire, the council area that includes Salisbury, 498,138 of them living in households. The city's middle-layer areas range from 5,038 residents in Salisbury Cathedral and Harnham to 7,623 in Salisbury Bemerton.

How does Wiltshire compare with England?

It is rural and older than average: 156.8 residents per square kilometre against 433.5, and 5.9% of residents aged 70 to 74 against 5.0%. People aged 20 to 24 were 4.7%, below England's 6.0%.

What is Rabin-Karp search?

A way of finding a piece of text by giving each window of the same length a number, a hash, and updating that number as the window slides one letter along. Letters are compared only when the numbers match, and every match is checked.

Why did the cathedral's quotation of Clause 40 not match?

Because it comes from a different English translation. Salisbury Cathedral quotes "to no one deny or delay right or justice"; the Avalon Project translation says "to no one will we refuse or delay, right or justice". Exact search finds nothing, but 9 of the 12 three-word pieces are shared.

Where does the text come from?

From the Avalon Project at Yale Law School, which publishes an English translation of the 1215 Magna Carta clause by clause. We lower-cased it and collapsed the spacing before searching.

Why does Salisbury have a Magna Carta?

Salisbury Cathedral says its copy is one of only four surviving originals from 1215 and was delivered to the first cathedral at Old Sarum, probably by Elias Dereham. We are not connected with the cathedral.

When are Salisbury lessons held?

On weekday afternoons, weekday evenings or at weekends, at a UK time chosen together in the free lesson. India runs four and a half hours ahead of Salisbury in summer and five and a half hours ahead in winter.

Do you have premises in Salisbury?

No. There is no Salisbury centre and we have no UK premises, because every lesson is live online. A learner needs a computer with sound and a steady connection, and our phone number is Indian.

How much are lessons for a Salisbury learner?

The first lesson is free. After that, a group place is USD 100 a month for two live lessons a week, about eight a month, with five to ten learners; one-to-one teaching on the same pattern is USD 150 a month. Nothing is charged until the course, format and time are agreed.

How are learners matched into groups?

By level, pace and goals rather than age or location, with five to ten learners at the same stage. If no group fits the learner's week, we offer one-to-one lessons.
