Chichester today

A walled centre and the areas around it

Counts below are 2021 census results from the Office for National Statistics, as published on Nomis, for three middle-layer areas the House of Commons Library names College Lane and Oaklands, Central Chichester, and Stockbridge and Fishbourne, with the district and England alongside.

Chichester, Census 2021
Area	Usual residents	Students among those aged 5 and over	Residents per square kilometre
College Lane and Oaklands	12,300	24.2%	3,696.1
Central Chichester	8,907	19.1%	3,767.4
Stockbridge and Fishbourne	8,515	18.9%	496.8
Chichester district	124,068	17.5%	157.8
England	56,490,048	20.4%	433.5

Young adults

In College Lane and Oaklands, 1,362 residents were aged 20 to 24, 11.1% of its age table, and 534 people lived in communal establishments.

Inside the walls

Central Chichester is the most closely packed area, at 3,767.4 residents per square kilometre, and 4.6% of its residents were aged 85 or over.

Across the district

The wider district, reaching from Selsey to Midhurst, had 120,153 people in households and 4.1% of residents aged 85 or over, against 2.4% in England.

Every percentage here comes from its own census table, because each table is adjusted separately for privacy and their totals can differ by a few people. Our Chichester classes draw on the city and the villages close by. A Summersdale seven-year-old animating a first story, a Whyke student in Year 12 working through A level Computer Science and a Fishbourne adult learning Python to tidy up spreadsheets would each join a different group, placed by level rather than by age.

Walls, road and river

A Roman plan still traced by its walls

From the Victoria County History of Sussex, volume 3, which covers the city of Chichester and its cathedral.

Roman roots

The county history calls the walls and gates Roman in origin and sees no reason to think the line of the wall has changed since the Romano-British period, though little Roman work now shows.

Stane Street

The Roman road from London, part of Stane Street, approaches the city from the north-east and enters by the East Gate.

The Lavant as a boundary

In the 12th century the dean needed a licence to make a gate through the wall to reach his land beside the River Lavant, and the stream served as the church's boundary where there was no ditch.

The county history also records the fall of the cathedral spire in 1861, and its rebuilding by Sir Gilbert Scott on the original lines, from drawings made by Joseph Butler, architect to the fabric, in 1847 and 1848. In the middle of the city stands the Market Cross, which the history says was designed to stand in a wide open space. We have no connection with Chichester Cathedral or the Victoria County History, and the descriptions here are theirs.

On the National Heritage List

Historic England lists the Cathedral Church of the Holy Trinity and Cloisters (list entry 1354261) and the Market Cross (1026826) at Grade I, both listed on 5 July 1950, and the City Walls (1354262) at Grade I, listed on 8 October 1971. Near the river gauge, the Chapel at Graylingwell Hospital (1415725) is listed at Grade II.

Signature project

Is the Lavant flowing more often?

The Mann-Kendall test compares every year with every later year and counts how often the later one is higher, minus how often it is lower. That total, S, is large and positive when later years tend to be higher. Because it uses only order, one extreme year cannot dominate it.

River Lavant at Graylingwell: days with flow in each water year (October to September), 1982 to 2025, Environment Agency daily mean flow
What counts as a flowing day	Average, first 22 years	Average, last 22 years	Mann-Kendall S	p-value
Any flow above zero	184.3 days	218.3 days	221	0.026
More than 10 litres a second	163.3 days	178.4 days	64	0.52

1. Count the days

Download 16,561 daily mean flows from the Environment Agency and count, for each year from October to September, the days with flow. The record has three years with none at all, 1989, 1996 and 1997, with 1,003 of their 1,096 days flagged as estimated.

2. Compare every pair

For 44 years there are 946 pairs of years. Add one when the later year had more flowing days and subtract one when it had fewer. The result is S.

3. Ask about chance

Work out how big S would usually be if the years came in random order. For any flow, an S this far from zero, in either direction, happens by chance only about 2.6% of the time.

Why the answer is not simply yes

Three checks weaken the headline. Wet and dry spells carry over from one year to the next (the correlation between neighbouring years is 0.390), so shuffling the years in blocks of three is fairer, and that gives 0.040. Leaving out 2024, the year with most flow (337 days), moves p to 0.061. And 1,340 of the 8,857 flowing days carried 10 litres a second or less. Raise the bar to that level and S falls to 64, with p of 0.52: no sign of a trend at all. The rise is almost entirely in days of the barest trickle.

That matters because the way the record was kept changed over the years. In the 1980s and 1990s about two days in five are flagged as estimated by the Environment Agency; after 2010 the flags that appear are mostly unchecked instead. Days of near-zero flow are exactly where an estimate and a measurement are most likely to disagree. So the fair conclusion is that the Lavant has not clearly started flowing more often: there are more days with a trace of flow in the recent record, but not more days with real flow. Saying so plainly is part of the method.

Testing for trends

Five checks before calling a trend

Learned on the Lavant, then used for sales figures, website visits, exam entries, air quality and any number reported year after year.

Decisions behind the Lavant trend test
Question	For the Lavant	What goes wrong if you skip it
How is the measure defined?	Any flow, and above 10 litres a second	A trend that exists only under one definition
Are the years independent?	Neighbouring years correlate at 0.390, so blocks of three	Wet and dry runs mistaken for a trend
Does one year decide it?	Tested with and without 2024	A single flood year carrying the result
Did the recording change?	Estimated and unchecked flags counted by decade	A change in record-keeping read as a change in the river
Is every year complete?	1981 and 2026 left out; 2024 missing three days	Part-years counted as whole ones

The first row is the lesson that stays with learners. The same river, the same years and the same test give p of 0.026 or 0.52 depending on one decision about what counts as flowing. Before believing any trend, ask whether the answer survives a sensible change to its definition, and report both when it does not.

Younger learners

Keeping a tally of rainy days for a month, drawing the bars and deciding what counts as a rainy day before arguing about it.

Teenagers

Mann-Kendall, autocorrelation and permutation tests in Python on 45 years of Environment Agency river data.

Adults

Checking whether a reported trend at work survives a change of definition, a missing year or a change in how figures were recorded.

We have no connection with the Environment Agency, the Victoria County History, Chichester Cathedral, Historic England or Chichester District Council. The river data and census tables are published openly; the counts, trend tests and permutations on this page are our own analysis.

Data Analysis Course Data Science Course

Coding and AI

AI will happily draw a trend line. Why should a Chichester teenager learn to doubt one?

Because the most convincing chart can rest on a definition nobody questioned, and an AI tool will not question it for you.

Hand an AI assistant the Lavant record and ask whether the river is flowing more often, and it may well say yes, with a neat chart and a p-value of 0.026. Nothing in that answer would be false. It would simply leave out that the trend vanishes above 10 litres a second, because nobody asked.

A learner who has run the test both ways knows the next question to ask of any trend: what exactly was counted, did the counting change, and does the answer survive a small change of definition? That habit is worth more than any single result.

So a Chichester teenager should keep learning to code in 2026, beside walls the county history traces back to Roman times: AI can find a pattern in seconds, but people still have to decide whether it is real. The longer argument is in why coding is worth learning in 2026.

Delivery

Summersdale, Whyke or Fishbourne, with no journey to class

Chichester's learners live inside and around the walls, in the villages along the Lavant and out towards the harbour. Online, every one of them is the same distance from the lesson.

Inside and outside the walls

A learner in Portfield and another in Donnington can share one class without either of them crossing the city.

Levels that match school

Families will recognise our stages, which run alongside the English curriculum from primary school to GCSE and A level; all teaching is in English.

The free lesson in practice

In the opening session the learner builds something real, and the teacher then suggests a starting level, a course and a regular weekly time. There is no card to hand over.

Classes set by level

Groups of five to ten learners at the same stage, from Chichester, other parts of the UK and abroad, so every level has sensible times.

A weekly routine

Two fixed lessons a week, roughly eight a month, with half terms and exam weeks arranged with the teacher in advance.

Teaching across time zones

At 5 pm in Chichester it is 9.30 pm for our teachers in India in summer and 10.30 pm in winter, since India does not put its clocks forward; they fit their evenings around families here.

Across West Sussex

Learners in Bognor Regis, Selsey, Midhurst or Bosham join exactly the same classes, because every lesson is online and classes are grouped by level.

Fees

Chichester lesson fees

The first lesson is free, and after that there is one monthly fee.

First classUSD 0

A whole lesson free of charge, finishing with our advice on level, course and a weekly slot.

Group tuitionUSD 100

Roughly eight live lessons a month, in a group of five to ten learners at the same stage.

Private tuitionUSD 150

Roughly eight live lessons a month, with a teacher who works with your learner alone.

Families in Westhampnett or Apuldram are billed in US dollars, as is every family outside India, and our site shows no pound prices. Charges begin only after the free lesson, once you have agreed a course and a weekly slot with us; the pricing page sets out how pauses, missed lessons and moves between group and one-to-one teaching work.

FAQ

Chichester coding class questions

Questions Chichester families ask us most often.

How many people live in Chichester?

Census 2021 counted 124,068 usual residents in Chichester district. The middle-layer areas the House of Commons Library names College Lane and Oaklands, Central Chichester, and Stockbridge and Fishbourne had 12,300, 8,907 and 8,515.

How does Chichester compare with England?

The district is more thinly settled, at 157.8 residents per square kilometre against 433.5, and 4.1% of its residents were aged 85 or over in 2021, against 2.4% in England. In College Lane and Oaklands, 24.2% of residents aged five and over were students.

What is the Mann-Kendall test?

A test for a steady rise or fall over time. It compares every year with every later year, adds one when the later year is higher and subtracts one when it is lower, then asks how likely a total that large would be if the years were in random order.

Is the River Lavant flowing more often?

Counting any flow at all, days with flow rose from an average of 184.3 a year in the first 22 years to 218.3 in the last 22, with a p-value of 0.026. Counting only flow above 10 litres a second, there is no sign of a trend (p of 0.52), so the rise is in days of the barest trickle.

Where does the river data come from?

From the Environment Agency's hydrology data service, which publishes daily mean flow for the Lavant at Graylingwell with a quality flag on each day. We are not connected with the Environment Agency.

Are Chichester's city walls Roman?

The Victoria County History calls the walls and gates Roman in origin and sees no reason to think the line of the wall has changed since Roman times, though the visible stonework has been refaced many times. Historic England lists the City Walls at Grade I.

When do Chichester lessons happen?

Most Chichester learners take lessons straight after school, later on a weekday or on a Saturday or Sunday morning; the slot is fixed at the end of the free lesson. Our teachers work from India, where clocks read four and a half hours later than West Sussex while British Summer Time lasts and five and a half hours later the rest of the year.

Is there a centre in Chichester?

No. We have no Chichester centre and no premises anywhere in the UK, because every lesson is live online. A learner needs a computer with sound and a steady internet connection, and our phone number is Indian.

What do Chichester lessons cost?

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

How do you group learners?

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