Gloucester today

A compact city of young families

Census 2021 figures for Gloucester, from the Office for National Statistics via Nomis, set beside England.

Gloucester, Census 2021
Measure	Gloucester	England
Usual residents	132,416	56,490,048
Living in households	130,621	Not compared
Aged 5 to 9	8,331 (6.3%)	5.9%
Aged 10 to 14	8,170 (6.2%)	6.0%
Aged 30 to 34	9,807 (7.4%)	7.0%
Students among residents aged 5 and over	25,155 (20.1%)	20.4%
Usual residents per square kilometre	3,266.6	433.5

Children and parents

Every band from birth to fourteen, and the early thirties, made up a larger share of Gloucester's residents in 2021 than of England's.

Students close to average

Of 124,957 residents aged five and over, 25,155 were at school or in full-time study, 20.1%, almost exactly the English figure.

A tight boundary

At 3,266.6 residents per square kilometre, the council area holds the city itself, with most of the surrounding countryside in neighbouring districts.

Our Gloucester learners reflect that mix of families. A Year 2 child in Kingsholm might be making first steps in code, a Year 10 student in Tuffley preparing for GCSE Computer Science, and a parent in Quedgeley learning Python for work, each in a group at the same level.

Thirteen centuries on one site

A cathedral with the world's earliest known fan vaulting

From Gloucester Cathedral's own heritage pages.

678 to 679 AD

The Cathedral describes its site as one of continuous Christian worship since then, more than 1,300 years, with architecture spanning almost a thousand.

The Great Cloister

Built in the late fourteenth century, it contains what the Cathedral calls the earliest known example of fan vaulting anywhere in the world.

A king's tomb

The Cathedral counts the tomb of a king among the things visitors come to discover, one of many layers of history in the building.

We have no connection with Gloucester Cathedral. Fan vaulting opens this page because it is pattern made precise: the same curved shape repeated and fitted together until the whole ceiling reads as one design. The project below is about fitting patterns too, deciding when the rise of the river at Sharpness and the rise at Gloucester are really the same event seen twice.

Where the river readings come from

The Environment Agency's flood-monitoring service publishes recent river levels for its gauges, every five minutes at Sharpness and every fifteen at Epney, Minsterworth and Gloucester, as heights on each gauge's own scale.

Signature project

Following the tide from Sharpness to Gloucester

Dynamic time warping aligns two sequences by letting one run faster or slower than the other, finding the stretching that makes them match most closely.

River Severn gauges, 25 August to 23 September 2026, compared with the Sharpness record
Question	Answer	Detail
High tides seen at Sharpness	54	Two a day for four weeks
Tides that lifted Gloucester by 0.3 m or more	16	Smallest such Sharpness tide 7.57 m
A bigger tide that did not	7.76 m	The threshold is not a sharp line
Delay from Sharpness to Gloucester peak	105 to 240 minutes	Median 120, for tides that arrived
Gap after the closest single fixed delay	0.849	Standard deviations, with a 150-minute delay
Gap after dynamic time warping	0.547	Within a four-hour band

1. Put records on one clock

The gauges report at different intervals and occasionally miss a slot. Every reading goes onto one 15-minute grid first, so like is compared with like.

2. Try one delay

Slide the Gloucester record back in time and measure the gap. The closest single delay, 150 minutes, still leaves a mean gap of 0.849 standard deviations.

3. Let the delay vary

Dynamic time warping builds a table of partial matches and finds the cheapest path through it, allowing the delay to change from tide to tide within a four-hour band.

A flexible match will find something

Warping cut the gap to 0.547, which looks like a clear win. But in four weeks, 38 of the 54 tides lifted Gloucester by less than 30 centimetres, and during those neap tides the warping path still bent itself to pair Sharpness with whatever the river was doing upstream. Dynamic time warping always returns a match. Whether the matched pieces are the same event is a question the learner has to answer separately.

For the tides that clearly arrived, the story is consistent. The largest, 9.69 metres on the Sharpness gauge at 20:45 GMT on 12 September, lifted Gloucester by 1.65 metres about two hours later. Across all 54 tides, the height at Sharpness and the rise at Gloucester correlate at 0.79, but the dividing line is fuzzy: a 7.57-metre tide got through while a 7.76-metre one did not, so the height at Sharpness is clearly not the only thing that matters on the day.

Matching sequences

Five questions before trusting an alignment

Learned on a tidal river, then used on speech recognition, handwriting, step counts in sports watches, gestures, music and sensor streams from machines.

Using dynamic time warping without fooling yourself
Question	For the Severn gauges	What it prevents
Are the clocks the same?	All readings moved onto one 15-minute grid in UTC	Comparing a reading with the wrong moment
How much stretch is allowed?	A band of four hours	Pairing a tide with the next day's
Is the event present in both?	Only 16 of 54 tides clearly reach Gloucester	Aligning a signal with noise
What is the baseline?	The closest fixed delay, 150 minutes	Praising a gain that a simple method nearly matches
What do the heights mean?	Each gauge uses its own datum	Comparing numbers that are not on one scale

The last row trips people up. Each gauge reports height above its own reference level, so 9.69 at Sharpness and 1.89 at Gloucester cannot be compared directly. That is why the project standardises each record before aligning them, and talks about rises rather than raw heights when it asks whether a tide arrived.

Younger learners

Two people clapping a rhythm at slightly different speeds, and working out which claps belong together.

Teenagers

Four gauge records in Python, a shared time grid, a fixed-lag comparison and dynamic time warping written from scratch.

Adults

Comparing time series at work, from machine sensors to sales, with the alignment rules and baselines stated.

We have no connection with the Environment Agency, Gloucester Cathedral or Gloucester City Council. The gauge readings and census tables are published openly; the alignments, rises and comparisons shown are our own calculations and make no flood forecast.

Learning ladder

From clapping in time to dynamic time warping

The age bands are a rough starting point, and the free lesson settles the right level.

Ages 6 to 10

Coding and AI

AI tools match patterns automatically. Why should a Gloucester teenager learn how alignment works?

Because an algorithm that always finds a match needs a person who asks whether it is real.

Hand an assistant two river records and ask how well they line up, and it may run dynamic time warping and report a close match. It will not point out that most of the tides never reached Gloucester. A learner who has watched the warping path bend around neap tides knows to check that the event exists in both records before celebrating the fit.

Sequence alignment runs through AI: recognising speech, reading handwriting, comparing movements and matching patterns in sensor streams. The same caution applies everywhere. Flexible matching is powerful precisely because it can fit almost anything, which is why the people who build these systems test whether the matches mean what they seem to.

So a Gloucester teenager should still learn to program in 2026, in a city whose cloister first made fan vaulting fit together: the algorithm finds a fit, but deciding whether the fit is true is still up to us. The longer argument is in why coding is worth learning in 2026.

Delivery

Kingsholm, Barnwood or Quedgeley, from home

From Longlevens to Quedgeley, a school-run crossing of Gloucester takes time. A live online lesson takes none.

North to south of the city

A learner in Longlevens and another in Abbeymead can join the same lesson without anyone driving across town.

Stages from Reception on

We use the stages Gloucester schools use, Reception and Key Stages 1 to 4 through to GCSE and A level, and we teach in English.

A free lesson worth the time

The first session is real teaching and ends with a suggested level, course and weekly time. Nobody asks for card details.

Groups of five to ten

Everyone in a group is at the same stage, drawn from Gloucester, the rest of the UK and abroad, so each level has a workable hour.

A twice-weekly habit

Two fixed lessons each week, about eight a month, with school holidays and exams planned with the teacher in advance.

Teachers on Indian time

A 4 pm class in Gloucester begins at 8.30 pm in India in British Summer Time and 9.30 pm in winter, because India never changes its clocks; our teachers work those evenings for UK learners.

Across Gloucestershire

Families in Cheltenham, Stroud, Tewkesbury or the Forest of Dean join exactly the same classes, as lessons are online and groups form by level.

Fees

Gloucester lesson fees

One free lesson, then a single monthly fee.

First classUSD 0

FAQ

Gloucester coding class questions

The questions Gloucester families ask us most.

How many people live in Gloucester?

The 2021 census counted 132,416 usual residents in the Gloucester council area, with 130,621 living in households and 1,795 in communal establishments such as care homes and halls.

How does Gloucester compare with England?

Gloucester has more children than average: in 2021, 6.3% of residents were aged 5 to 9 (England 5.9%), while 20.1% of those aged five and over were students (England 20.4%). It had 3,266.6 residents per square kilometre (England 433.5).

What is dynamic time warping?

A method for comparing two sequences that may run at different speeds. It finds the stretching and squeezing of time that makes them match most closely, within limits the user sets.

Does every tide reach Gloucester?

No. In four weeks of Environment Agency readings, only 16 of 54 high tides at Sharpness lifted the river at Gloucester by 30 centimetres or more; the biggest raised it by 1.65 metres about two hours later.

Where do the river readings come from?

The Environment Agency's flood-monitoring service, which publishes recent levels for its gauges at Sharpness, Epney, Minsterworth and Gloucester as heights on each gauge's own scale.

What is special about Gloucester Cathedral?

The Cathedral says its Great Cloister, built in the late fourteenth century, contains the earliest known example of fan vaulting in the world, and that worship on the site goes back to 678 to 679 AD. We are not connected with the Cathedral.

When do Gloucester lessons take place?

Most Gloucester families pick a weekday slot straight after school or later in the evening, and some prefer Saturdays; we fix the time together during the free lesson. Our teachers are four and a half hours ahead in summer and five and a half in winter.

Is there a Modern Age Coders centre in Gloucester?

No. There is no Gloucester centre and no premises anywhere in the UK; every lesson is taught live online. Learners need a computer with sound and a steady connection, and our phone number is Indian.

How much do Gloucester lessons cost?

The first lesson is free. After it, a group place is USD 100 a month for two live lessons a week, about eight a month, with five to ten learners, and one-to-one lessons on the same pattern are USD 150 a month. Course, format and time are agreed before any charge.

How are Gloucester groups formed?

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