Town figures are ONS built-up areas, each checked against our own count of census output areas. | Town | Residents | Town | Residents | | --- | --- | --- | --- | | Sheffield | 500,535 | Adwick le Street | 18,325 | | Doncaster | 87,455 | Wath upon Dearne | 16,960 | | Rotherham | 71,535 | Wombwell | 16,765 | | Barnsley | 71,405 | Maltby | 16,310 | | Wickersley and Bramley | 24,655 | Swinton | 15,910 | | Chapeltown and High Green | 22,180 | Mexborough | 15,555 | Sheffield borough had 556,521 residents, Doncaster 308,106, Rotherham 265,807 and Barnsley 244,572. The ONS Sheffield area spills a little into Rotherham, and below the big four comes a long list of towns of roughly fifteen to twenty-five thousand people, including Rawmarsh, Hoyland, Darton, Armthorpe, Thorne and Rossington. Every published figure matches our own count to within a few people. School holidays differ between the four councils and the academy trusts; we have not read their calendars, so each family tells us its own dates. ### Two city pages already Our [Sheffield](/best-coding-class-in-sheffield) page fits trend lines to a record, and [Doncaster](/best-coding-class-in-doncaster) is about searching cleverly. This page is for the whole county, Rotherham and Barnsley included. The South Yorkshire project ## What is a snooker break worth? A model with one number in it, the arithmetic of chance, and a reality check from the Crucible. The model is deliberately simple. The player pots each ball with the same chance p, every shot independent of the last, and always takes red then black fifteen times before clearing the six colours: 36 pots worth 147 points. The break ends at the first miss. The chance of reaching the tenth pot is p multiplied by itself ten times, so the expected value of a break is the value of each ball times the chance of getting that far, added up. The learner writes it as a short loop, then checks it with 200,000 simulated breaks, which agree. | Chance of each pot | Expected break | Middle break (median) | Chance of a 147 | | --- | --- | --- | --- | | 80 per cent | 14.7 | 9 | 1 in 3,081 | | 90 per cent | 33.9 | 24 | 1 in 44 | | 95 per cent | 63.2 | 49 | 1 in 6 | | 98 per cent | 102.0 | 134 | About 1 in 2 | Two lessons come straight out of the table. First, the average and the typical break are different things. At 90 per cent the expected break is 33.9, but half of all breaks are 24 or less, and nearly half are under 20: a few long breaks pull the average up. At 98 per cent the pattern flips, and the middle break is higher than the average. Second, chances that multiply compound fast. Raising the pot rate from 90 to 95 per cent makes a 147 seven times more likely, because the improvement is applied 36 times over. Now the reality check. The model says a player potting 95 per cent of the time should make a 147 in about one break in six. Yet WST notes only 14 maximums in 46 years at the Crucible, across many thousands of frames played by the top professionals. The model is not just a little out; it is wrong by a huge margin. That is its most useful result, because it points straight at the assumptions: shots are not equally hard, the black is not always available after a red, the cue ball has to be placed for the next shot, and players choose safety instead of risk. A model that fails loudly teaches more than one that nobody checks. ### Ages 9 to 12 Roll a die for each pot, stop at the first six, add up the points, and compare the class's average break with the middle one. ### Ages 12 to 15 Write the expected-value loop in Python for different pot rates and plot how the chance of a 147 changes. ### Ages 15 and up Compute the full distribution exactly, confirm it by simulation, then add a harder shot type and see how far the 147 rate falls. ### What is WST's and what is ours The description of a 147 and the Crucible maximum figures come from World Snooker Tour's website. The model, its pot rates and every number in the table are ours, invented for teaching; they do not describe any real player. Why the Crucible ## A Sheffield theatre and snooker's perfect break The South Yorkshire link, in the words of the people who run it. | Source | What it says | | --- | --- | | Sheffield Theatres | The world-famous Crucible is a Sheffield landmark with a distinctive stage. | | World Snooker Tour | The Crucible is the home of the World Championship. | | World Snooker Tour | A 147 means potting all 15 reds with blacks, then clearing the colours. | | World Snooker Tour | In 46 years at the Crucible there had been only 14 maximum breaks, by ten players. | Snooker is a lovely way into probability because every shot is a chance and every break a chain of them. The same arithmetic runs through product reliability, where a device fails if any one part fails, through medicine, where several tests must all be passed, and through any process with many steps that must all go right. A South Yorkshire student who has built the model and caught its mistake knows both how to calculate with chances and how far to trust the answer. We have no link with World Snooker Tour, Sheffield Theatres or any South Yorkshire council. Their facts are theirs; the model and any error in it are ours. Nearby pages [Sheffield](/best-coding-class-in-sheffield) and [Doncaster](/best-coding-class-in-doncaster) have their own pages; [Derbyshire](/coding-classes-in-derbyshire) and [Nottinghamshire](/coding-classes-in-nottinghamshire) are south, [Leeds](/best-coding-class-in-leeds) north. The path ## From keeping score to reasoning about chance The free lesson settles the starting point. Age is a hint; skill decides. Ages 6 to 10 ### Scores and dice Block coding games with scores, dice and turns, where children first see chance at work. [Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Ages 8 to 13 ### Games in Python Typed Python that plays a game many times and counts what happens. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Ages 13 to 18 ### Probability properly Expected value, distributions and simulation, from GCSE ideas through to A level statistics. [Statistics & Probability](/courses/statistics-probability-maths-course)[Data Science for Teens](/courses/data-science-course-for-teens-python-data)Ages 18 to 67 ### Risk and data Data, statistics and AI tools for adults who weigh odds and risks in their work. [Data and AI Analytics for Non-Programmers (Excel, Sheets, Power BI)](/courses/data-and-ai-analytics-for-non-programmers-course)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and models of chance ## An AI can compute an expected value instantly. Will it check the model against the world? The arithmetic is easy. Noticing that the model disagrees with reality is the skill. Ask an assistant for the chance of a 147 if a player pots 95 per cent of shots, and it will multiply correctly and answer about one in six. Unless asked, it will not set that beside the Crucible record of 14 maximums in 46 years and conclude that the assumption of equal, independent shots must be badly wrong. The answer is correct for the model and useless for the game. A South Yorkshire student who has made that comparison will ask the same of any number an AI produces: what does the model assume, and does its answer match what actually happens? That habit protects against confident nonsense in forecasts, risk scores and predictions of every kind. For a teenager in South Yorkshire, learning to code in 2026 means being able to put any model up against the real world before trusting it. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Lesson logistics ## From the Dearne to the Don, straight from home Crossing South Yorkshire for a weekly class in the evening rush takes time many families do not have. Online lessons give it back. ### Lessons at your table A semi in Wickersley, a terrace in Wombwell, a flat in Doncaster. The teacher and learner share a screen, and the learner writes the code. ### School words we use Whether it is a Year 7 homework project or an A level statistics topic, the teacher uses the terms South Yorkshire pupils hear in class, in English. ### First lesson free A proper lesson, then honest advice on level and course. No card details are asked for. ### Your level, your group Everyone in a group of five to ten is working at the same point, wherever in the world they log in from. ### Breaks to match school Two lessons a week is typical, with pauses for your school's holidays. ### Held in UK time Slots are fixed in UK time and ignore the clock changes on your side; the teacher, running on India time several hours ahead, adjusts. Why groups follow level Even in a borough of a quarter of a million, five learners at one stage free on the same evening are hard to find. Level-based groups let a learner in Thorne or Hoyland join the right class. Fees ## Fees in South Yorkshire Maltby or Mexborough, the fee is the same, as it is in every country we teach apart from India. First class**USD 0** A full lesson of genuine work, finishing with advice on level and course. Group tuition**USD 100** About eight lessons a month with five to ten learners at one level. Private tuition**USD 150** About eight lessons a month with a teacher of your own. All prices are set in US dollars, with none in pounds. You are only billed once the free lesson has led to an agreed course and a fixed weekly slot. How pauses, missed classes and swaps between group and private teaching work is spelled out on the pricing page.

Add the four boroughs together, Sheffield 556,521, Doncaster 308,106, Rotherham 265,807 and Barnsley 244,572, and you get 1,375,006 usual residents in the 2021 Census. The borough figures are the ONS's on Nomis; the total is our addition. ### What are the largest towns in South Yorkshire? By ONS built-up area: Sheffield 500,535, Doncaster 87,455, Rotherham 71,535, Barnsley 71,405 and Wickersley and Bramley 24,655. ### What is the snooker project? Learners model a break where every pot has the same chance, compute its expected value and the chance of a 147, check it by simulation, and compare it with the Crucible's real record to find the model's wrong assumptions. ### What is expected value? The average result you would get over a very large number of tries, found by multiplying each outcome by its chance and adding up. It is not the same as the typical result when outcomes are lopsided. ### Why does the Crucible matter here? World Snooker Tour calls it the home of the World Championship and records only 14 maximum breaks there in 46 years, a real figure that shows how far a simple model can be from reality. ### Are classes held in South Yorkshire? No. No. Everything happens live over video, so a learner in Thorne has the same class as one in Sheffield. ### Is there an age limit? We teach from 6 up to 67. Blocks and games come first for the youngest, typed Python tends to start between eight and ten, teenagers can go deep into statistics and data science, and adults usually focus on data skills. The free lesson decides where each person begins. ### Do you teach statistics and probability? Yes, from first ideas to A level topics, using code to run experiments. We help learners understand; we do not promise grades. ### What does it cost? The first lesson is free. Staying on costs USD 100 monthly in a small group or USD 150 monthly with a private teacher. There is nothing to pay to join and no minimum commitment. ### Do you break for South Yorkshire school holidays? If you want us to. Sheffield, Doncaster, Rotherham and Barnsley councils and academy trusts publish dates, and we plan around yours.
