On postcodes.io, Cadoxton, Gibbonsdown, Palmerstown and Barry Dock appear as suburban areas in the CF63 district, and Colcot, Barry Island and Merthyr Dyfan in CF62. Schools in the Vale follow the Curriculum for Wales, so we place learners by Welsh school year and use WJEC names for GCSE and A level. Lessons are taught in English. Send the term dates and we will keep holiday weeks free. ### The Vale, Cardiff and WJEC help There is more on [coding classes in the Vale of Glamorgan](/coding-classes-in-vale-of-glamorgan), [Cardiff](/best-coding-class-in-cardiff) and [WJEC GCSE Computer Science help](/wjec-gcse-computer-science-help-wales). Why reasoning comes before tools is set out on [learn to think, not just use AI tools](/learn-to-think-not-just-use-ai-tools-uk). The Barry project ## k-anonymity on a census table: how small is too small? Count the households hiding in tiny cells, then blur the table two different ways and count again. The learner downloads Census 2021 table TS017, household size, from the Nomis API for all 434 output areas in the Vale of Glamorgan. The area rows add up to 57,452 households sorted into eight sizes, from one person to eight or more. The published county total is 57,446, six fewer, and that small gap is itself a privacy measure, as explained below. Each combination of an area and a size is a cell. Two columns, where you live and how many live with you, are things a neighbour would know; privacy researchers call such columns quasi-identifiers. A household is exposed at level k if its cell holds fewer than k households. | Areas | Household-size groups | Cells under 5 | Households in them | | --- | --- | --- | --- | | 434 output areas | 8 sizes | 571 | 1,134 (1.97%) | | 434 output areas | 1, 2, 3, 4, 5 or more | 146 | 430 (0.75%) | | 434 output areas | 1, 2, 3 or more | 0 | 0 | | 82 larger areas (LSOAs) | 8 sizes | 109 | 209 (0.36%) | | 82 larger areas (LSOAs) | 1, 2, 3, 4, 5 or more | 0 | 0 | At full detail, 571 of the 3,472 cells hold between one and four households, 1,134 households in all, and another 930 cells are empty. Of those 571 small cells, 555 are for households of five or more people: homes that size are scarce in any one area, so they are easy to pick out. There are two ways to blur. Merging the sizes into "five or more" cuts the exposed households to 430 but does not finish the job. Keeping all eight sizes and moving to larger areas leaves 209. Doing both, five groups across 82 areas, leaves no cell under five, and the smallest holds 12. So does keeping the small areas and using only three groups, but that throws away nearly everything the table said about larger households. Raising k raises the price. At k of 10 the full-detail table has 854 small cells covering 3,033 households, 5.28% of the county. One caution belongs on the page: the ONS already adjusts small census counts slightly to protect people, which is why the rows add to 57,452 while the county total reads 57,446. These published numbers are the table a reader sees, not exact truths. The exercise is about how to reason over any table, including ones nobody has protected. ### Ages 8 to 11 Play a guessing game: how few clues does it take to pick one classmate out of thirty? ### Ages 11 to 15 Load the Vale household table in Python and list every cell that holds fewer than five. ### Ages 15 and up Measure k-anonymity at several levels of detail and chart what each level of safety costs. ### Census table, our counting Household counts are Office for National Statistics Census 2021 data from Nomis, under the Open Government Licence, and already carry the ONS's own disclosure protection. The cells, groupings and percentages are our calculations. Nothing here identifies any household, and no attempt was made to. Privacy and AI ## What this teaches about vibe coding and AI agents Removing names is the start of protecting data, not the end. | In the household table | When data goes into an AI tool | | --- | --- | | 571 cells held fewer than five | Rare combinations can identify people | | Area and household size were enough | Ordinary columns act as identifiers | | Merging sizes left 430 exposed | One fix is often not enough | | Both fixes together left none | Privacy is bought with lost detail | | The ONS had already adjusted small counts | Ask what protection a dataset already has | People now paste spreadsheets into chatbots and ask agents to analyse customer lists without a second thought. Vibe coding means describing a program while an AI writes it; our Barry learners first ask which columns could point to a person, and have the code check cell sizes before any chart is drawn. An AI agent with access to files should be given the same rule: count before you publish. Building agents waits for confident Python, so it mostly suits sixth formers and adults, and anything in Copilot Studio is done in private lessons.

Modern Age Coders is not connected with the Office for National Statistics, Nomis or postcodes.io. We used their open data only, and the analysis and any mistakes are our own. Stages ## From guessing games to privacy-aware data work A Welsh school year tells us roughly where to begin; the free lesson tells us exactly.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Generative AI Course](/courses/complete-generative-ai-masterclass-college)AI and privacy ## What is k-anonymity, and is anonymous data really anonymous? A dataset is k-anonymous when every combination of its identifying columns is shared by at least k records; data with names removed can still fail that test and point to individuals. In a Census 2021 table whose rows add to 57,452 Vale of Glamorgan households by small area and household size, 1,134 households sat in cells of fewer than five; merging sizes and using larger areas together removed every such cell. Learners who have run that count ask of any dataset given to an AI: which columns could single someone out, and how small is the smallest group? A Barry teenager who checks cell sizes before sharing data is already working more carefully than many adults, and that care is learned by writing the code. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). How it works ## How a Barry lesson reaches you A laptop or desktop with a camera, plus home broadband steady enough for video, is all the kit required. ### Hands on the keyboard Our tutors do not type for anyone. The Barry learner shares a screen, writes and runs the program, and explains each step when asked. ### Trial first, plan second What the free lesson shows decides the first topic; a WJEC course is noted if there is one. ### A trial with no bill One full lesson of real teaching, free, closing with a course suggestion. ### Classes built by level Between five and ten people, drawn from all over Britain, who have reached the same point. ### Twice weekly in term Roughly eight sessions a month, with Vale holiday weeks left clear. ### Your hour is fixed When British clocks shift in March and October, the tutor adjusts and you do not. Why not a classroom in Barry? A class only works if everyone in it is at one level, and a single town seldom supplies enough of them on one evening. A video call can draw on the whole country. Fees ## Barry fees Our fees outside India are one flat list, and Barry is on it. First class**USD 0** A complete trial lesson without charge, and advice at the end of it. Group tuition**USD 100** A seat in a level-matched class, around eight sessions monthly. Private tuition**USD 150** A tutor for one learner, around eight sessions monthly. Fees are in US dollars, not sterling. Nothing is billed until the trial has settled which course and which evening. Rules on holiday weeks, absences and moving between group and private lessons sit on the pricing page.

FAQ ## Barry questions Data privacy, the census project, Python, vibe coding and practical points. ### What is the population of Barry? The ONS gives 56,605 usual residents for the Barry built-up area at the 2021 census; the Vale of Glamorgan had 131,939. ### Can someone in Barry join these AI and programming classes? Yes. Every lesson is a live video call, open to ages 6 to 67 anywhere in Barry or the wider Vale of Glamorgan. ### What is a quasi-identifier? A column that is not a name but can help pick someone out when combined with others, such as area, age or household size. ### How do you make data k-anonymous? By generalising: merge rare categories, use larger areas or wider bands, or remove the rarest records, until every combination is shared by at least k records. Each step loses detail. ### What does the Barry project involve? Counting how many of the 57,452 households in the rows of a census table sit in cells smaller than k, then merging categories and areas to see what level of detail is safe. ### Is vibe coding part of the lessons? It is, from primary age upward. A learner states what the program should do, lets an AI draft it, then reads and tests the draft. ### At what point do AI agents come in? After a learner can write Python alone, which tends to mean sixth form age or adulthood. Copilot Studio agent work is private-lesson only. ### Can lessons run beside WJEC courses? They can. We cover WJEC GCSE and A level computer science and maths topics so they make sense, and we make no promises about results. ### How much are the classes? Nothing for the trial. Group classes are then USD 100 monthly and private lessons USD 150 monthly. ### What happens at half term and in the summer? Lessons stop for the Vale school holidays once we have your dates, and restart the week after.
