Crawley has a single built-up area in the ONS figures, 120,550 people, part of which extends beyond the borough line. Local schools work to the national curriculum for England, and our calendar steps around whatever breaks you list. ### County and region The [West Sussex](/coding-classes-in-west-sussex) page covers the county, and the [South East](/coding-and-ai-classes-in-south-east-england) page links the region. The Crawley project ## Passengers per flight at Gatwick A mean of ratios is not the same as a ratio of totals. The learner downloads twelve monthly files from the Civil Aviation Authority, keeping the Gatwick row of Table 03 for air transport movements and Table 09 for terminal passengers. Dividing one by the other month by month gives passengers per movement: 157.6 in January, the lowest, rising to 177.6 in August, the highest, at the summer peak. The obvious next step is to average those twelve monthly figures. Python returns 164.13. | Calculation | Result | What it weights | | --- | --- | --- | | Mean of 12 monthly ratios, Gatwick | 164.13 | Every month equally | | Annual passengers divided by annual movements, Gatwick | 164.88 | Every flight equally | | Mean of 45 airport ratios, UK, July | 81.6 | Every airport equally | | Median of 45 airport ratios, UK, July | 81.2 | The middle airport | | All passengers over all movements, UK, July | 150.6 | Every flight equally | But the CAA also publishes Gatwick's annual totals, 42,769,164 passengers and 259,391 movements, and dividing those gives 164.88. The two answers differ because August, with more flights, should count for more than January, and a plain average of months ignores that. The average of averages treats a quiet month and a busy month as equals. At one airport the gap is under one passenger per flight, small enough that a careless program would never be caught. Across the country the same slip becomes huge. In July 2025 the CAA lists 45 UK airports with flights. Averaging their 45 ratios gives 81.6 passengers per movement, because tiny airfields count as much as Heathrow: Biggin Hill manages 0.9 passengers per movement, Gatwick 172.1 and Heathrow 192.4. Weighting each airport by its flights gives 150.6, nearly double. The learner also notes a data trap: adding up Table 05's three movement categories for December does not match Table 03's published total, so the program uses published totals and never rebuilds them from parts. ### Ages 8 to 11 Compare the average score of two classes of different sizes with the average of every pupil together. ### Ages 11 to 15 Read the Gatwick rows into Python and compute both averages. ### Ages 15 and up Repeat across all UK airports, explain the weighting, and write tests for both functions. ### CAA figures, our averages The monthly and annual figures come from the Civil Aviation Authority's UK airport data, and the airport position from OurAirports. The ratios and averages are our own calculations. Why Gatwick ## An airport inside the borough Gatwick in the CAA's 2025 figures. | Figure | Value | | --- | --- | | Terminal passengers, 2025 | 42,769,164 | | Air transport movements, 2025 | 259,391 | | Busiest month for passengers | August, 4,661,770 | | Quietest month for passengers | January, 2,541,908 | | Passengers per movement, August | 177.6 | | Passengers per movement, January | 157.6 | Weighting is everywhere once you look. School league tables, app store star ratings, average speeds on a journey and the performance numbers software engineers quote for their servers all hide a choice between averaging groups and averaging individuals. Two honest programmers can report different "averages" from identical data. A Crawley learner who has worked through the Gatwick figures will always ask what each average weights before comparing two of them. Modern Age Coders is not connected with the Civil Aviation Authority, Gatwick Airport, OurAirports or the ONS. The figures are theirs; the averages, and any mistake in them, are ours. Stages by year ## From class averages to real datasets Treat the year labels loosely; placement follows the free lesson. Years 1 to 4 ### Counting and blocks Block coding with scores, counts and simple averages. [Coding for Kids](/courses/kids-coding-blocks-masterclass)[Scratch Coding for Kids](/courses/scratch-programming-complete-course)Years 5 to 8 ### Python and tables Lists, division and reading data files in Python. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Years 9 to 13 ### Statistics and AI Weighted averages, data and AI beside GCSE and A level. [Python for Teens](/courses/python-complete-masterclass-teens)[High School Mathematics](/courses/complete-high-school-mathematics-mastery)Adults ### Data at work Adult Python and data analysis. [Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)AI and averages ## Does an AI know which average you need? The wrong weighting gives a confident wrong number. Ask a chatbot for the average passengers per flight across UK airports and it may average the airports, producing a figure about half the real one. The arithmetic is flawless; the question it answered is not the one asked. A Crawley learner who has compared 81.6 with 150.6 knows to ask what each average counts equally. Choosing the average that fits the question is precisely why coding still repays Crawley teenagers in 2026. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Lesson details ## Across Crawley, live online Every neighbourhood in the borough joins by video. ### Code by the student Learners type every line; the tutor follows the shared screen and asks questions rather than taking over. ### A start that fits Whether in Year 3 or Year 12, the starting point comes from school year plus what the trial shows, and the correct exam board is used. ### No-cost first lesson The trial is free and ends with honest advice. ### Level-matched groups Classes of five to ten UK learners at the same stage. ### Two lessons weekly Twice a week in term time; holidays left free. ### Fixed hour UK clock changes are handled by our teachers, so your time stays the same. Why the groups are online Five Crawley learners at one stage, all free at the same hour, seldom live close together. Online groups solve it. Fees ## Crawley fees Crawley families pay the same fee as every family outside India. First class**USD 0** A full free lesson with a clear course recommendation. Group tuition**USD 100** About eight live small-group lessons a month. Private tuition**USD 150** About eight live private lessons a month. All prices are in US dollars rather than sterling. We send no invoice before the free lesson has matched the learner to a course and a regular time. Holidays, missed sessions and changing between shared and private lessons are all described on the pricing page.

Submitted details are used for placement and follow-up. FAQ ## Crawley questions The town, the Gatwick project and practical points. ### What is the population of Crawley? The 2021 census counted 118,491 in Crawley borough; the ONS gives 120,550 for the Crawley built-up area. ### Can I learn coding and Python online from Crawley? Certainly; our live coding, Python, AI and maths lessons are open to anyone in Crawley between 6 and 67. ### What is the Gatwick project? Learners use Civil Aviation Authority data to compute passengers per flight two ways and see why an average of averages differs from a ratio of totals. ### What is an average of averages? An average of group averages that ignores group size; it counts a small group as much as a large one. ### Is Gatwick Airport in Crawley? Yes. The airport's published position and the postcodes around it fall inside Crawley borough. ### Do lessons happen in person? No, they are live online, so anywhere in the borough works. ### Can exam-year students get support? GCSE and A level maths and computing are covered, with understanding as the target and no guarantee of any grade. ### Who is eligible? From 6 to 67, adults included. ### How much do lessons cost? Nothing for the trial; after it, USD 100 per month buys a group place and USD 150 per month a private tutor. ### Are there lessons in school holidays? They stop for the break once you give us the dates.
