Every figure is for Greater Sydney, compared with Australia as a whole. | Measure | Greater Sydney | Australia | | --- | --- | --- | | People | 5,231,147 | Not compared | | Median age | 37 | 38 | | Families | 1,380,176 | Not compared | | Private dwellings | 2,076,284 | Not compared | | Occupied homes that are a flat or apartment | 561,988, or 30.7% | 14.2% | | Employed people working as professionals | 711,729, or 29.3% | 24.0% | ### Apartment living 30.7% of Greater Sydney's occupied private dwellings were flats or apartments in 2021, more than double the national share of 14.2%. ### A professional workforce Professionals made up 29.3% of employed Sydney residents aged 15 and over, against 24.0% across Australia. ### Plenty of school-age learners The Census counted 329,072 Greater Sydney residents aged 5 to 9, 6.3% of the population, the age at which many of our Scratch learners begin. One habit we keep, and teach. The age bands and dwelling types in a census table are each adjusted on their own to protect privacy, so their parts are never guaranteed to add up to the published total. This page quotes the published total and the published shares, and never adds the bands up to make a figure of its own. Signature project ## Which bus stop is in the middle, and do we need to sort them all to find it? Every bus stop OpenStreetMap records in our inner-Sydney rectangle, measured from Town Hall station, and two ways to find the middle one. | Measure | Figure | | --- | --- | | Bus stops in the rectangle | 885 | | Middle (median) distance from Town Hall station | 2,781.6 metres | | Stops within 500 metres of Town Hall | 37 | | Stops within 1 kilometre | 128 | | Nearest stop | Town Hall, Park St, Stand J, 86 metres away | | Farthest stop in the rectangle | 6,029 metres | ### 1. Sort, then look Python's built-in sort put the 885 shuffled distances in order with 7,496 comparisons. The middle value is then simply position 443. ### 2. Select, do not sort Quickselect picks a pivot, splits the list into nearer and farther, and keeps only the side that holds the middle. Over 200 shuffled runs it averaged 2,974 comparisons. ### 3. Break it on purpose Hand quickselect a list that is already sorted and let it always pivot on the first element. It needed 293,709 comparisons, close to checking every pair. ### The sorted-list surprise, both ways round An already sorted list is the worst case for naive quickselect, yet Python's own sort finished the same sorted list in just 884 comparisons, because its algorithm notices runs that are already in order. One input, opposite verdicts. Choosing the pivot at random fixed quickselect: 3,790 comparisons on the sorted list. That is the lesson in one line: how an algorithm performs depends on the data it meets, not only on its name. The figures are ours, measured on an OpenStreetMap snapshot taken on 7 October 2026. OpenStreetMap is mapped by volunteers, so a stop that exists may be missing or a removed one may linger; the rectangle is our own choice, not an official boundary. Distances are straight lines over the Earth's surface from the Town Hall station node, not walking routes. None of that changes the lesson, which is about counting the work an algorithm does on whatever list it is given. Selecting instead of sorting ## Five habits for finding the one value you need First learned on 885 bus stops, then used on test marks, house listings, sensor readings and any list too long to sort for one answer. | Habit | What it looks like | What it saves you from | | --- | --- | --- | | Ask what you actually need | One median, or the ten nearest, rather than the whole ordering | Sorting thousands of rows to read three | | Count the work | Put a counter inside every comparison and print it | Believing an algorithm is fast because it has a famous name | | Randomise the pivot | Choose the splitting value at random, not the first item | The sorted-input disaster of 293,709 comparisons | | Test the awkward inputs | Run on sorted, reversed and repeated values as well as shuffled ones | Code that works on demo data and stalls on real data | | Check against the slow way | Confirm the selected value equals the sorted list's middle | A fast answer that is quietly wrong | The last habit is the one we insist on. Every quickselect run in our experiment was checked against the fully sorted list, and all 200 agreed. A faster method only earns its place once it has been shown to give the same answer as the obvious one. ### Younger learners A card game: twenty numbered cards face down, and a race to find the middle card by splitting piles instead of laying every card out in order. ### Teenagers The real 885 Sydney distances in Python, a comparison counter, quickselect written from scratch and then deliberately broken with a sorted list. ### Adults Selecting the top or middle rows of a large open data file with a few lines of code, and knowing when sorting everything is still the right call. We are not connected with Transport for NSW, OpenStreetMap, the Australian Bureau of Statistics or the Bureau of Meteorology, and no link with any of them is implied. Census figures are the Australian Bureau of Statistics' own; the distances and comparison counts are our calculations from OpenStreetMap data. Around the city ## A weather station from 1859 and a transport hub in every direction Sydney's public data goes back a long way, and some of it is updated every half hour. ### Observatory Hill The Bureau of Meteorology publishes half-hourly readings from the station it names Sydney - Observatory Hill, and its Climate Data Online lists daily maximum temperature records for that site going back to 1859. ### Twenty-four stations in one rectangle Our inner-Sydney rectangle holds 24 OpenStreetMap nodes tagged as stations, including Central Grand Concourse, Circular Quay, Wynyard and light rail stops such as Capitol Square. ### Stands by the letter Several of the stops nearest Town Hall are named by stand letter on Park Street, Druitt Street and York Street, which is why the ten nearest stops all sit within 214 metres of the station. Why the stand letters matter to a programmer A list of stop names looks tidy until you notice that Stand J, Stand H and Stand K on Park Street are different places with almost the same name. Real data is full of near-duplicates like these, and deciding whether two records are one place or two is a question every data project meets early. Learning ladder ## From splitting a pile of cards to choosing an algorithm on purpose The age bands are a starting guide. The free lesson sets the real level. Ages 6 to 10 ### Splitting and sorting Programs that compare two numbers, swap them and repeat, and the surprise that some orders take longer than others. [Scratch Coding for Kids](/courses/scratch-programming-complete-course)[Coding for Kids](/courses/kids-coding-blocks-masterclass)Ages 11 to 13 ### Lists of real places Loading a list from a file, measuring distances and finding the nearest, the farthest and the middle. [Python and AI for Kids](/courses/python-ai-kids-masterclass)[Maths Through Coding](/courses/maths-through-coding)Ages 14 to 18 ### Counting the work Sorting and selection algorithms written by hand, comparison counters, and inputs chosen to break them. [Problem Solving for Teens](/courses/problem-solving-dsa-masterclass-teens)[Python for Teens](/courses/python-complete-masterclass-teens)Ages 18 to 67 ### Ranking data at scale Picking the rows that matter from large files and choosing the right tool for the size of the job. [Python Automation Course](/courses/python-ai-automation-masterclass-college)[Data and AI Analytics for Non-Programmers (Excel, Sheets, Power BI)](/courses/data-and-ai-analytics-for-non-programmers-course)Coding and AI ## An AI assistant will write quickselect in seconds. Why should a Sydney teenager still learn how it works? Because the version an assistant hands over often pivots on the first element, and that choice needed 293,709 comparisons on our sorted list. Ask an assistant for a function that finds the median without sorting and you will usually get tidy, correct-looking quickselect. Correct is not the same as safe. If the code always takes the first item as its pivot, it runs well on shuffled data and grinds on data that arrives already in order, which real data often does: timestamps, IDs and anything exported from a sorted table. Nothing in the code warns you. Only a learner who has counted the comparisons knows to ask where the pivot comes from. That is the skill we are really teaching: reading generated code with a question in mind. A Sydney student who has seen 2,974 comparisons turn into 293,709 because of one line will check the pivot in any selection code, check the base case in any recursion and check the empty list in any loop, whether the code came from a classmate, a textbook or an AI tool. So the case for learning to code in 2026 is not that machines cannot write code. It is that someone still has to know which line to distrust, and a Sydney learner who has broken quickselect on purpose will spot it first. The longer argument is in [is coding still worth learning in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Parramatta, Chatswood or Bondi, the same lesson at the same minute Greater Sydney stretches from the coast to the foot of the Blue Mountains, and a live online lesson reaches every part of it without a train or a toll. ### No travel across the city A learner in an apartment near Central and one in a house out west can share the same lesson from their own desks. ### Same words as school A Kindergarten child, a Year 8 student in Stage 4 and an HSC candidate each hear the labels their own Sydney school uses. Lessons are in English. ### A proper first lesson A real task with a real teacher, then a clear suggestion of level, course and weekly time. No card details at any point. ### Groups matched by level Fifteen to twenty learners at the same stage, drawn from Sydney, the rest of Australia and other countries, so every level finds a workable time. ### Twice a week, usually Roughly eight sessions each month in a fixed slot. Holiday breaks and exam fortnights are arranged with the teacher in advance. ### Teachers on India time Sydney is four and a half hours ahead of India time in winter and five and a half ahead once daylight saving starts on Sunday 4 October 2026, so a 4pm Sydney class falls in the late morning of our teachers' day. Daylight saving, written down once NSW clocks go forward at 2am on Sunday 4 October 2026 and back at 3am on Sunday 4 April 2027. India does not change its clocks, so the gap to our teachers moves by one hour on those dates, and lesson times are always confirmed in Sydney time. Fees ## What classes cost in Sydney Three numbers, no add-ons. First class**USD 0** A complete lesson at no cost, ending with a level, a suggested course and a weekly time. Group tuition**USD 100** A month of teaching, usually eight lessons, with fifteen to twenty learners at the same level. Private tuition**USD 150** The same monthly pattern of around eight lessons, with one teacher and one learner. Outside India every family pays in US dollars at a single rate, so the eastern suburbs and Western Sydney get the same bill and no Sydney price list exists. The first invoice follows the trial, once course and slot are agreed; the pricing page covers holidays off, missed sessions and changing from group to private lessons.

The 2021 Census counted 5,231,147 people in the Greater Sydney capital city area, with a median age of 37 against 38 for Australia. ### What is quickselect? Quickselect is an algorithm that finds the value at one position in a list, such as the middle, without sorting the whole list. It splits the list around a pivot and only keeps working on the side that contains the position it wants. ### What is the Sydney bus stop project? Learners take the 885 bus stops OpenStreetMap records in an inner-Sydney rectangle, measure each one's distance from Town Hall station and find the middle distance, 2,781.6 metres, first by sorting and then by quickselect, counting the comparisons each method needs. ### Why did quickselect need 293,709 comparisons once? Because it was given a list that was already sorted and told to pivot on the first element every time. Each split then removed only one value. With a random pivot the same list needed 3,790 comparisons. ### Do you follow the NSW school stages? Yes. We use the stage and year names Sydney schools use, from Kindergarten through Stages 1 to 5 to Year 11 and Year 12, and plan around the NSW school terms and the HSC. ### What time are lessons for Sydney learners? Late afternoon, evening or weekend, picked during the trial and always stated in Sydney time. India is four and a half hours behind Sydney in winter and five and a half behind once the clocks go forward. ### Can lessons pause for school holidays and exams? Yes. Breaks for NSW school holidays, exam weeks and family travel are agreed with the teacher, and the course is planned around the school year. ### Is there a Modern Age Coders centre in Sydney? No, and none is claimed. All teaching is live and online, with no premises anywhere in Australia. A learner needs a laptop or desktop, working sound and a reliable connection, and the contact number shown is an Indian one. ### What do Sydney coding classes cost? The first lesson is free. After that a group place is USD 100 a month for two live lessons a week, around eight a month, with fifteen to twenty learners, or USD 150 a month for the same pattern one to one. Course, format and time are agreed before anything is paid. ### How big are the groups? Fifteen to twenty learners, matched on level, pace and what they want to build rather than on age or suburb. If no suitable group meets at a workable time, one-to-one lessons are offered instead.
