Strathfield in the Census

A young, apartment-dwelling council area

Headline figures from the 2021 Census QuickStats for the Strathfield local government area, with the state and national figures alongside.

Strathfield council area, 2021 Census
Count	Strathfield
People	45,593
Private dwellings	18,273
Median age	33
Average household size	2.7

How Strathfield differs from NSW and Australia
Indicator	Strathfield	NSW	Australia
Occupied homes that are flats or apartments	59.5% (9,366)	21.7%	14.2%
Occupied homes that are separate houses	34.2% (5,388)	65.6%	72.3%
Aged 15 and over with a bachelor degree or above	44.7% (17,344)	27.8%	26.3%
Residents aged 20 to 24	10.1% (4,601)	6.1%	6.2%

Mostly apartments

Close to six in ten occupied homes were flats or apartments, nearly three times the NSW share.

A large early-twenties group

One resident in ten was aged 20 to 24, against about one in sixteen across the state.

Professional work

Professionals were the largest occupation group, 7,694 people or 33.8% of employed residents.

Census tables are adjusted by small random amounts to protect respondents, so a set of parts rarely matches its published total. Every figure on this page is copied as published, and none is a sum we worked out.

Signature project

Three honest answers to "what percentile is Strathfield?"

Transport for NSW publishes monthly entries for every station. For August 2026 there are 375 entry rows; 16 give no number, only the text "Less than 50".

Percentile rank of a station's August 2026 entries, three definitions (our calculation)
Station and treatment	Strictly below	At or below	Midpoint
Strathfield (653,253 entries), the 16 left out (359 stations)	97.77	98.05	97.91
Strathfield, the 16 kept (375 stations)	97.87	98.13	98.00
Homebush (97,496 entries), the 16 left out	75.77	76.04	75.91
Homebush, the 16 kept	76.80	77.07	76.93
Any one of the 16, kept	0.00	4.27	2.13

Strictly below

The share of stations with fewer entries. Python's bisect_left on a sorted list counts exactly these.

At or below

Adds the station itself and anything tied with it. bisect_right gives this count, and the gap is one station's worth, 0.28 points out of 359.

Midpoint

Below plus half the ties. For the 16 tied stations it lands at 2.13, between the other two answers of 0 and 4.27.

Placeholders that cannot move a rank

We tried replacing "Less than 50" with 0, with 25 and with 49. Every percentile above stayed identical, because each published number is at least 50 and the order never changes. What does change things is leaving the 16 out: Homebush drops by more than a point because 16 stations no longer sit beneath it.

The percentiles, ranks and treatments are our own calculation from the published file; Transport for NSW does not publish percentiles. Station names in the file sometimes contain doubled spaces, so the first step in the code is collapsing them, or "Strathfield Station" fails to match itself across months.

Twenty-three months

Seventh, eighth or ninth, month after month

A single month can mislead. Running the same code over every month in the file shows how steady Strathfield's place is.

Strathfield Station monthly entries, October 2024 to August 2026 (our calculation from the published file)
Measure	Value
Months in the file	23
Rank among stations with a number	7 to 9 in every month
Mean monthly entries	601,741
Lowest month	496,401 (January 2025)
Highest month	682,906 (October 2024)

Even the count of stations with a published number shifts from month to month, from 342 to 364, so a percentile from one month is not directly comparable with another unless the denominator is reported too. A rank, by contrast, needs no denominator, which is why both appear in the code learners write.

Children

Sort a short list of numbers, find where a new one fits, and see why a tie makes the question harder.

Teenagers

Write all three percentile functions, test them against the bisect module, and plot Strathfield over 23 months.

Adults

Handle suppressed values, report denominators, and explain a percentile choice to someone who will act on it.

Transport for NSW, the NSW Department of Education, Strathfield Council and the statistics bureau publish the data we use; none of them is connected with Modern Age Coders, and the analysis is ours.

Coding and AI

If an AI can compute a percentile, why should a Strathfield student learn Python?

Because the AI will pick a definition and a treatment of missing values without telling you, and the answer changes with both.

Ask an assistant for Strathfield Station's percentile and it will produce a number. Whether it left out the 16 stations without a figure, or counted ties as below or at, is usually invisible. Our Strathfield table shows those silent choices moving the result by a third of a point at the top and by more than a point in the middle.

A learner who has written bisect_left and bisect_right by hand knows which question each one answers. They read AI-generated analysis the way a careful editor reads a draft, looking for the decision that was made on their behalf.

In 2026 any tool will hand you a percentile, and the Strathfield learner who asks "of what, and counting what?" is the one whose numbers survive a second look. The longer argument is in why teenagers should still learn to code in 2026.

Delivery

FAQ

Strathfield coding and Python questions

Questions Strathfield parents and adult learners ask before the first lesson.

What is the population of the Strathfield council area?

The 2021 Census counted 45,593 people and 18,273 private dwellings in the Strathfield local government area.

What is a percentile rank?

A percentile rank says what share of a group falls below a value. Definitions differ on ties: some count only values strictly below, some include equal values, and some take the midpoint between the two.

What is the Strathfield percentile project?

Learners take Transport for NSW monthly station entries and compute Strathfield Station's percentile three ways, with and without the 16 stations published as "Less than 50". The answers run from 97.77 to 98.13.

Why does Homebush move more than Strathfield?

Removing the 16 low stations takes 16 values from below every other station. For a station in the middle of the list that is a bigger share of what lies beneath it, so Homebush shifts by about a point and Strathfield by about a tenth.

Does the project say anything about why stations are busy?

No. It measures how a percentile is defined. It makes no claim about why any station has more or fewer entries.

Which Python course suits a beginner teenager?

Usually the Python masterclass for teens, which starts from the first line of code. The free trial confirms it or points to Scratch or maths through coding first.

Can adults learn Python from scratch?

Yes. Adults start from zero in a course built for them and move on to data analysis when ready.

Do you teach in Strathfield in person?

No. Lessons are online and live, and we have no premises in Australia. A computer with a microphone, speakers and a steady connection is enough; our contact number is an Indian one.

How much are Python classes for Strathfield learners?

The first lesson is free. Afterwards a group place costs USD 100 a month for two live lessons a week, about eight lessons, with fifteen to twenty learners, and one-to-one costs USD 150 a month on the same schedule. Course, format and time are agreed before anything is paid.

What decides which group a learner joins?

Level, pace and goals decide it, not age or postcode, and groups hold fifteen to twenty learners. One-to-one lessons are an option if no group time works.
