Haarlemmermeer today

A lake bed with 166,978 people on it, and the fastest growth in this series

The national register held 166,978 people on 1 January 2026, in 70,473 households averaging 2.31 people, the largest average of any city in this series, on 197.21 square kilometres of land inside 206.31 of territory: 838 to the square kilometre. In 1995 the count was 109,654, so the municipality has gained 57,324 people in thirty-one years, a rise of 52 percent.

Families, not students

26,339 residents are under fifteen, 16 percent, and 21,425 are between fifteen and twenty-five; 41,801 are between twenty-five and forty-five and 30,581 are sixty-five or over. Only 23,034 households hold one person, 33 percent, the lowest share in this series. Haarlemmermeer is where people move when they want a house and a garden within reach of two cities.

Fifty-five primary schools, eleven secondary

55 primary establishments teach 13,532 pupils and 11 secondary establishments teach 7,394. That ratio is what a spread-out municipality of villages looks like: a primary school in each place, and secondary schools concentrated in Hoofddorp and Nieuw-Vennep with a bus for everybody else.

Named after water that is not there

The municipality carries the name of the lake. The lake was pumped dry on 1 July 1852 after a ring dike whose construction began in May 1840 and took eight years. Around 800 million cubic metres of water were moved by three steam pumping stations, the Leeghwater, the Lynden and the Cruquius.

The municipality and its largest town have different names

The municipality is Haarlemmermeer; its main town is Hoofddorp, which had 79,650 residents in 2023 and was named in 1868 after being founded in 1853, the year after the drainage. Anyone searching for the town by the municipality's name, or the reverse, is looking for the wrong thing, and this page uses both names deliberately throughout.

Where the learners are

Hoofddorp, Nieuw-Vennep and the villages of the polder

The statistics office counts 25 woonplaatsen in the municipality; the municipality's own entry says it recognises 31 kernen. Both counts are published, both are kept here, and only five of those places have populations in the sources this page read.

Hoofddorp, 79,650 in 2023

The main town and the seat of the municipality, founded in 1853 on the drained bed and named in 1868. Just under half the municipality lives here, with the station, the hospital and most of the secondary schools.

Nieuw-Vennep, 31,595 in 2023

The second town, south-west of Hoofddorp on the other side of the polder, with its own station and its own secondary provision, and far enough from the first that families think of them as separate places.

Badhoevedorp, 14,455 in 2023

Counted with Nieuwe Meer in the source. North-east, closest to Amsterdam, and the village most affected by the airport and the motorways that serve it.

Vijfhuizen, 4,865 in 2023

Counted with Nieuwebrug. North-west towards Haarlem, on the ring dike itself, small enough that an after-school club of any kind is a matter of who volunteers.

Rijsenhout, 4,330 in 2023

South-east by the Ringvaart and the greenhouses. A village school, a sports club, and a bus to Hoofddorp for everything else, including anything a teenager might want to learn in the evening.

The other twenty, or twenty-six

Zwanenburg, Lisserbroek, Cruquius, Abbenes, Buitenkaag, Beinsdorp, Burgerveen, Weteringbrug, Lijnden, Rozenburg, Boesingheliede and the rest. Their populations are not published in the sources here, and together with the five named above they must account for the municipality's 166,978.

Every one of them gets the same class at the same hour, and no village boundary has ever decided which group a learner joins.

Verified local facts

Every figure, its office, and the two things this page refuses to state

The national count, the municipal entry, the drainage record, the airport, and the depth that no source gives.

The municipal count

Statistics Netherlands, provisional, 1 January 2026: 166,978 residents; 70,473 households for 2025 averaging 2.31 people, 23,034 of them single-person, 33 percent; 26,339 aged under fifteen; 21,425 aged fifteen to twenty-five; 41,801 aged twenty-five to forty-five; 30,581 aged sixty-five and over; 55 primary establishments with 13,532 pupils and 11 secondary with 7,394; total area 20,631 hectares, land 19,721; density 838; 25 woonplaatsen, 18 wijken and 97 buurten; 109,654 residents in 1995, a rise of 57,324, which is 52 percent.

The municipality, described

Its own entry: 166,996 residents on 1 January 2026, 18 more than the national figure for the same date, both kept; 206.31 square kilometres in total, 197.48 of land and 8.83 of water, against 197.21 of land nationally, both kept; mayor Marianne Schuurmans-Wijdeven; main town Hoofddorp; the municipality recognises 31 kernen, against the 25 woonplaatsen counted nationally, and both counts are printed here.

The five villages with figures

From the same entry, all dated 2023: Hoofddorp 79,650; Nieuw-Vennep 31,595; Badhoevedorp including Nieuwe Meer 14,455; Vijfhuizen including Nieuwebrug 4,865; Rijsenhout 4,330. Those five total 134,895, which leaves 32,083 of the 2026 municipal figure spread across everywhere else, on two dates that do not match.

The drainage

The lake finally fell dry on 1 July 1852. Work on the ring dike began in May 1840 and took eight years. About 800 million cubic metres of water were pumped, by the steam stations Leeghwater, Lynden and Cruquius, with further stations at Spaarndam, Halfweg and Gouda in the wider system.

The airport

Schiphol lies inside the municipality at 3.35 metres below the national datum, and registered 68.8 million passenger movements in 2025. A passenger movement is an event, not a person: one return trip is two of them and a transfer is two more, so that figure cannot be divided by anything to yield a number of travellers.

What is not here

No depth for the polder or the former lake below the datum was found in any source read for this page, and none is stated. The 4.05 metres computed below is an arithmetic exercise about a division, clearly labelled, and is not offered as the depth of anything.

Modern Age Coders has no connection to the municipality, the airport or any school named here and claims none. They are on the page because a page that says it teaches Haarlemmermeer should be able to say what Haarlemmermeer is standing on.

Signature project

How deep was the lake? Build the division, then find the assumption that breaks it

Two published quantities, one obvious division, and an answer to a question nobody asked.

1. Do the obvious thing

About 800 million cubic metres of water were pumped out and the municipality has 197.48 square kilometres of land. Divide and you get 4.05 metres. It looks like an average depth, it is the right order of magnitude for a Dutch lake, and it is arrived at honestly from two published figures.

2. Name the assumption

That division is only the lake's depth if every cubic metre pumped was standing in the lake when the pumps started. The pumps ran for years, rain fell on the whole surface throughout, and water seeped in under the ring dike continuously. So the 800 million is a volume moved over time, not a volume held at a moment, and the two are different physical quantities.

3. See which way the error runs

Every extra cubic metre of rain or seepage raises the total pumped without deepening the original lake, so the naive figure is an upper bound rather than an estimate. And the denominator is wrong in the other direction: the modern municipality is not the same shape as the historic lake, so 4.05 metres is a number produced by two mismatched inputs and answers neither question cleanly.

One division, and what each part of it actually is
Element	Published value	What it really measures	Effect on the answer
Water pumped	about 800 million cubic metres	a volume moved over several years	includes rain and seepage, so it is too large
Area	197.48 square kilometres of land	the modern municipality, not the historic lake	the wrong footprint, in an unknown direction
The division	4.05 metres	an upper bound on average depth at best	not a depth, and not stated as one
Depth below the datum	not published in any source read	the quantity actually wanted	left unstated on this page

Dividing two real numbers always gives an answer; only sometimes is it the answer to your question

A volume divided by an area has the units of a length, and units are the weakest possible evidence that a calculation means anything. What makes the result a depth is a physical assumption, that nothing entered or left the system between the measurement of the volume and the moment being described, and here that assumption is plainly false: it rained for three years while the pumps ran. The habit worth carrying away is to write the assumption down beside the formula, in words, before running it, and then to ask which direction each violation pushes the answer. A learner who does that will produce fewer confident numbers and far more useful ones. The 4.05 metres was computed before this paragraph was written, from two published figures, and is presented as a demonstration of a flawed division rather than as a fact about the lake.

Reliable pipeline

Five habits for any figure you get by dividing one thing by another

Cost per customer, litres per hectare, incidents per thousand hours, storage per user: every one is a quotient resting on an assumption about what stays constant. Practised on the water under the learner's own street.

When a quotient is about to become a conclusion
Stage	Rule	What it prevents	What it gives you
Check the units, then ignore them	Matching units is necessary and nowhere near sufficient	Metres accepted as a depth	A reason to keep asking
Write the assumption in words	State what must be true for the quotient to mean what you want	A hidden closed-system claim	A sentence a colleague can dispute
Ask over what period	Distinguish a stock at a moment from a flow over time	A three-year total read as a standing volume	Two quantities kept apart
Match the denominator	Confirm the divisor covers exactly the thing the numerator came from	A modern boundary used for a historic lake	A ratio about one object
Sign the error	Say which way each violated assumption pushes the result	A wrong number with no direction	An upper or lower bound you can use

For younger learners

A tray of water and a jug. The child empties the tray into the jug and works out how deep the water was, then does it again while somebody drips more water into the tray from a bottle. The second answer is bigger and the tray never changed. That is the entire lesson, and it takes ten minutes.

For teenagers

The division in Python with the assumption written as a comment above it, then a small model: add a rainfall rate and a pumping duration and watch the implied depth fall as the inflow rises. The stretch: what rainfall over three years would account for the whole difference between a plausible lake depth and 4.05 metres?

For adults

The same treatment on a per-unit figure from work. Cost per customer computed from an annual cost and a month-end customer count is exactly this error, and adults nearly always find one in a deck they have presented themselves.

The population, household, area, school, village, drainage and airport figures come from the offices and entries named beside them. The 4.05 metres, the 134,895 and the 32,083 are this page's arithmetic on those published figures and are labelled as arithmetic wherever they appear.

Python Automation Course Data and AI Analytics for Non-Programmers (Excel, Sheets, Power BI)

Coding and AI

An AI will divide 800 million by the area and hand you a depth. Why should a child in Hoofddorp learn to refuse it?

Because the arithmetic is correct, the units come out right, and the result is not a depth.

Ask a tool how deep the Haarlemmermeer was, give it the volume pumped and the area, and it will produce a number with metres after it. Units are a trap here rather than a check: a volume over an area is always a length, whatever the volume was really measuring. What the tool has no way of knowing from the numbers is that the pumping ran for years against rain and seepage, and that the modern municipal boundary is not the shape of the historic lake. Those are facts about the world, not about the digits.

So the learner writes the assumption above the formula and then tests it. That is not a coding skill in the narrow sense; it is the habit of asking what has to be true for a calculation to answer the question that was actually asked. A thirteen-year-old in Nieuw-Vennep who has done this once with water will do it at twenty-three with cost per customer, and will notice that the year in the numerator and the month in the denominator do not match. Tools will keep getting better at dividing. They will not start knowing what your two numbers were measuring.

The case for a Haarlemmermeer child learning to code in 2026 is therefore not about polders. It is that a quotient is a claim about the world dressed as a fact about numbers, that the claim is usually unstated, and that writing it down before running the division is a habit best acquired on something local, physical and genuinely unresolved. The longer argument is in why a child should still learn to code in 2026.

Delivery

Live classes for twenty-five villages on one flat polder

Rijsenhout to Zwanenburg crosses the whole municipality on straight roads with the wind across them, and Vijfhuizen looks to Haarlem while Badhoevedorp looks to Amsterdam. The lesson reaches all of it without anybody moving.

No polder roads in the dark

Class happens at the kitchen table in Abbenes, Lisserbroek or Hoofddorp at a fixed weekly hour, whatever the wind is doing across the fields.

The lesson is English; the school words are not

Instruction happens in English. Terms a Dutch school uses stay Dutch on purpose, so a teacher will say groep, havo, vwo or profielkeuze rather than reach for an equivalent, and no translating is done in either direction.

What the first hour produces

Work that shows the real level, the name of a course that follows from it, and a slot in the week, all arranged without payment details.

Grouped by stage, not by village

Two learners at the same point work together whether one is in Cruquius and the other in Nieuw-Vennep; two at different points do not.

A fixed slot twice weekly, around the northern holidays

The rhythm is two lessons every week, which is eight in most months. School holidays here follow regio Noord, as they do across Noord-Holland, and any weeks a family will be away are written into the schedule before a time is confirmed.

Winter puts an extra hour between the two countries

Because India never adjusts its clocks and the Netherlands does, the teacher sits four and a half hours ahead of the polder from late October and three and a half from late March. Usable slots begin once the school day ends and run into the evening, and Saturday and Sunday are open all day.

A municipality where the aircraft never stop and the schools are spread thin

Eleven secondary establishments serve 25 villages, so most teenagers here already travel to school. Adding an evening journey on top of that is what stops many families from starting anything, and it is precisely the cost a live online class removes.

Fees

FAQ

Haarlemmermeer coding class questions

The municipality, its villages, its lake, the teaching and the terms.

Is this page about Haarlemmermeer or Hoofddorp?

Both, because they are not the same name for the same thing. Haarlemmermeer is the municipality, with 166,978 residents on 1 January 2026; Hoofddorp is its largest town, with 79,650 in 2023, founded in 1853 and named in 1868. Families searching for one and finding the other are in the right place either way, and the page uses both names deliberately.

How deep was the Haarlemmermeer?

No source read for this page publishes a depth, and none is stated here. About 800 million cubic metres were pumped out, and dividing that by the municipality's 197.48 square kilometres of land gives 4.05 metres, which is not the answer: the pumps ran for years against rain and seepage, so the volume includes water that arrived after the work started, and the modern boundary is not the shape of the historic lake. Working through why that division fails is the project on this page.

Which villages does the class reach?

All of them. The national count gives 25 woonplaatsen and the municipality says it recognises 31 kernen; both figures are published and both are kept here. Hoofddorp, Nieuw-Vennep, Badhoevedorp, Vijfhuizen and Rijsenhout have published populations, and the rest, from Zwanenburg and Lisserbroek to Abbenes and Boesingheliede, do not.

Is any of this taught in Dutch?

It is not. English is the working language of every lesson. What stays Dutch is the school vocabulary, groep and havo and vwo and profielkeuze, because those are the words a child meets on a timetable. A Dutch-medium version of the course does not exist.

What time are classes for a family in Haarlemmermeer?

From late March the teacher runs three and a half hours ahead of the polder, and from late October four and a half, because only one of the two countries shifts its clocks. In practice that leaves everything between the end of school and mid-evening, plus the whole of Saturday and Sunday. A single weekly time is settled in the free lesson and then left alone.

Does living near Schiphol make any difference?

Not to the class. The airport registered 68.8 million passenger movements in 2025 and sits at 3.35 metres below the national datum inside this municipality, but a lesson that arrives through the connection is unaffected by any of it. The page mentions the figure mainly to note that a movement is an event and not a person, so it cannot be divided into a count of travellers.

What is in the free lesson?

Everything starts by locating what the learner can already do and then setting one task a step beyond it. Children often get a tray of water and a bottle dripping into it. Teenagers get a division they may not run until the assumption behind it is written out. Adults bring a per-unit figure from work whose top and bottom cover different periods. The hour finishes with a named course, a starting point, a weekly time and the dollar price, none of which costs anything to arrange.

Is there a Modern Age Coders classroom in Haarlemmermeer?

No, and none is claimed in Hoofddorp, near Schiphol or anywhere in the Netherlands. Lessons are live online and need a laptop or desktop, working audio, a current browser and a stable connection. The telephone number on this page is Indian and is described as such.

What do Haarlemmermeer coding classes cost?

The first lesson is free. Group tuition is USD 100 a month for two live lessons a week, normally eight in the month, in a group of five to ten. Private tuition is USD 150 a month, one learner with one teacher at the same frequency. Course, format, recurring time and availability are confirmed before payment.

How many learners are in a Haarlemmermeer group?

Between five and ten, matched on level, pace and goal rather than on age, school or village. Private tuition is one learner and one teacher. If no group at the right level is running, the family can take private tuition or wait for the next one to form.
