Coding classes in Hackney

What are the best coding classes in Hackney?

Hackney is the east London borough of Shoreditch, Dalston, Stoke Newington, Clapton, Homerton, Hackney Wick and Stamford Hill, home to 259,146 people at the 2021 Census and to more than 33,000 trees on the public list of trees looked after by councils and other public bodies. A class worth its fee teaches a learner to estimate what they cannot yet see from what they can, and this page does that with Hackney's trees: how many species appear as you look at more and more trees, and a famous formula that guesses how many are still unrecorded. Teachers in India teach live over video, for learners aged 6 to 67, either one to one or in small classes of five to ten sharing a level. The first lesson is free. Group places then cost USD 100 a month; private lessons USD 150 a month.

The Greater London Authority publishes a list of trees maintained by London's councils and other public bodies, with the species of each where it is known. Hackney has 33,085 entries. Walk down a Hackney street and you will soon have seen London planes, silver birches and sycamores; keep walking and new species appear more and more rarely. Ecologists call the graph of that slowing discovery a species accumulation curve, and our learners draw it by sampling the list at random. Then they meet Chao1, a short formula that uses only the species seen once or twice to estimate how many were never seen at all. On the full list it suggests about 255 species where 229 are named. On small samples, learners find it guesses far too low.

Hackney in numbers

259,146 residents and 33,085 listed trees

Every figure below is published by the organisation named, or counted by us from its open data.

Four Hackney numbers
Subject	Number	Publisher or source
People living in Hackney on Census day, March 2021	259,146	Office for National Statistics
Trees in Hackney on the London tree list	33,085	Greater London Authority, November 2025 file
Heritage List entries inside the borough	552: 8 Grade I, 30 Grade II*, 514 Grade II	Historic England data, counted 25 September 2026
Council libraries	9	Hackney Council, read 25 September 2026

Churches at Grade I

Six of Hackney's eight Grade I entries are churches or church buildings, including St Leonard in Shoreditch, St Matthias, St Michael, St Chad and St Columba with its vicarage.

A tower on its own

The old tower of the former Church of St Augustine is listed at Grade I in its own right.

A museum

The building the list names as the Geffrye Museum completes Hackney's Grade I entries.

Hackney Council runs libraries at Clapton, Dalston CLR James, Hackney Central, Homerton, Shoreditch, Stamford Hill, Stoke Newington and Woodberry Down, and lists a community library service too.

The data

Cleaning the list before counting it

Before counting species, learners have to decide what counts as one. The list is honest about what it does not know.

Hackney's 33,085 tree records, by how precisely they are named
How the tree is recorded	Trees	Example
Named to species	21,719	Platanus hispanica, London Plane
Named only to genus	11,181	Prunus, cherry of some kind
Recorded as unknown	185	Unknown Tree Species

A third of Hackney's trees are named only to genus: "a cherry", "a lime", "a maple". Counting "Prunus" as a species would be wrong, because it might hide several. So learners keep only the 21,719 trees named to species, and find 229 species among them. The most common by far is the London Plane, 2,981 trees or 13.7% of the species-named total, followed by silver birch, sycamore, ash and field maple. Most records are the council's own, with a few hundred each from Transport for London and the body that looks after the Olympic Park area.

The London list covers boroughs very unevenly, with over 100,000 trees for one borough and around a thousand for another, so this project never compares Hackney with anywhere else. It is a study of one list and what it can tell us.

Signature project

Estimating the species nobody has recorded

Learners draw a species accumulation curve, then test a formula that estimates what the survey missed.

1. Sample and count

Pick 100 trees at random and count the species; then 500, 1,000, 10,000. Repeat each size 50 times and average. The curve rises fast, then flattens.

2. Singletons matter

Species seen exactly once, and exactly twice, are the clue. Many singletons means many rare species, and probably more that were never seen at all.

3. Chao1

The estimate is the number observed, plus the number of singletons squared, divided by twice the number of doubletons. It is designed as a lower bound.

Species found as more trees are sampled, run 25 September 2026
Trees sampled	Species found, on average	Chao1 estimate from that sample
1,000	130	172 (145 to 204 in 90% of samples)
2,000	157	195 (172 to 226)
5,000	189	217 (198 to 238)
All 21,719	229	255

On the full list there are 24 species represented by a single tree and 11 by exactly two, which lifts the estimate to about 255: perhaps two dozen more species out there than the list names, planted in private gardens, or hidden among the trees recorded only to genus. The small-sample test is the sobering part. From 1,000 trees, Chao1 estimates 172 species, yet the full list already contains 229. The formula is honest about being a lower bound, and learners see exactly how low it can be when a sample is small.

Why this is a lesson AI cannot shortcut

Ask an AI how many tree species grow in Hackney and it will produce a number, perhaps confidently. A learner who has built the accumulation curve and tested Chao1 knows that every such number depends on how much was looked at, what counted as a species, and which estimator was used, and that some estimators always err on the low side. The same reasoning is used for rare words in a language, unseen bugs in software and undiscovered species in the ocean.

Doing it properly

Three decisions learners write down first

Choices made before counting shape every answer that follows.

What is a species?

Records named only to genus are set aside, and the number set aside is reported, not hidden.

Random, repeated

Each sample size is drawn 50 times with a fixed random seed, so anyone can rerun the curve and get the same result.

Say what it estimates

Chao1 estimates species among trees like these, on lists like this. It says nothing about gardens, parks or trees never surveyed.

GCSE biology and maths students can follow sampling, counting and the curve; A-level students can derive why singletons and doubletons carry the information and compare Chao1 with other estimators. The tree records are the Greater London Authority's, compiled from the bodies that maintain the trees; the cleaning, sampling, curves and estimates are ours, computed on 25 September 2026. Modern Age Coders works independently of the GLA, Hackney Council, Transport for London, Historic England and the ONS.

Getting around

Hackney Central, the Overground and a quiet room

Much of Hackney is served by the Overground rather than the Tube. For our lessons, a good connection of a different kind is what counts.

Hackney Central

TfL's open data lists the Mildmay line at Hackney Central.

Stamford Hill to Shoreditch

A learner at the northern tip of the borough and one near Shoreditch can share a class without a single journey.

No one left unrecorded

In groups of five to ten at one stage, the teacher knows every learner by name and by progress.

Hackney among London's boroughs

Hackney is one of London's 32 boroughs. The London page covers every borough and the City, linking each page as it goes live, including Newham to the east and Camden to the west.

Learning ladder

From leaf collecting to estimating the unseen

Where a learner starts depends on what they show us in the free lesson; a school year only hints at it.

Coding and AI

AI can count anything. Why should a Hackney teenager learn to estimate what was never counted?

Because every real dataset is incomplete, and the missing part is often what matters.

AI tools can tally a list in a moment. What they will not volunteer is that a third of this list is recorded only to genus, that the count depends on how many trees you look at, and that the standard estimate of unseen species undershoots badly on small samples. A learner who has run the curve and the estimator themselves knows to ask those questions of any count, including counts produced by AI.

Estimating the unseen runs through ecology, security testing, quality control and language technology. Machines will keep producing counts. People who understand what a count leaves out will keep being needed.

Hackney's streets hold more than 30,000 trees and at least 229 kinds of them. A Hackney learner who can estimate how many more are out there is doing real science on their own doorstep. The longer argument is in why teenagers should still learn to code in 2026.

Delivery

Dalston to Hackney Wick, lessons live

From any corner of Hackney, a lesson starts the moment the video call does.

Learn where you are

All that is needed is a laptop or desktop, headphones and an internet connection steady enough for video.

English Key Stages

Parents hear about progress in the vocabulary of a Hackney school report: which Key Stage, and, for older learners, how it links to GCSE or A level. Every lesson is taught in English.

The first lesson is free

Genuine teaching with a teacher, finishing with a suggested level and course, and no request for card details.

Classes by level

Classmates share a stage rather than a postcode: five to ten of them, from anywhere in the UK or beyond, which keeps a reasonable evening hour available.

Twice a week

A standard week has two evening lessons; the class takes breaks for school holidays and exam season once everyone has agreed.

UK times only

Invitations and reminders show London time, even though your teacher is working from India.

A dense borough, a matched class

Around 259,000 people live in Hackney, and a good class still needs five learners at the same stage free at the same time, so our classes draw from far beyond it.

Fees

Fees for Hackney families

Nothing for lesson one; afterwards a single monthly fee that does not vary between Shoreditch and Stamford Hill.

First classUSD 0

A full first lesson with a teacher, free, ending with a recommended level, course and time.

Group tuitionUSD 100

About eight live lessons a month in a class of five to ten at one stage.

Private tuitionUSD 150

About eight live lessons a month, one to one with a teacher.

Fees for Hackney, like everywhere outside India, are set in US dollars, which is why no pound figures appear anywhere on the site. Money only changes hands once the free lesson is over and a course and a regular slot have been agreed. The pricing page explains pauses, missed lessons and switching between group and private lessons.

FAQ

Hackney families' questions

About the borough, the tree project and how our lessons work.

How many people live in Hackney?

The 2021 Census counted 259,146 usual residents in the London Borough of Hackney, in ONS table TS001.

Where does the tree data come from?

From the Greater London Authority's list of trees maintained by local authorities and other public bodies, published on the London Datastore. The November 2025 file has 33,085 entries for Hackney.

What is the most common tree in the list?

The London Plane, Platanus hispanica: 2,981 trees, or 13.7% of the trees named to species. Silver birch, sycamore, ash and field maple come next.

What is the Chao1 estimate?

A formula for estimating how many species exist, including unseen ones, from the number observed and the numbers seen exactly once and exactly twice. For Hackney's list it gives about 255, against 229 species named.

Why did Chao1 guess too low on small samples?

It is designed as a lower bound, and a small sample contains few of the rarer species. From 1,000 trees it estimated about 172 species, but the full list already names 229.

When do Hackney learners have lessons?

Once the free lesson has placed the learner, we name a class at that level with a seat available and its fixed weekly evening, written in UK time; the teacher is in India.

What equipment is needed?

A computer with sound and a reliable connection. The tree project needs Python and one free download from the London Datastore.

Is there a Modern Age Coders centre in Hackney?

No. There is no Hackney centre and no premises anywhere in the UK, because every lesson is live online. A learner needs a computer with sound and a stable connection, and our phone number is Indian.

What do coding classes in Hackney cost?

The first lesson is free. After that, a group place costs USD 100 a month for two live lessons a week, about eight a month, with five to ten learners, and one-to-one teaching on the same timetable costs USD 150 a month. Nothing is charged until the course, format and time are agreed.

How are the groups made up?

By level, pace and goals rather than by age or neighbourhood, with five to ten learners at one stage. Where no group fits the learner's week, one-to-one lessons are offered.
