Aberdeen today

A working-age city on the north-east coast

Figures from National Records of Scotland's first results for the 2022 census. Counts are rounded to the nearest hundred and printed as released.

Aberdeen City council area, Scotland's Census 2022
Measure	Aberdeen	Scotland
Usual residents, rounded	224,000	5,436,600
Usual residents in 2011	222,793	Not compared
Households, rounded	109,500	Not compared
Households in 2011	103,371	Not compared
Aged 20 to 24, rounded	18,900	337,000
Share aged 15 to 64	68.2%	64.6%
Share aged 65 and over	17.1%	20.1%
Residents per square kilometre	1,207.1	69.8

Working age

People aged 15 to 64 made up 68.2% of Aberdeen's residents in 2022, above Scotland's 64.6%, while 17.1% were 65 or over against 20.1%.

More homes than before

Households rose to about 109,500 from 103,371 in 2011, a faster change than the population, which moved from 222,793 to about 224,000.

Compact city

At 1,207.1 residents per square kilometre, Aberdeen is far denser than the Scottish average of 69.8, though well below Glasgow.

National Records of Scotland also reports that 21.3% of Aberdeen households had dependent children in 2022. Our learners here range across every stage: a P4 pupil in Cults making a first animation, an S4 student in Bridge of Don working towards National 5 Computing Science, or someone in their twenties in Torry learning Python for work, each in a group of five to ten at their own level.

Granite and learning

A university from 1495 and a building of granite

From the University of Aberdeen's own history.

1495

The University says it was founded that year, and that King's College became the UK's fifth university, welcoming its first students in 1505.

1593

Marischal College was founded. Its medieval buildings were mostly replaced in the 1830s, and the University says its 1906 facade makes it the second-largest granite building in the world.

Five laureates

The University counts five Nobel laureates among those associated with it, including Frederick Soddy, Chemistry in 1921, and J J R Macleod, Medicine in 1923, for the research leading to insulin.

We have no connection with the University of Aberdeen. We tell its story because this is a city that has been recording, naming and measuring things for five centuries, and the project on this page is about doing that economically: how few bits can hold the name of every road, school, hill and suburb in Aberdeen and still answer questions about them.

Where the names come from

Ordnance Survey publishes Open Names as free data under the Open Government Licence. Filtered to Aberdeen City and with postcodes left out, it lists 3,324 named features, 3,170 of them distinct: 2,916 named roads, 74 sections of road, 52 primary schools, 42 suburban areas, 34 hills and more besides.

Signature project

Every place name in Aberdeen, in six kilobytes

A Bloom filter stores a set as a wall of bits. It can say a name is definitely absent, or probably present, and it is never wrong in the first direction.

A Bloom filter holding Aberdeen's 3,170 named places, tested against 8,588 names from Glasgow, Edinburgh and Dundee
Bits per name	Memory	False positives	Measured rate	Textbook rate
4	1.5 KB	1,562	18.19%	14.69%
8	3.1 KB	437	5.09%	2.16%
10	3.9 KB	196	2.28%	0.82%
16	6.2 KB	28	0.33%	0.05%
A plain set of the same names	about 300 KB	0	0%	Not applicable

1. Hash to bits

Each name is turned into several positions in a long row of bits, and those bits are switched on. Nothing else is stored: the names themselves are never kept.

2. Ask a question

To test a name, look at the same positions. If any bit is off, the name was certainly never added. If all are on, it is probably present, and might be a collision.

3. Measure both errors

Every one of the 3,170 real names was found, at every size: not a single false negative. The false positives were counted against names from three other cities.

Errors that only point one way

A Bloom filter cannot lose a name. If it says no, the answer is certain, which is why real systems use one as a cheap first gate: a browser checking a web address against a huge list, a database avoiding a slow disk read, a spellchecker holding a dictionary in a fraction of the memory. Whatever it lets through is checked properly afterwards, so a false positive costs time, never correctness.

The measured rates sit above the textbook formula, and the reason is worth more than the formula. The standard equation assumes perfectly independent, evenly spread hash values. Real place names share endings, hundreds of them finishing in Street, Road, Place or Crescent, and our two 32-bit hashes are not the ideal the theory imagines. A learner who only quotes the formula reports 0.05% when the honest answer, measured on real names, is 0.33%.

Trading memory for certainty

Five habits for probabilistic data structures

Learned on place names, used afterwards on caches, spam filters, duplicate detection, blocklists and any system too big to hold exactly.

Using a Bloom filter responsibly
Habit	What it looks like	What it prevents
Know which error is possible	State plainly that false positives happen and false negatives cannot	Treating a probable yes as a certain one
Size it for the data	Choose bits per element and hash count together, not separately	A filter that is either huge or useless
Measure on real keys	Test with names from outside the set, not random strings	A rate that only holds for tidy made-up data
Check it back	Send every probable yes to the exact lookup behind it	A wrong answer reaching the user
Say what you cannot do	Remember you cannot list the contents or remove an item	Designing a feature the structure cannot support

The last habit surprises people. Because only bits are stored, a Bloom filter cannot tell you what is inside it, and removing a name would switch off bits that other names rely on. That is the price of the compression, and it is why learners build one and a plain set side by side, then decide which the job actually needs.

Younger learners

A row of boxes ticked by a simple rule, and the discovery that two different words can tick exactly the same boxes.

Teenagers

The Open Names file filtered to Aberdeen in Python, a Bloom filter written with bit operations, and both error rates measured against theory.

Adults

Caches, deduplication and membership tests at work, sized deliberately and always checked against the exact source.

We are not connected with Ordnance Survey, National Records of Scotland or the University of Aberdeen. Open Names is published under the Open Government Licence and the census figures are public; the filters, counts and rates are our own work.

Learning ladder

From ticking boxes to a Bloom filter

The age bands are a rough guide; the free lesson finds the real starting point.

Ages 6 to 10

Ticks and guesses

Marking boxes by a rule, spotting when two words mark the same ones, and seeing why that causes a wrong yes.

Problem Solving and Computational Thinking for Kids Mental Maths for Kids

Ages 11 to 13

Sets and membership

Storing words in a list and then a set, timing the difference and counting the memory used.

Python and AI for Kids Maths Through Coding

Ages 14 to 18

Bloom filters in Python

Bit operations, several hashes per key, and both kinds of error measured on real place names.

Problem Solving for Teens Python for Teens

Ages 18 to 67

Memory budgets at work

Probabilistic structures in databases, caches and pipelines, chosen with their guarantees understood.

Coding and AI

A computer can hold every place name in Britain. Why should an Aberdeen teenager build a Bloom filter?

Because scale turns memory into a design decision, and the trade needs understanding.

On a laptop, 300 kilobytes is nothing, and an AI assistant will rightly suggest a set. Multiply by every name in the country, or by every address a service has seen, and the same question gets expensive. A learner who has built a Bloom filter knows what can be given up safely, what cannot, and how to measure the difference rather than guess it.

These structures also sit inside the systems that train and serve AI. Huge text collections are deduplicated with hashing filters, databases skip disk reads with them, and network services screen requests with them before doing real work. They are a clear, small example of the rule that runs through the whole field: you can buy speed and space with a little uncertainty, provided you know exactly which way the uncertainty points.

So an Aberdeen teenager should still learn to program in 2026, in a city that has been naming and measuring itself since 1495: the interesting questions are no longer whether a computer can store something, but what it costs and what it gives up. The longer argument is in why coding is worth learning in 2026.

Delivery

Old Aberdeen, Cults or Bridge of Don, from home

Aberdeen weather makes a short journey feel long; a live online lesson removes it.

North or south of the Dee

A learner in Dyce and another in Kincorth can share one lesson without either crossing the city.

Primary, secondary and national levels

Primary 1 to 7, S1 to S6, then National 5, Higher and Advanced Higher: lessons use the names Aberdeen schools use, and teaching is in English.

A first lesson that teaches

The free session covers a real task and ends by recommending a level, a course and a weekly time. No card details are needed.

Matched by level

Groups of five to ten learners at the same stage, drawn from Aberdeen, elsewhere in Britain and overseas, so every level finds a workable hour.

Two lessons each week

A fixed pair of weekly slots, roughly eight lessons a month, with holiday and exam breaks agreed with the teacher in advance.

India keeps one clock

India Standard Time never shifts, so Aberdeen runs four and a half hours behind it in British Summer Time and five and a half behind in winter, which keeps after-school and evening lessons inside the teaching day.

Across the north east

Families in Westhill, Inverurie or Stonehaven join exactly the same groups, because every lesson is online and groups are formed by level rather than address.

Fees

Aberdeen lesson fees

A free first lesson, then one monthly price.

First classUSD 0

A complete lesson at no cost, ending with a level, a recommended course and a proposed weekly time.

Group tuitionUSD 100

About eight live lessons a month in a group of five to ten learners at one level.

Private tuitionUSD 150

About eight live lessons a month with a teacher working only with your learner.

Every family outside India pays the same US dollar fee, so Rosemount and Mannofield pay alike, and we publish no prices in pounds. Nothing is billed until the free lesson has settled a course and a slot; the pricing page covers pauses, missed lessons and moving between group and private teaching.

FAQ

Aberdeen coding class questions

What Aberdeen families ask us most.

How many people live in Aberdeen?

Scotland's Census 2022 counted about 224,000 usual residents in Aberdeen City, rounded to the nearest hundred, compared with 222,793 in 2011, in about 109,500 households.

How does Aberdeen compare with Scotland?

In 2022, 68.2% of Aberdeen residents were aged 15 to 64 against 64.6% nationally, 17.1% were 65 or over against 20.1%, and there were 1,207.1 residents per square kilometre against 69.8.

What is a Bloom filter?

A compact way of testing whether something is in a set. It can answer definitely not, or probably yes, using only a row of bits, and it never mistakenly says no about something that was added.

How small can it be?

Aberdeen's 3,170 named places fit in 6.2 kilobytes with a false positive rate of 0.33% in our test, or 1.5 kilobytes at 18%. A plain set of the same names uses about 300 kilobytes.

Where do the place names come from?

Ordnance Survey Open Names, published as free data under the Open Government Licence. Filtered to Aberdeen City and excluding postcodes, it lists 2,916 named roads among 3,170 distinct names.

How old is the University of Aberdeen?

The University says it was founded in 1495, with King's College welcoming its first students in 1505, and it counts five Nobel laureates among those associated with it. We are not connected with the University.

When are Aberdeen lessons held?

Weekday afternoons and evenings or weekends, at a UK time agreed during the free lesson. India runs 4.5 hours ahead of Aberdeen in summer and 5.5 hours ahead in winter.

Is there a Modern Age Coders centre in Aberdeen?

No. There is no Aberdeen centre and no premises anywhere in the UK; every lesson is taught live online. Learners need a computer with sound and a steady connection, and our phone number is Indian.

How much do Aberdeen lessons cost?

The first lesson is free. After it, a group place is USD 100 a month for two live lessons a week, about eight a month, with five to ten learners, and one-to-one lessons on the same pattern are USD 150 a month. Course, format and time are agreed before any charge.

How are Aberdeen groups formed?

By level, pace and aims rather than age or postcode, with five to ten learners at one stage. If no group meets at a suitable time, we offer one-to-one lessons.
