The project behind the map
About IndoEuroMap
Explore European places through their classified name records. See the patterns, read the method, and understand the limits.
Content updated · By Bernat Sampera
Area-level results. Published methods. Clear data limits.
Our purpose
Make the data easier to explore.
A city total can hide differences between the records collected in each area. IndoEuroMap brings those records into one map, with a profile for each covered area.
The map groups names into broad algorithm categories. You can explore the results, check the coverage, and read how each figure was made.
The source has limits. A record connects a name to a place, but it does not show where that person lives. Read every percentage as a share of classified records.
What we do
From a place to a clearer view of its data.
Six ways to explore the map and understand what is behind it.
Explore places on a map
Move from a European overview to a country, city, or neighbourhood. See the areas covered by the available records.
Find a city
Search the city list and filter by country. Open a place to see its map and available area profiles.
Read the category breakdown
See broad algorithm categories as shares of classified online records. Each area combines records from selected places within its boundary.
Check data coverage
Read the coverage notes with the results. Record density helps explain the sample, but it does not measure accuracy.
Follow the method
Read how names become area totals. The methodology page explains the rules, sources, and limits behind the figures.
View area totals
The public website receives combined area data and map boundaries. It does not display individual records or individual name labels.
Who it is for
For people who want to look closer.
People curious about cities
Explore how the classified records differ between places. Use the map as a starting point for questions about the sample.
Writers and researchers
Find area summaries and inspect the method. Any use of a figure needs its source, sample limits, and record context.
People working with maps and data
Examine how a place-based sample becomes a map. Check the boundaries, category definitions, and gaps before drawing conclusions.
How it works
Four steps from records to a map.
- 1
Select places
The process starts with selected public places in a city. The location of each place determines its area.
- 2
Classify signals
Our algorithm assigns broad categories from name patterns and other signals. Records that do not meet the active rules stay out of the published shares.
- 3
Combine the records
The pipeline limits repeats and combines counts by area. Small counts are pooled. Areas need enough classified records for a result.
- 4
Publish the area profiles
The website displays aggregate shares and coverage notes. Current shares use no scaling to official population figures.
Who is behind it
The people and the story.
- Our story
- IndoEuroMap started with a personal interest in cities and the patterns within them. The aim is to make those patterns easier to explore through maps, while explaining where the data comes from and what it can tell us. The project grows through continued work on the data, the method, and the site.
- Behind the project
- IndoEuroMap is an independent passion project. Its creator builds and maintains the site, develops the data tools, and reviews feedback. An interest in cities, maps, and data drives the work.
Our approach
Four principles behind the map.
Shares need context
A category does not establish ethnicity, nationality, residence, or culture. Records can include visitors and repeats.
Missing data stays visible
Low-data areas, suppressed values, and measured zero mean different things. A gap in the sample must stay visible on the map.
The method belongs beside the result
A figure needs its rules and limits. The error rate of current exported shares is unknown.
Public results stay at area level
The private pipeline stores individual records and name scores. The website shows combined results, without individual records.
How the project is funded
IndoEuroMap is fully bootstrapped. Its creator covers development, hosting, and data processing costs. There are no external investors. It is a passion project, built out of curiosity and a wish to make the data easier to explore.

Common questions
Before you explore.
What is IndoEuroMap?
IndoEuroMap maps classified online records from selected public places in Europe. It combines those records into area profiles and shows their shares on a map.
What does a percentage on the map mean?
It is a share of the classified records used for that area. It is not a share of residents. Records that cannot be classified under the active rules do not enter those shares.
Can the map show who lives in a neighbourhood?
No. The selected place determines the area, not the home of the record author. Authors can be residents or visitors. A category cannot establish a person's identity or residence.
How accurate are the figures?
The error rate of the current exported shares is unknown. Place selection, visitor activity, repeat records, and classification can affect the result. Data coverage measures record density, not accuracy.
Why do some areas have no result?
An area may have too few classified records or no accepted data. Low-data and missing-data states are not measured zero. Some small values are also suppressed.
Does the website show individual data?
No. The public website receives aggregate area profiles and map boundaries. The private pipeline stores individual records and name scores, but the website does not display them.
Where can I read the full method?
The methodology section explains the process, including country differences. Read it with any map result you use.
Reports and data
Need a city report or a dataset?
We offer prepared city reports and a licensed dataset for research use. Both use area aggregates only, with no individual records or individual name labels.
