Who is postal code data suitable for?
You benefit from the data material in these cases:
- You want to visualize numbers in a map view
- Compiling the Statistics Finland’s data seems difficult
- You need the boundaries of the postcode areas in longitude and latitude
- You need the centroids of the zip code areas in longitude and latitude
- Representation of postal code areas in the software product
How does the data differ from Statistics Finland’s open material?
Statistics Finland’s material contains figures by postal code area on these topics:
- Population structure
- Level of education
- Disposable income
- Household size and life stage
- Buildings and apartments
- Jobs by industry
- Residents’ main activity
Statistics Finland’s material is difficult to find and compile, according to many. In addition, the map points are expressed in ETRS-TM35FIN format that most modern business reporting software does not support.
Summary of the information added to the further processed material for each zip code area:
- The name of the municipality
- Postal code boundaries as multi polygons
- The centroid of the postal code area
The conversion of Statistics Finland’s coordinate and polygon format into longitude and latitude circles requires programming skills. The work takes even an experienced creator hours.
Simply compiling the data into a single file can prove to be time-consuming.
Data of the boundaries of postal code areas
Postal code boundaries are expressed in MultiPolygon format in this sellable dataset.
In practice, this means that each postcode area is represented by one or more polygons. For example, the postal code area of Naantali, located in the archipelago, consists of nine separate areas.
The coordinates are as latitude and longitude in the standard geographic coordinate system. Longitudes between -180 and 180 and latitudes between 0 and 90 for both south and north.
Postal code dataset metadata
You can find the original descriptions of Statistics Finland’s variables here .
Here is the list of added variables:
| Column | Explanation |
|---|---|
| multi_polygon | Postal code area boundaries in MultiPolygon format as standard map coordinates. |
| longitude | The x-coordinate of the center of the postal code area in degrees. |
| latitude | The y-coordinate of the center of the postal code area in degrees. |
| kuntanimi | The municipality name in which most of the buildings in the postcode area are located. For example, Tampere or Jyväskylä. The original data only has the municipality code, eg 837 or 179. |
The data includes all 3026 postal code areas in Finland from 310 municipalities. There are 8088 separate polygons, so on average almost 3 per postal code area. This is explained mainly by the scattered Turku archipelago.
Polygons are defined with a total of 725 661 coordinate points. On average, one polygon therefore consists of about 90 coordinate points.
