2022 Postal Code Areas in Finland
The table in focus forms part of a larger dataset collection pertaining to postal code areas for the year 2022. This table provides a rich set of data, ranging from geographical coordinates to specific details about each postal area. The data is sourced from the 'Tilastokeskus' (Statistics Finland) website, based in Finland.
The table is structured in a way that it offers comprehensive geographical information about each postal area. The information includes the geographic shape data, centroid of the area, and the coordinates of the center. The geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude. This kind of geospatial data is valuable for a variety of analytics purposes, such as visualizing data on a map or performing spatial analysis.
In addition to the geographical details, the table also contains specific attributes of each postal area, such as the area size and the related municipality number and name. These data points can be beneficial for demographic studies, urban planning, or market research, to name a few. For instance, a retailer might use this data to study population density in different areas, which could inform their store location strategy.
Each row in the table is uniquely identified by two special columns: the date when the data was extracted, and the row number from the original data source. This ensures that every piece of data can be traced back to its original source, adding a layer of accountability and reliability to the data.
In summary, this table provides a wealth of data that can be utilized in various ways, depending on the analytical needs. Whether it's for spatial analysis, market research, or urban planning, the extensive data coverage and reliable sourcing make this an invaluable tool for data analytics.
