Click here for a data sample
The table, part of the dataset collection 'tilastointialueet_kunta4500k_2021', contains data related to 'Municipalities 2021 (1:4 500 000)', sourced from the 'Tilastokeskus' (Statistics Finland) website in Finland. The data includes information about different municipalities, identified with specific codes and names, and the year of data reference. Moreover, each row in the table is uniquely identified by a combination of an extraction date and a row number, indicating when the data was pulled from the source and the position of the row in the extracted data. A significant part of the data is dedicated to geographic information, providing detailed geospatial data that can be utilized for geospatial data analytics. This geographic data includes polygons, centroids, and center coordinates in the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude. Examples of data analytics use-cases for this table could include studying municipality-specific trends over time, performing geospatial analyses to understand spatial patterns and relations across different municipalities, or using the geographic data to create detailed maps and visualizations.
