2018 Regional Administrative Agencies' Areas (Scale 1:4 500 000)

The table, part of the 'tilastointialueet_avi4500k_2018' dataset collection, carries data pertaining to the 2018 AVI regions in Finland. The data is sourced from 'Tilastokeskus' (Statistics Finland), a reliable source of statistical information in Finland. The table contains several columns that capture various details about each region. Of particular note are '_extract_date' and '_row_number', which respectively indicate when the data was extracted and the row number in the extraction. The combination of these two columns uniquely identifies each row of data.

The dataset contains geographic information captured in columns beginning with 'geom_'. These provide a detailed mapping of each region, including the type of geometry used to represent the region (e.g., multipolygon), the geographic coordinates of the region's center, and a text representation of the region's shape. This geographic data is presented using the WGS 84 coordinate reference system, where the order of the coordinates is longitude first, followed by latitude. This geospatial data can be vital for visualizations and analytics requiring geographical context.

The table also includes other columns capturing the AVI identifier, the name of the region in Finnish as well as in Swedish, and the year of data. This combination of data can be utilized for a variety of analytics, such as identifying trends over time, performing region-specific analyses, or comparing different regions within Finland. For example, an analyst could use this table to study the change in the geographic boundaries of the regions over time, or a data scientist could use the geographic information to train a machine learning model to predict region-specific trends.
