Paavo Postal Code Areas Extending to Sea Regions, 2015

The table in focus, originating from Finland's Statistics Bureau website (Tilastokeskus), is a constituent of the dataset collection known as 'postialue_pno_meri_2015'. Its data is primarily aimed at providing information about the Paavo postal code areas, extending to sea regions, for the year 2015. The table is a treasury of geographic and demographic data, with a rich set of columns providing various details.

The special columns '_extract_date' and '_row_number' serve a unique purpose. The former captures the date when the data was extracted, while the latter reflects the row number for the data extracted on that specific date. Together, these two columns establish a unique identity for each row in the table.

The table also holds a collection of 'geom_' prefixed columns, which offer geographic details. For instance, there are columns that provide geospatial information in geojson and geotext formats, the type of geometry, and the centroid of the geometry. Other columns give the x and y coordinates of the center of the geometry. These geographic coordinates are presented using the WGS 84 coordinate reference system, with longitude appearing first, followed by latitude.

Further, there are columns that offer additional details about the data, such as the area's name, its size, and its postal code.

This table, with its abundance of geographic and demographic data, is a valuable resource for data analytics. For example, it could be used to conduct geospatial analyses, study population distributions, or map postal code areas. It could also be leveraged in market research studies to understand the demographics of various regions, or in logistics planning for optimizing delivery routes.
