The national atlases of Finland: The fifth edition, its background and structure

Jaatinen describes four published folios of the fifth edition of Atlas of Finland. Forestry (234), issued first in 1977 because statistics were available and forestry held a central economic position, uses consistent colours for tree species and compound diagrams combining species composition and ownership. Population (210) includes maps automatically generated from 1970 census records: the 1:1 million population-density map uses 2.5-km grid squares, while a small-scale map calculates density through partly overlapping circles of approximately 9-km radius. Agriculture–Special Branches/Fisheries (232–233), published in 1980, covers reindeer husbandry, hunting and game, fishing, bee-keeping and fur farming. Its 22 fish-catch cartograms use colour shades to indicate stepped symbol scales; catches are mapped using the Baltic international grid of approximately 2,500-km² squares. Public Administration (311) contains 44 pages of two-colour maps and figures, including 60 maps of administrative divisions and an analysis of administrative centres and their spheres of influence. Jaatinen presents this folio as both a reference source and a basis for planning administrative structures.
