Abstract:
Trends in the spatial distribution of the population of Finland from 1880 to 1980 are examined using official data from population registers and censuses. "Cumulative maps and graphs and concentration indices were applied as methodological tools, and the administrative communes were taken as the areal units for a chorological matrix." The results show an increasing concentration of the population beginning in the latter half of the nineteenth century, although urbanization levels remain low in comparison with most industrialized European countries. Differences in population distribution by occupation are also considered.
