Wood consumption in Finland in 1938-1939 was studied by investigating the wood consumption of aprroximately 2,000 farms. One of the surveys connected to the investigation studied fireplaces and heating equipment in rural districts, and recorded the types of fireplaces in the farms.
The majority of the rural fireplaces are rather old-fashioned and the technically best equipment are rare. The fireplaces in Eastern and Northern Finland are often more primitive than in Western and Southern Finland.
In Western Finland, where hard bread is common, the baking oven is lit 30-50 times a year. In Eastern Finland, where soft bread is baked, the oven is lit about 200 times a year. The sauna i heated about 40 times a year in the west, and 80 times a year in the east.

The consumption of wood and the value of the wood in the forest manufacturing industry in 1925‒1935 was studied using the official industrial statistics as the main source of data. The annual wood consumption of sawmills, plywood industry, match production, wood-wool industry, spool production, mechanical pulp mills, sulfite pulp mills and sulfate pulp mills was in average 15.6 million cubic meters, of which 4.0 million m3 was pulpwood, 11 million m3 saw logs and 0.44 million m3 veneer timber. The spool production used 163,200 m3, match production 39,900 m3 and wood-wool production 7,900 m3 of wood. When the wood consumption is at its maximum levels, the fellings cannot be increased sustainably. Thus, the sawing cannot be increased from the present level. The growth of pulp industry has created demand for small timber, and in that industry there is room for expansion.

The main source of data was the official industrial statistics in 1911‒1929. The data was complemented with information from other sources, and the figures converted to solid volumes under bark. The wood consumption of wood manufacturing industry in the period varied strongly, being lowest in 1918 (2.2 million m3) and highest in 1927 (18.1 million m3). The wood consumption dropped during the World War I.
The wood manufacturing industry in Finland concentrated on sawmilling industry which has used annually 70‒80% of the wood consumed in the whole wood manufacturing industry. Other sectors of industry using wood were plywood industry, wood-wool industry, spool factories, match industry, mechanical pulpwood industry and pulp industry.

Annual variations in wood utilization makes it complicated to estimate the balance between wood utilization and wood production of forests. According to the article, the balance is unsustainable especially in the private forests in the southern part of Finland. The annual wood utilization of the country was 37.3 million m3 in 1913, and the annual wood production 35.2 million m3, according to a report of a committee that was appointed to find methods to prevent overcutting. The committee suggested legislation to forbid forest devastation. Also the growth of the forests could be increased, if the forests are well managed, the article argues. To prove this, the potential wood production capacity is estimated for the municipalities of Viipuri, Mikkeli and Kuopio, and compared to the present wood production and wood utilization of the area.
