woodpulp, paper, and various other items — chiefly 

 from Canada. These net imports are included in 

 the 12.3 billion cubic feet total in terms of their 

 equivalent volume of roundwood. 



The total volume of wood consumed in 1952 was 

 sufficient to have provided every person with 78 

 cubic feet. Industrial wood comprised about 84 

 percent of the roundwood total and fuelwood 

 accounted for about 16 percent (fig. 113). 



THE BASIC ASSUMPTIONS 



Discussion thus far has been concerned with 

 prospective expansion of the Nation's economy 

 and the general magnitude of raw material re- 

 quirements likely to be associated with economic 

 growth (table 208). The objective has been to 

 provide a framework on whicli to base estimates 

 of the Nation's future demand for timber products. 

 These estimates rest on four major assumptions, 

 the first two of wliicli are held constant: (1) Peace 

 but continued military preparedness, (2) economic 

 prosperity reflected in high-level employment, 

 (3) future population, and (4) the trend in prices 

 of timber products relative to the trend in prices 

 of competing nontimber products.
