The 85 X 85 matrix in Table 4.4a contains a wealth of information useful to the chemical professional. Tables 4.6-4.8, which illustrate several important aspects of the sales patterns found in the United States, are typical examples. There is a wide variation among industries in the proportion of total output going to final demand. Some industries (e.g., construction [11 and 12], food and kindred products [14], apparel [18], furniture and fixtures [22 and 23]) sell most of their products directly to final demand. Other industries (e.g., nonmetallic minerals [9 and 10], lumber and wood products [20 and 21], metallic ores mining [5] metal containers [39]) sell practically all their output to intermediate consumers. The CPI and related industries fit mostly in the latter category (Table 4.6).
