B. Comparisons of U.S. installed computer systems with Federal computer

systems by dollar value.

Charts 9, 10 and 11 show graphically the dollar value of Federal computer systems compared with the dollar value of U.S. installed computer systems. The figures for Federal computer systems are based on the totals from the GSA charts, "Computer Systems by Purchase Price Range," in recent inventories and on information obtained from Alvin Krakow for the other years. The figures for the U.S. installed computer systems are from International Data Corporation's category, "$Billion Value in Use."

The percentages of the $ value of Federal computer systems for the years FY70-FY75 (Figure 12) has declined in these six years but not as significantly as the numbers of computers (shown in Section III A).
