In addition to statistics of dollar values, three types of index numbers are presented. These are unit-value (price), quantity, and (total) value indexes. Unit-value and quantity indexes have been constructed according to the Fisher formula. Weights from the preceding year and the current period are used and the indexes chained into a continuous series. Value indexes are direct ratios of current values to average values in the base period. A more complete explanation of the calculation of the index numbers can be found in appendix A. All commodities in U.S. export and import trade have been grouped into one of five economic classes as follows: Crude foods. Products for edible use (by man or animals) which have not been substantially processed after sale by the farmer, fisherman, rancher, or other primary producer. Manufactured foods. Processed forms of crude foods, edible and refined oils, and oilcake and meal. Crude materials. Products of farms, forests, fisheries, and mines which are for nonfood use and which are unprocessed by manufacturing. Semimanufactures. Manufactured materials in the early stages of proc- essing. Finished manufactures. Highly processed bulk materials and products manufactured from semimanufactures or other finished products. Appendix B, table B-1 shows the coverage of U.S. indexes by economic class. Percentages indicating the relative importance of economic classes and sub-groups in the indexes are shown in table B-2 for exports and table B-3 for imports. For recent years and quarters, tables 1-8 of this publication also contain data for "manufactured goods." This grouping includes commodities which, according to the Standard International Trade Classification of the United Nations, are classi- fied as chemicals (Section 5), manufactured goods grouped chiefly by material (Section 6), machinery and transport equipment (Section 7), and miscellaneous manufactured articles (Section 8).

Methodology of Constructing U.S. Foreign Trade Indexes 21 Value Index Numbers (a) Annual indexes are ratios of annual values for an aggregate to values for the same aggregate in the base year, 1967. Algebraically, the index number can be expressed as: V\% x 100 (1) where p. q. represents the dollar value in a current year for the most detailed commodity permitted by the commodity classification system; p q represents the dollar value for the same commodity in the base period 1967. The summation sign (I) indicates addition of the values to any level of aggregation desired. For published index numbers, summations are made for five com- modity groups as indicated. (b) Quarterly indexes are simple arithmetic averages of monthly index numbers. (c) Monthly indexes are computed using term (1) above with the following modifications: p. q. values in the numerator of the term are monthly dollar values for a commodity. Values representing p qin the denominator are monthly averages of the base year 1967. Unit-Value (Price) Index Numbers (a) Annual indexes of unit values are computed by a "link" method utilizing the Fisher formula. A relative change is computed showing the relationship between the current year and the previous year unit values for an aggregation of commodities. This change is then linked to a unit-value index in the previous year for the same aggregate. Algebraically, the computation is expressed as: 1 (Ri / ) o v l/o 7 (2) In formula (2), I is the unit-value index number to be calculated for an aggregate in the current year. I is the index number for the same aggregate in the previous year. This index is on a 1967 base. R. , is the average l/o b change in the unit value between the current year and the previous year, computed as follows: R l/o , ZP lV. IP l q I = ] ^o% (3) In formula (3), the subscript "1" relates to values in the current year; the subscript "o" to values in the previous year. The left term under the square root sign is a Laspeyre's relative utilizing previous year quantity weights (q Q ). The right term is the Paasche relative utilizingcurrent year quantity weights (q.). The actual formula used for calculating the annual unit-value index numbers by electronic computer is: (4) In formula (4), I. and I are defined as in formula (2). Subscripts "1" (3). The variables 1 and "o" are defined as in formula 'p." and"p * are average unit values in their respective periods. These are derived by divid- ing a dollar value by a comparable quantity figure (pounds, tons, bushels, number of units, etc.). V is the value of all commodities in the previous year, i.e., total exports or total imports. Calculations within parentheses are performed at the 6-digit level of the commodity classification of the index number system. For exports, this represents a combi- nation of one or more commodity or commodity-country totals, commodities having been classified originally by the most detailed Schedule B classification. For imports, the 6-digit classification of the index system combines one or more commodity or commodity-country totals from the Tariff Schedules of the United States Annotated (TSUSA). The summation indicated by the symbol {%,) is carried out at the 5-digit level and at more aggregative levels, as needed. In formula (4), the ratios jX- are utilized only for p o covered commodities, i.e., predesignated 6-digit clas- sifications. Noncovered commodities are excluded from this ratio because of either of the following: (a) quantity data are not available from Bureau of the Census records and, therefore, values such as "p, " and "p " cannot be derived; (b) quantity data are available but the com- modities consist of such a mixture of unlike items that their ratios p,/p are often erratic. *r o For such noncovered commodities, price movements are most often replaced by price movements of covered commodities in the same 5-digit commodity groups which is accomplished by adjusting upward, where P o q o p l q l necessary, ratios such as -= — and -r 7 — . o o ment is shown by the illustration in table A, This adjust- 22 Data measuring the extent of coverage are shown in appendix B. In formula (4), for some important commodities, the ratio p,/p ("unit value relative") is replaced by the term "adjusted unit value relative." This is expressed as follows: Pl/P p l^o (5) p* is the average unit value for the In term (5), current period shipments developed from a regression equation p* - a + bx. The value "x" is the average unit shipping weight for the commodity in the current period. The value p>\ is the average unit value for the earlier year shipments, from the same regression equation except that "x" is the average unit shipping weight of the commodity in the previous year. The coefficients "a" and "b" are computed by a weighted least-squares method using average unit values as the dependent variable, y; average unit- shipping weights as the independent variable, x. In computing the coefficients, the following types of units of observation are utilized: I- -At the commodity level, data by month for the latest available 4 years. II- -At the commodity-country level, data for the latest year. Ill- -At the commodity-transaction level, data for the latest year. (Method III has been used for very large units such as aircraft exports.) (b) Quarterly indexes of unit value are derived by dividing a quarterly value index number by its com- parable quarterly quantity index number and multiplying the quotient by 100. (c) Monthly indexes of unit value are computed by utilizing formula (4) with the following modifications: I. is the index number to be calculated for an aggregate in the current month. The subscript "1" attached to p's and q's relates to monthly data. The constant V in the right bracket under the square root sign is a monthly average of total exports or imports in the preceding year. Table A.

Quantity Index Numbers (a) Annual indexes are derived by dividing an annual value index by its comparable annual unit value index and multiplying the quotient by 100. (b) Quarterly indexes are simple arithmetic averages of the separate monthly quantity indexes for the same aggregate of commodities. (c) Monthly indexes are derived by dividinga monthly value index by its comparable monthly unit-value index and multiplying the quotient by 100. All index numbers are developed from data tapes furnished by the U.S. Bureau of the Census and proc- essed by electronic computer by the staff of the Automatic Data Processing Operations Division, Office of Organi- zation and Management Services, Office of the Secretary. 23 Appendix B.
