TABLE 9.-Prices received by farmers for meat animals, parity prices, and price received as percent of parity, 1935-39 average-by years, 1947-50; by months, 1950-51 1 Annual prices are unweighted averages of monthly prices. 2 Parity through 1949 is computed from the standard formula then in effect. Parity beginning January 1950 is the effective parity as currently calculated and published. As of January 1950 the new parities exceeded those calculated from the old formula by $3.80 for beef cattle, $1.20 for hogs, and $4.40 for lambs. The new parities reflect average price relationships between meat animals and other farm products during the most recent 10-year period. Source: Bureau of Agricultural Economics.
