some notable exceptions. Bench marks for State and local government, for example, are based on data compiled by the Bureau of the Census, while data on Federal Government employment is made available by the Civil Service Commission. For railroads, the source is the Interstate Commerce Commission and for water transportation, the Maritime Commission. Projection of estimates.-In general, data showing month-to-month changes in employment reflect the fluctuations shown by establishments reporting to the BLS. However, the usual estimating method is inadequate in finance and service, where a preponderance of small establishments enter and leave the business population at a high rate. A special sampling procedure has been introduced, involving the scientific selection of a sample of cities and a representative list of blocks in these cities. Data obtained from the establishments in these blocks yield substantially better estimates of month-to-month changes in employment in the service and finance industries. For railroads, complete tabulations of reports are available. Presentation of estimates.-The following table presents revised estimates of employees by industry division from 1939 through 1946. A more detailed technical statement of the methodology used in adjusting each series will be available at a later date. Revised estimates of employees1 in nonagricultural establishments, by industry division, January 1939-December 1946 Revised estimates of employee in nonagricultural establishments, by industry division, January 1939-December 1946-Continued Revised estimates of employees 1 in nonagricultural establishments by industry division, January 1939-December 1946—Continued 1 Estimates include all full- and part-time wage and salary workers who worked or received pay during the pay period ending nearest the 15th of the month. Proprietors, self-employed persons, domestic servants, and personnel of the armed forces are excluded. These estimates incorporate the revised estimates adjusted to final 1945 Unemployment Compensation data and, therefore, supersede data shown in mimeographed releases dated prior to April 1947 and Monthly Labor Reviews dated prior to May 1947. Data from January 1939 forward were affected by this revision. Adjusted Manufacturing Series of Employment and Pay Rolls REVISED MONTHLY ESTIMATES of manufacturing production workers and indexes of employment and pay rolls by major industry group from January 1945 to December 1946 are presented below. Hours and earnings were not affected by this adjustment.
