The 1951, 1950, and 1949 "Average number of employees" is based on reported employment totals for the pay roll periods ended nearest the 15th of March, May, August, and November. For 1947, an average based on the mid-month employment for 12 months was used.

3The percentage standard errors shown in this column indicate the differences that can be expected between the estimates and comparable complete canvass totals, because of sampling fluctuations. The estimates will differ from the complete totals by less than:
(i) The percentage shown: approximately 2 times out of 3.
4The totals shown for 1951, 1950, and 1949 include employees separately reported at central administrative offices and auxiliary establish
5To maintain comparability with 1951 and 1949 employment estimates, the United States, Division, and State employment totals for 1950 have been adjusted to include employment at plants not in production during the year. Employment at these plants is estimated at 82,000 during 1950. In addition, the 1950 estimates for a few States have been revised for other reasons and, therefore, differ from previously published data. "The totals shown for 1947 represent employment data only at operating manufacturing establishments.
7The data for North Dakota and South Dakota have been combined because of the high standard errors associated with the survey estimates for each State.
