Procedxire for Selecting Establishments in the Survey 



The Public Eating Place Survey sample includes h,630 

 retail establishments in the following kinds of business: (1) eating 

 places (2) drinking places (3) drug and proprietary stores and (U) 

 hotels serving meals. The sample allocated to each of these kinds of 

 business was approximately proportionate to the estimated value of their 

 sales of meals (from the 19kS) Census of Business). The sample for the 

 first three kinds of business was drawn as a subsample from the sample 

 used by the Bureau of the Census for the Monthly Retail Trade Report 

 while the sample for hotels was drawn from the sample used by the Bureau 

 of the Census in the 1953 annual report (which in turn was derived from 

 the monthly sample materials) . Since the sample for all kinds of 

 business was based directly or indirectly on the monthly sample, this 

 is described briefly below: 



Group I Stores 



These stores are located in Census primary sampling units. 

 The primary units are combinations of counties which hawe been grouped 

 into 230 strata comprising the entire United States, From each stratum, 

 one primaiy unit was selected as a sample primary unit. Within these 

 230 primary sampling units stores are selected in two wgys: 



1. Stores which has sales above a specified criteria 

 in I9I48 were taken with certainty (Current Mailing 

 List stores). 



2, Stores located in a sangile of land segments within 

 the primary sampling unit. These land segments 

 were selected with knovm probability and designated 

 in 12 panels (one for each calendar month) so that 

 in general, a different group of land segments is 

 for each month. 



The results of this stratification and subsampling is that the 

 stores in item one above are selected viith probability equal to the 

 probability of selection of the primary sampling unit and the stores in 

 item two above are selected with a probability of 1 in 200, 



Group n Stores 



Jill organizations which reported operating 11 or more estab- 

 lishments in I9I18 were taken regardless of location.
