time you should have interviewed or contacted for 

 interview, the number of households called for in 

 your answer in 3, above, cr in some instances one 

 additional household. For refusals and people not 

 at home see instructions which are given later. 



(b) If the answer you obtained, in 3, above, is more 

 than 6, divide the total number of households in 

 your district by 6, and round to the nearest whole 

 number. The answer you get will be the sampling 

 rate for this district. If this new sampling rate 

 differs from the one given on the block listings 

 of consumer households, the number of the first 

 household to be interviewed will also change. In 

 this situation determine the number of the first 

 household to be interviewed by using the table of 

 random numbers supplied to you. The number of the 

 2nd. household will be determined by adding the 

 sampling rate to the number of the first household. 

 Likev/ise, the 3rd. household will be determined by 

 adding the sampling rate to the number of the 2nd. 

 household — etc. The total number of households 

 interviewed in the districts where this procedure 

 is used will always be six. 



In using the table of random numbers, start at 

 the left hand side and read dovm the columns. As a 

 random number is used in selecting a household to be 

 interviewed, strike it off the list. The next random 

 nimber in the sequence will be used in determining 

 the first household to be interviewed in the next 

 district where you may be working. If a number on 

 the random table exceeds the total of the households 

 in the district, disregard it and proceed to the 

 next random number. The disregarded numbers should 

 be marked off the list and not used at all. All 

 numbers will be taken in sequence. You should ne\'5r 

 go back to an unused number. Several tables of 

 random numbers will be given to you. Be sure to use 

 the one which corresponds to the sampling rate for 

 the district. 



B. Refusals 



In the event that a consumer refuses to participate in 

 the survey, write the address on the form given to you for 

 this purpose and turn it in to your supervisor. After a 

 refusal, go to the next household to get a replacement for 

 the refusal. For example, if the refusal was number 17, go 

 to 18 to get the replacement. If 17 and 18 both refuse, go 

 to 19 and so on until you get the replacement. To get the 

 nximber of the next household to interview, after an alternate 

 household has been interviewed, add the sampling rate to tlie
