The number of the next, or fourth, household is deter- 

 mined by adding the sampling rate to the number of the first 

 refusal (28 / 10 = 38). An interview is obtained here which 

 completes the required number for this district with the ex- 

 ception of household number 18, which v/as not at home. The 

 enumerator calls back the next evening and completes the 

 interview at number 18. 



If the random number, or first household interviewed in 

 this illustration had been 6 or under, 5 rather than U house- 

 holds would have been interviewed. For example, with a random 

 number of 5, the households interviewed would have been 5, 15, 

 25, 35 and Z,5.
