In an attempt to measure the representativeness of the substitutions, a comparison was made be- tween the substitutions and the interviews which were originally classified as Type A, but were later obtained. For about half the Type A ad- dresses, a completed interview was finally ob- tained. The interviews which were originally Type A but were later completed are very similar to the artificially completed interviews. The Type A substitutions and those originally Type A but later completed differ from the completed interview in that they have slightly more illnesses reported. It appears that the Type A substitutions were prob- ably representative of the interviews not obtained. Post Enumeration Survey INTRODUCTION As a part of the survey technique a subsample of the Survey population was selected and reinter- viewed for the purpose of shedding light on some of the nonsampling variations. This phase, called the Post Enumeration Sur- vey, was conducted concurrently with the Survey from the 12th week through the 52nd final week. *Comprised approximately 1/12 of the total sample: % of the sample area segments and ¥ of the sample ad- dresses in these segments. An interview was conducted for (1) each adult not responding for self originally, (2) one-half of all other household members, including children.
