[Some practical problems arising from the use of the PGE/ERAD method in Morocco].

[Article in French]



This paper describes the problems arising from the multiround survey designed to study fertility and mortality undertaken in Morocco between July, 1972 and June, 1973. 84,000 people were in the sample; 36,000 from urban centers. Each sampling unit was broken up into 1500 persons which represents 300 households. It was found that the standard error increases when the size of the sampling unit diminishes. This was true both for the number of births and the number of deaths. By taking into account the cost, the weekly working time of an enumerator, the supervision and the distance within a sampling unit the author concludes that small sampling units of about 1,000 persons are more suitable for this method. Part time "resident" enumerators and full time "external" enumerators were employed in the survey. Comparison between the 2 categories shows that in order to get good registration of demographic events, the external enumerators are better off for registering the births in the urban areas and the deaths in rural areas. Resident enumerators did better at births registration in rural areas and deaths in urban areas. To insure that all households in a sampling unit are under control, each household, inhabited or uninhabited, should be numbered, and the interval between visits of the enumerator should not exceed 3 months. Strict control and permanent supervision of the enumerators is necessary to make certain that all households are visited and their members listed. In enumerating events at health centers, only those belonging to the housholds of the sampling units were recorded. Suggestions for better control include choosing supervisors from among the best enumerators with field experience and daily visits to enumerators to check questionnaires. Migration is not suitable for study using the multiple round survey because the sampling units need to be larger. Difficulties occur when comparison is made between results of different visits. For Morocco the comparison between the survey and the registration show that 71% of births were recorded during the registration against 74% during the survey, in both rural and urban areas. The recorded percentage of deaths was 62% for the registration, 57% for the survey.
