Comparison of two cluster sampling methods for health surveys in developing countries.
BACKGROUND The Expanded Program for Immunization (EPI) random walk method has been widely used by the World Health Organization and others for rapid cluster sample surveys where an up-to-date household sampling frame is not available. However, it is not a probability sample, does not allow for population movement since the last census, and does not ensure objectivity in household selection or p...
متن کاملSampling Strategy for Agriculture Censuses and Surveys in Developing Countries
Full enumeration agriculture censuses have become less feasible financially and operationally in many developing countries. They had not always lived up to their promise to serve as frame for the intercensal surveys and to provide reasonably accurate benchmark data for small areas. Observed large deviations between the survey and census results point to serious non-sampling errors especially in...
متن کاملA computer simulation of household sampling schemes for health surveys in developing countries.
BACKGROUND Cluster sample surveys of health and nutrition in rural areas of developing countries frequently utilize the EPI (Expanded Programme on Immunization) method of selecting households where complete enumeration and systematic or simple random sampling (SRS) is considered impractical. The first household is selected by choosing a random direction from the centre of the community, countin...
متن کاملDon't spin the pen: two alternative methods for second-stage sampling in urban cluster surveys
In two-stage cluster surveys, the traditional method used in second-stage sampling (in which the first household in a cluster is selected) is time-consuming and may result in biased estimates of the indicator of interest. Firstly, a random direction from the center of the cluster is selected, usually by spinning a pen. The houses along that direction are then counted out to the boundary of the ...
متن کاملLot quality assurance sampling techniques in health surveys in developing countries: advantages and current constraints.
Traditional survey methods, which are generally costly and time-consuming, usually provide information at the regional or national level only. The utilization of lot quality assurance sampling (LQAS) methodology, developed in industry for quality control, makes it possible to use small sample sizes when conducting surveys in small geographical or population-based areas (lots). This article desc...
