This sampling method is an example of two-stage area sampling, which involves dividing the population into clusters or areas, and then randomly selecting a sample of clusters/areas, followed by randomly sampling units within each selected cluster/area. In this case, the city of Flint is divided into blocks (clusters) and a sample of 100 blocks is randomly selected, followed by the random selection of 4 households within each of the selected blocks. This method allows for greater efficiency and cost-effectiveness compared to one-stage area sampling where all households in all blocks are selected, and it also takes into account the clustering effect within the population.
