I need to select North Africans and Middle Easterners in each MSA if there are at least 10 of them. However, I need help with regard to weighting process. Am I supposed to weight my sample first and select the cases later or select my cases from the unweighted sample and use weight while analyzing my data? For instance, if I don’t use weight in the first place, I would have 58 MSAs that have at least 10 North Africans. If I weight the sample first, the number of MSAs that contain North Africans triples! If anyone could clarify this problem for me, I would appreciate it. Thanks in advance.
