In this video tutorial, I illustrate index construction using PCA weights. Then the manipulation is simple: you can use the functions pca or pcamat, and predict in Stata. The construction of a wealth index using PCA (Principal Components Analysis) is discussed, particularly in the context of rural household surveys. I have been able to finalise on the components (there are two components whose eigen values are greater than 1). You will want to take a close look at the proportion of the variance that is explained by your first component.
