Kokkuvõte	Social Protection Targeting is the set of methods used to decide who receives a transfer or safety-net benefit when resources are too scarce to cover everyone. Synthesised in the World Bank reviews of David Coady, Margaret Grosh, and John Hoddinott (2004) and the practical handbook of Grosh and colleagues (2008), it spans means testing, proxy means testing, community-based targeting, geographic targeting, and categorical targeting. Every method trades off two errors — including the non-poor (leakage) and excluding the poor (undercoverage) — and the analyst's job is to choose, calibrate, and combine mechanisms so that, given the budget and administrative capacity, benefits reach the intended population as accurately as possible.	Asset index construction builds a proxy for household wealth or socioeconomic status from observable possessions — durable goods, housing quality, and access to utilities — when reliable income or consumption data are unavailable. The dominant approach, popularized by Deon Filmer and Lant Pritchett in 2001, applies principal component analysis (PCA) to a set of asset variables and uses the first principal component as a set of weights, producing a single wealth score for each household. The method underlies the wealth quintiles reported in Demographic and Health Surveys and many other household surveys across low- and middle-income countries.
