Abstract:<\/strong><\/span> A \u201csmall area\u201d or a \u201csmall domain\u201d often refers to a small geographic area such as a county, census tract or school district, but that need not always be the case. For instance, in a survey pertaining to a group, cross-classified by age, sex and and ethnicity, even a relatively large geographical area may have very few samples. Thus a small area refers primarily to an area where the sample collected from a survey is not adequate to meet the desired precision. This unreliability of direct small area survey estimates is often due to the fact that the original survey was targeted to achieve accuracy at a higher level of aggregation. Due to limited resources, the same survey data needs to be used at a lower level, resulting in the said inadquacy of the sample size. This makes it imperative to \u201cborrow strength\u201d from similar other areas to increase the effecive sample size and attain the prescribed accuracy. The resulting estimates, usually referred to as \u201cindirect estimates\u201d require explicit, or at least implicit use of models.
\nThe need for small area estimates is felt in these days by both the public and private sectors. Such estimates are often mandated by the Legislature at the national and\/or the state level. Small Area Income and Poverty Estimation (SAIPE) is one such example. Demand from the private sector has also increased rapidly, because business decisions, especially for small businesses, very often rely on local socio-economic conditions.
\nMy talk will be an attempt to trace the evolution of small area estimation, with a modest beginning essentially in the seventies, but with a very rapid growth, especially from the nineties onwards. I will try to trace some of the salient small area estimation methods. I am, however, aware that my talk will fall short of a complete updated account as new and novel small area estimation methods are emerging everyday.<\/div>\n<\/td>\n
