摘要:Although continued attention has been given to the general study of "community," we still lack a consensus. operational definition . Such an absence impedes development in this area of stud y. Because authors have used different areal conceptualizations, knowledge is, at best, case specific. This paper reviews the problem most often associated with aggregation of data. namely, aggregation bias. and considers some additional problems not usually associated with aggregation. The review serves as a prelude to a discussion of community research methodology which, at present, is beset with potential aggregation problems. Interpretation and possible implications of these findings are advanced.
