The relationships between a set of measures of various components of environmental density and perceived crowding are examined in a data set from a sample of residents of a large metropolitan area. While there are meaningful patterns observed among the correlations, the primary finding is the weakness of the relationships between density and crowding. The implications of the weak relationship between objective and subjective measures intended to measure components of the quality of life, of which the present findings are an example, are discussed; the usefulness of subjective measures may lie primarily in their capacity to define what aspects of society should be monitored and included in a system of social accounting.
