Toward a Methodology for Estimating Temporary Residents
讨论了临时居民的定义和估算难题，评估了多种数据来源和估算方法的优缺点，对开发估算方法的前景做了判断。
Abstract Most population statistics for states, counties, and cities refer to permanent residents, or persons who spend most of their time in an area. At certain times, however, many states and local areas have large numbers of temporary residents who exert a significant impact on the area's economy, physical environment, and quality of life. Typically, very little is known about the number, timing, and characteristics of these residents. This study discusses the problems of defining and estimating temporary residents, focusing on the strengths and weaknesses of a number of data sources and estimation techniques. It closes with an assessment of the potential usefulness of developing methods to estimate temporary residents.
