Measurement and Mismeasurement of Social Indicators
指出社会指标测量存在陷阱，基于国家总量比较得出结论困难重重，即使有高质量调查数据，可比性和测量问题依然普遍存在，呼吁投资改善数据收集的质量和频率。
Measurement of social indicators is not without its pitfalls, however, and drawing conclusions based on comparisons of national aggregates is fraught with difficulties, especially when data sources are sketchy. The paper in that issue make a compelling argument for investing in improving the quality - and frequency - of data-collection efforts. However, even when good survey data do exist, serious and often quite subtle issues of comparability and measurmenet still abound.
