Based on administrative and survey data as well as data-based assumptions about the bounds on alien address reporting, this study provides estimates of the lower and upper bounds for the cumulative net emigration rates, by country and area of origin, of the FY1971 cohort of legal immigrants to the United States as of January 1979. The merged data indicate that the cumulative net emigration rate for the entire cohort could have been as high as 50 percent. Canadian emigration was probably between 51 and 55 percent. Emigration rates for legal immigrants from Central America, the Caribbean (excluding Cuba), and South America were at least as high as 50 percent, and could have been as high as 70 percent. Emigration rates for Koreans and Chinese could not have exceeded 22 percent over the same period.
基于行政和调查数据以及关于外国住址报告界限的基于数据的假设，本研究提供了截至1979年1月，1971财年合法移民到美国的队列按原籍国和地区划分的累计净移民率的下限和上限估计值。合并后的数据表明，整个队列的累计净移民率可能高达50%。加拿大的移民率可能在51%至55%之间。来自中美洲、加勒比地区（不包括古巴）和南美洲的合法移民的移民率至少高达50%，并且可能高达70%。在同一时期，韩国人和中国人的移民率不可能超过22%。
