We use data from the 1970, 1980 and 1990 census public-use files to assess the impact of newly identified Indians on the educational attainment of American Indians who were at least 25 years old in 1970. We test the hypotheses that this impact was limited to metropolitan areas and to states with small Indian populations. We find that educational attainment for American Indians rose sharply between 1970 and 1990 and that changes in racial identification were an important component of this increase in 1980 but not in 1990. Increases in educational attainment were concentrated in metropolitan areas and occurred in states with large and small Indian populations.
我们使用1970年、1980年和1990年人口普查公共使用文件中的数据，来评估新识别出的印第安人对1970年时至少25岁的美国印第安人教育程度的影响。我们检验了这样的假设，即这种影响仅限于大都市地区以及印第安人口较少的州。我们发现，1970年至1990年间美国印第安人的教育程度大幅提高，而且种族身份的变化在1980年是这一增长的重要组成部分，但在1990年并非如此。教育程度的提高集中在大都市地区，并且在印第安人口多和少的州都有出现。
