The number of migrants to the United States from Africa has grown exponentially since the 1930s. For the first time in America's history, migrants born in Africa are growing at a faster rate than migrants from any other continent. The composition of African-origin migrants has also changed dramatically: in the mid-twentieth century, the majority were white and came from only three countries; but today, about one-fifth are white, and African-origin migrants hail from across the entire continent. Little is known about the implications of these changes for their labor market outcomes in the United States. Using the 2000-2011 waves of the American Community Survey, we present a picture of enormous heterogeneity in labor market participation, sectoral choice, and hourly earnings of male and female migrants by country of birth, race, age at arrival in the United States, and human capital. For example, controlling a rich set of human capital and demographic characteristics, some migrants-such as those from South Africa/Zimbabwe and Cape Verde, who typically enter on employment visas-earn substantial premiums relative to other African-origin migrants. These premiums are especially large among males who arrived after age 18. In contrast, other migrants-such as those from Sudan/Somalia, who arrived more recently, mostly as refugees-earn substantially less than migrants from other African countries. Understanding the mechanisms generating the heterogeneity in these outcomes-including levels of socioeconomic development, language, culture, and quality of education in countries of origin, as well as selectivity of those who migrate-figures prominently among important unresolved research questions.
自20世纪30年代以来,从非洲移民到美国的人数呈指数级增长。在美国历史上,出生在非洲的移民的增长速度首次超过了来自其他任何大陆的移民。非洲裔移民的构成也发生了巨大变化:在20世纪中叶,大多数是白人,且仅来自三个国家;但如今,约五分之一是白人,非洲裔移民来自整个非洲大陆。对于这些变化对他们在美国劳动力市场结果的影响,人们知之甚少。利用2000年至2011年的美国社区调查数据,我们呈现了一幅关于按出生国、种族、抵达美国时的年龄和人力资本划分的男性和女性移民在劳动力市场参与、行业选择和小时收入方面存在巨大异质性的图景。例如,在控制了一系列丰富的人力资本和人口特征后,一些移民——比如那些来自南非/津巴布韦和佛得角的移民,他们通常持就业签证入境——相对于其他非洲裔移民获得了可观的溢价。这些溢价在18岁以后抵达的男性中尤为显著。相比之下,其他移民——比如那些来自苏丹/索马里的移民,他们最近才抵达,大多是作为难民——的收入远低于来自其他非洲国家的移民。理解这些结果中产生异质性的机制——包括原籍国的社会经济发展水平、语言、文化和教育质量,以及移民者的选择性——在重要的未解决研究问题中占据显著地位。
