Dozens of empirical research have discovered that immigration advantages American employees. Even immigrant employees with little formal training have, with some exceptions, been discovered to have negligible results on the wages of equally educated employees.
As a part of Brookings Workforce of the Future initiative’s ongoing efforts to determine immigration insurance policies that profit American employees, we current a brand new perspective on the position that immigrants play within the U.S. economic system. Utilizing the “complementarity index,” we present that immigrant employees are broadly complementary to natives, each as a result of immigrants work in occupations that serve an unusually wide selection of industries, and likewise as a result of immigrant-intensive occupations usually complement different jobs. Acknowledging this complementarity is crucial provided that present tendencies in occupation progress indicate that the immigrant workforce will grow to be more and more central to the U.S. economic system within the coming years.
In Determine 1 every dot represents an occupation. The vertical axis measures the share of employees in that occupation that had been born overseas, utilizing Census information from 2019. The horizontal axis tracks our personal “complementarity index,” which measures the extent to which every occupation enhances all others. The upper the index, the extra that employees within the occupation are prone to gasoline demand for different jobs.

The logic of our complementarity index is that an occupation is taken into account complementary to different occupations for 2 causes: first, whether it is current in lots of industries, in impact influencing the best way items and companies are produced all through the economic system; and second, if inside an business its employment share grows or shrinks in tandem with different occupations, indicating that its use is tightly linked to the usage of different employees. Formally, the measure captures the share of industries wherein any two occupations had been each current collectively and concurrently grew or shrank over time. For instance, we discover that the complementarity between “meals and beverage serving employees” and “cooks and meals preparation employees” is 0.49, a comparatively excessive worth that signifies that the 2 occupations had been used collectively in 49 p.c of U.S. industries and, on the similar time, that their employment shares had been positively correlated.
The general complementarity index (the horizontal axis of Determine 1) is then the easy common of all these pairwise complementarities for every occupation. As an example, “Workplace and Administrative Help Employees” and “Monetary Specialists” are two of essentially the most complementary occupations, reflecting each their pervasiveness within the economic system and the truth that any explicit occupation is prone to be reliant on administrative and monetary assist.
Whereas recognizing that there could also be many causes for these noticed correlations, the patterns within the determine counsel that thousands and thousands of immigrants work in occupations which can be central to the remainder of the workforce, thereby supporting thousands and thousands of American jobs. The truth is, Determine 1 signifies that almost all of essentially the most immigrant-intensive occupations are above common on this index.
Furthermore, the focus of immigrants in occupations which can be central to the U.S. economic system would be the case properly into the longer term, as many of those extremely central occupations are projected to be among the many quickest rising jobs over the subsequent few years, as Determine 2 exhibits. Within the determine, the horizontal axis exhibits the Bureau of Labor Statistics’ projected employment progress for every occupation for the interval 2020-2030, whereas the vertical axis measures the share of foreign-born employees in every occupation in 2019.

The occupations within the upper-right quadrant correspond to jobs which can be each immigrant intensive and quick rising (the dotted line marks the common worth in each cases). As an example, “house well being and private care” occupations—which embody nurses and different well being professionals—will add over a million employees over the subsequent few years, and roughly 25 p.c of employees in these jobs had been foreign-born, as of 2019.
A serious problem for policymakers is figuring out the best worth insurance policies. Our complementarity index addresses this by figuring out particular elements of the immigrant workforce that create important and widespread advantages for U.S. employees.
Taking the 2 figures collectively, we see that there are a handful of occupations which can be immigrant-intensive, fast-growing, and that even have excessive total complementarity with the remainder of the economic system in keeping with our measure above. A couple of of those are “motorcar operators,” “meals preparation employees,” “materials transferring employees,” and “constructing cleansing and pest management employees.” Every of those jobs requires little formal training however serves as a significant hyperlink alongside a variety of business manufacturing chains.
A serious problem for policymakers is figuring out the best worth insurance policies. Our complementarity index addresses this by figuring out particular elements of the immigrant workforce that create important and widespread advantages for U.S. employees. Accordingly, the index can function one foundation for figuring out the elements of the economic system that might profit most from focused immigration reforms.
