Fascinating post and superb research. As you mention, it needs to be followed, particularly in any downturn. I'm reminded of the work of anthropologist Michael Kearney. He points out that even such things as border patrols function not so much to apprehend illegal migrants as to force them to accept low-paying jobs while not claiming benefits accorded to other laborers. He cited the example of migrant Mixtecs, who walk through the mountains in winter to find work and who, because of their work ethic, are desired by American employers. They don’t understand why the Migra (border patrol) seek to apprehend them, forcing them to work harder and faster before they are apprehended and forcing them to take whatever work at whatever wages they can. But, as Kearney indicates, that is exactly the point of the Migra; it is not intended to stop migrants from coming into the United States to work; rather it functions to discipline them to work harder and accept low wages
Sure! NAICS numbers are six-digit hierarchical code, where they start with the broad category with the first numbers and then narrow with more numbers consistent.
Examples are easier. So all construction starts with 23, construction of buildings all start with 236, and residential building construction is 2361. (We're just focused on the four-digits of specificity.)
The monthly jobs numbers has all four digits. The Census, which gives us noncitizen numbers, has a mix.
The algorithm tries to match at 4-digits, if it fails it tries to match at 3, and then at 2. e.g. Census has only 23 for NAICS information, so all the different four digit construction job categories end up there, since they all start with 23.
Very interesting work. To me, it is evidence that new immigration policies partially explain job growth decline in CES.
Horrific policy on its own. Also a blow to the supply-side of the labor market.
Thanks for posting!

Can you provide more details on the “cross walk algorithm”

Adding this to a footnote.
