About 80% of recent immigrants, possibly higher, are in the typical ages of the workforce (16 to 65). This is higher than the population as a whole, about 70%. There has been a shortfall of about two million new immigrants 2019 – 2022. This suggests a shortfall of about 1.6 million working age persons. Let’s assume that 80% of these would be in employed, or about 1.3 million (the others in school, at home or otherwise not employed).
As if February 2023, there were 10 million job openings, and five million persons unemployed in the workforce – a ratio of 2, compared with a more normal ratio of 1 or lower. Had these 1.3 million recent immigrants been employed, the job openings would have been about nine million and the ratio between openings and unemployment would be about 1.75.
This, of course, assumes that the influx of working immigrants would reasonably match job openings in the short run.
