However, the chart applies to people who are alive today, and it could be that mortality has knocked down the numbers of the 1957-1960 cohorts.
Gen X is the most immigrant generation ever. Certainly many of the immigrants are PoC. But not all.
In any case 55 is certainly not the peak age for US born. It's got to be older than that.
It's not like there was a step function from Boom to X, vis a vis US vs foreign born.
There had to have been a gradual reduction in the % US born by cohort starting with an early to mid 1950s cohort.
Alternatively, the data behind the chart could be a couple of years. If it is from, say, 2013, then the peak would come from 1957-1958 cohorts.
