Quick table on persons reporting Greek ancestry and those born in Greece (separate calculations)
So I ran a quick table looking at persons with Greek ancestry and those born in Greece between 2010 and 2021, using the 5-year 2020 and 2021 estimates of the American Community Survey (ACS).
The numbers reveal a decrease in both categories, with a 6.5% decrease in persons reporting Greek ancestry and a 6.5% decline for those born in Greece.
The above numbers are worth looking into in more detail.
