I feel you’ve missed the point I was making and assumed I’ve made another. Age number and year number are different. You’re in your first year when your age is not yet 1. You’re in your second year when your age is between 1 and 2.
Years follow numbers as in "this year was the first/second/third year of ", not “this year was the year turned X years old”
Cross the wrong people and you end up not dead, but irrecoverable. Cement shoes, buried alive kind of stuff. Cross a different set of wrong people and you become a labrat. To avoid either scenario, you’ll be in a constant state of “undocumented” or false-documented which will keep you in a pretty consistent state of poverty.
