nativeness

noun

1. (countable, uncountable)The state or condition of being native.

   “And yet it was not quite true to say there were almost no natives, nativeness being a relative matter, and many others considered themselves native to this country, by which they meant that they or their parents or their grandparents or the grandparents of their grandparents had been born on the strip of land that stretched from the mid-northern Pacific to the mid-northern Atlantic, that their existence here did not owe anything to a physical migration that had occurred in their lifetimes.”
