why no nativity A? if the requirement is just living abroad for 1 year to belong to those 2M then why should there not be type A people in there too. plus, someone who was born in greece lived in greece for let's say 12 years, so he is not type A native, then moves away for a few years and comes back doesn't really have an origin from abroad imo.
the nativty types are many,
nativity type A is considered as permanent Greek from Hellenic continuity, parental, educational, homeland.
anyway,
the article is clear, as it says,
we speak that 18.8% of Hellas were not permanent citizens before,
an example for instance, are the ones who live in Germany, and on Crimaia etc
in Germany there are 2 kinds of Greeks, the omogeneia, and the migrants, the first are considered permanent living abroad, the migrants who have work less time than the requested time still considered Greek, the migrants that work more time than requested are also considered permanent to abroad,
on the other side Crimaea, N Epirus, Greek omogeneia has citizenship , but permanent living abroad, so they are considered as migrants when come to Greece.
they have Greek citizenship but not measured as permanent Hellenic population
lets not mix Citizenship, nationality, with permanent population,
for example at Kazakstan there were 21 villages with Greek origins at 1980's, some went at 1870's and had primary Ottoman identity
the ones who ask from Greek state took citizenship, but when came to Greece are considered as migrants Greeks from abroad, no matter have the citizenship.
Students are always excluded, as special category,
it is not difficult to understand the diffference among permanent living abroad, and permanent living in state.
BTW
Nativity has nothing to do with nationality
and has many types, there were 4-5 types before 80's
the permanent, non permanent living abroad, has to do with many state issues etc etc, as if the other countryis in EU treaties or not etc etc
for example
I Have all Hellenic pappers, citizenship nationality nativity A, taxation number, health insurance number etc etc.
and at my 30 years I move abroad to work, or dwell,
I must inform state, military, etc etc etc so to have different obligations, taxation, health etc etc,
I am temporary resident of abroad,
after a time I must decide if I want to declare permanent recidence abroad or not,
so to avoid problems with law, taxation,obligations etc,
I am not allowed to live abroad and take for example public aid from Greece (although it happened until 2008 crisis) as I am allowed not to be present for my military obligations etc etc
the ones you see as 1 year at the article, are also citizens that come 1 month per year, so not to lose priviledges etc etc,
for example came to Hellas, worked, but permanent living abroad, so they came to take their retirements, or taxes etc etc
