Answer:
Yes, it is effectively infinite
Step-by-step explanation:
An effectively infinite population refers to population from which it is possible to obtain a computable sub-population from it, and it is also effectively possible to construct another new sub-population from that same population that will not have elements already contained in the first sub-population.
The attributes of this kind of population is called effective infinity.
Database of recent graduates of any university possess this kind of attributes since it is possible to obtain another over 30,000 recent graduates from the database that will not have elements of the first 30,000.
