For those wondering the units

    Area is also in square km and population is in person.

    i.e. An area of 652230 really means 652230 million square km and a population of 78115 really means 78115 people.

    This may seem obvious but I guess it's better to state things clear: phrasing the question "A country is big if it has an area of bigger than 3 million square km or a population of more than 25 million" would make it clearer.
