A countable set has elements (or members) that can be listed, like the numbers 1, 2, 3, and so on. You must be able to associate each element with a natural number. The interval of all the real numbers between 0 and 1, is not countable. But the interval of all rational numbers between 0 and 1 is countable. We could list the first element as 0, the second element as 1, the third element as 1/2, the fourth as 1/4, the fifth as 3/4, the sixth as 1/3, the seventh as 2/3, and so on. This set is also infinite because there is no finite bound on the number of elements. The term "population" has many meanings. A "countable infinite population" probably refers to a statistical population. This is a particular kind of set considered by statistics.

A countable infinite population refers to a group of individuals for which there exists a one-to-one correspondence with the natural numbers (1, 2, 3, ...). This means that the population size can be enumerated infinitely, with each individual uniquely identified by a distinct natural number index.

What do you mean by countably infinite and infinite?
Countably infinite means you can set up a one-to-one correspondence between the set in question and the set of natural numbers. It can be shown that no such relationship can be established between the set of real numbers and the natural numbers, thus the set of real numbers is not "countable", but it is infinite.

What do rational and irrational numbers have in common?
Rational and irrational numbers are part of the set of real numbers. There are an infinite number of rational numbers and an infinite number of irrational numbers. But rational numbers are countable infinite, while irrational are uncountable. You can search for these terms for more information. Basically, countable means that you could arrange them in such a way as to count each and every one (though you'd never count them all since there is an infinite number of them). I guess another similarity is: the set of rational numbers is closed for addition and subtraction; the set of irrational numbers is closed for addition and subtraction.
