In statistics, the population distribution of some variable within a population of some units is the set of values that the variable can take and how frequntly it takes that value.
Population need not have anything to do with people. It is simply a way of referring to the totality of the things that you are studying. For example, if you were studying the number of apples on each tree in an apple orchard, your population would be the apple trees in the orchard, the variable would be the number of apples per tree and the population distribution would be the number of trees that had 0 apples, the number that had 1 apple, 2 apples and so on. To make that information more manageable you may collapse the distribution to 0 apples, 1 to 25 apples, 26 to 50 apples and so on.
