On one hand the universe contains "all the entities one wishes to consider in a given situation" on the other the population is "a set of similar items or events which is of interest for some question or experiment".

A co-worker said when she learned statistics they used the word universe; when I did we said population. Neither of us had heard of the other word. What if any is the difference?

I just took stats last year. Population is, as you described, a complete set of elements (persons or objects) that possess some common characteristic defined by the sampling criteria established by the researcher.

In statistics, Universe is a synonym of Population.

Source: population. (n.d.) Collins English Dictionary – Complete and Unabridged, 12th Edition 2014. (1991, 1994, 1998, 2000, 2003, 2006, 2007, 2009, 2011, 2014). Retrieved October 20 2017 from https://www.thefreedictionary.com/population

Confirming the use of Universe and Population, as synonyms in modern data science:

The collection of all elements possessing common characteristics that comprise universe is known as the population. A subgroup of the members of population chosen for participation in the study is called sample. The population consists of each and every element of the entire group.

Universe is the set all experimental units, from which a sample is to be drawn. Population is the set of all values of the variables to be studied from those experimental units. Thus, a U-sample contains experimental units, whereas a P-sample contains data.

The collection of all elements possessing common characteristic that comprise (Univers) is known as the population.

And the subgroup of the member of population chosen for participating in the studybis called (Sample).

Universe, population and sample must be understood together. Universe and population can refer to same thing and can be considered as synonym if only the population you use while choosing your samples includes all the members of universe. If you have data for all the members of universe then your population is universe and you are actually sampling from the universe. However, if you have data for only some members of universe then your population is those members of universe only and you are sampling from those members of universe whose data you have access. For instance, let's say you are doing a survey research on 10 million workers in country X. Your universe is all the workers. If you have access to social security number of all the workers where you can draw your sample of 10 thousand workers, then your universe and population are the same. If you have access to social security numbers of only 1 million workers then your universe is 10 million workers, your population is 1 million workers, and your sample is 10 thousand workers.

Is a complete set of persons or objects that posses some common characteristics that are of interest to the researcher?

What is the entire set of individuals or objects having some common characteristic selected for a research study?

Is a complete set of people with a specialized set of characteristics?

What group of population that is composed of the entire group of people or objects to which the researcher wishes to generalize the findings of the study?
