A sociologist studying population features might study:
the language of the people
where people live
how many people move in or out of an area
changes brought about by new inventions
how many people die and are born in an area
Which ones?
If a sociologist were studying population features, they would focus on numbers of people in the area, not how or where they live. So he/she would study: How many people move in or out of an area and How many people die and are born in an area.
