Which best describes the age structure of a population with zero population growth? 4
the majority of people are of prereproductive ages in a broad-base pyramid age structure diagram.

the age-structure diagram would be narrow at the bottom and top with a broader middle.

the age structure would be broad at the top in postreproductive ages and narrow downward in an inverted pyramid.

the age-structure diagram would be column-shaped with all age classes approximately equal.
