The type of population pyramid that shows a low percentage of young people is the constrictive pyramid.

Explanation:

The population pyramid is a pyramid-shaped diagram illustrating the age structure and gender distribution of the population. The population pyramid is a pairwise horizontal bar graph showing population on the x-axis and age on the y-axis. The bars on the left represent the number of men and the bars on the right the number of women, for example, in the age group of five. The gender distribution can be expressed as a numeric or as a percentage. Population pyramids help to understand the structure of the population by pictorial representation of several features of the population simultaneously.  

A constrictive pyramid means a high proportion of the aging population, few children and a shrinking population. This shows that the birth rate is decreasing.
