a graphic representation of the age structure of a population at a given time
a graph that shows the population breakdown by age of a given country
a graph which shows the age and sex structures of a population
a series of stacked bar graphs with each bar representing a given age cohort and the height of the bars representing the fraction of the population made up of members of that cohort
a special type of graph that shows the age-sex composition of a
The population is divided into age groups known as cohorts on the vertical axis (e.g. 25-29) while the x-axis is divides into male and female either side of the y-axis. The number in each age group is given as a percentage of the total population and is shown by horizontal bars with males to the left and females to the right.
A vertical bar graph showing the distribution of people in a population by age and sex. Males are conventionally plotted on the left side of the graph, females on the right.
diagram usually a bar chart depicting the distribution of a given population by age and sex. By convention, the younger ages are at the bottom, with males on the left and females on the right
A bar chart, arranged vertically, that shows the distribution of a population by age and sex. By convention, the younger ages are at the bottom, with males on the left and females on the right.
A graphic representation of the distribution of a population by sex and age.
A population pyramid is a graphical illustration that shows the distribution of various age groups in a population (typically that of a country or region of the world), which normally forms the shape of a pyramid. It typically consists of two back-to-back bar graphs, with population plotted on the X-axis and age on the Y-axis, one showing the number of males and one showing females in a particular population in five-year age groups (also called cohorts). Males are conventionally shown on the left and females on the right, and they may be measured by raw number or as a percentage of the total population.
