Population Pyramids

Population and Migration Chapter 2 - Population Pyramids

Demography is concerned with population growth and the characteristics of the population
Important Characteristics age and gender
Sex Ratio the number of males compared to females in a population
Population Pyramid analyzing it is one of the easiest ways to identify a population's sex ratio
Population Pyramids chart populations on a graph
Population Pyramid Graphs breaks down the population based on both gender and age and can be analyzed in terms of the DMT
Population Pyramids good ways to analyze population projections
Population Projections use demographic data to determine future population
Population Projections only work if the governmental structure and cultural customs remain the same
Population Pyramids of Less Developed Countries have a wide base because the majority of the population is under the age of 15.
Dependancy Ratio says that those ages 0-14 and over 65 depend on the workforce for support
Demographic Momentum is a continued population increase as a result of a large segment of the population being young
Demographic Momentum countries in stage two have it
Negative Growth when the country begins to lose population (stage 4)
Population Pyramids do not only have to be used on a national scale, but can be used to describe cities or even neighborhoods
Information Gathered allows governments to develop policies and allocate resources to meet the current and future needs of the population
