    Laura,

     

    Population pyramids allow for a better understanding of demography, which is "the study of statistics such as births, deaths, income, or the incidence of disease, which illustrate the changing structure of human populations". This is usefull because you can get a snapshot of what a given population is up to, aka: how many of a particular age, when were they born, aging trends, mortality, etc... The information they give is often sourced for urban planning and development viability studies.

    The typical layout is read from the bottom up (youngest on bottom, oldest on top). Male on the left, female on the right. As you read up from the bottom simple mortality forms a curve to the point where there are no more member s of that given age set. India is an example of this type of typical demography (see below).

    However, there are exceptions to this optimal pattern. Russia is currently experiencing a population decrease (see below).

    The term "aging in place" (found in the site planning and design handbook) makes use of demographic studies to make conclusions on what type of developments and features will be most appropriate as the U.S. population ages.

    On a broader topic, global market and security analysts also use demographics to plot likely outcomes in the economic and security sectors (search youtube for "Peter Zeihan" and watch one of his shorter presentations - quite an insiteful / entertaining way to get a feel for this subject).

    Hop that helped.

    Good luck.

    Population Pyramid

    To own the concept of the population pyramid, which is relevant to the ARE, see this Hans Rosling video. If you want to see more content by this recently-deceased Swedish physician, public health champion, and “person who thinks graphically like an architect,” go here.  I can also highly recommend his books. For those of you who are pessimists, a warning that you will come away with a feeling that humanity is doing well. For those who like data, demographics, or the illustration of data in novel graphic formats, you’ll love his stuff.—Michael Ermann, The Amber Book
