Today in
Human Geo we had a substitute. Our substitute today was Mrs. Amato. We watched
a video on Population Pyramids. One thing I learned is that Russia and Nigeria
has the same population. But not for long because one population is rapidly
growing while the other is slowly declining. Another thing I learned about is
that Population statistics is important information to Social scientists has to
work with. Complex data is easier to comprehend by visualization. A way they
make the information easier to read is a population pyramid. The pyramid is separated
by gender and is divided into every five year intervals. The pyramid starts at
0-4 and ends at 100 and up. The pyramid is divided into pre- reproductive years
which is the ages 0-14, reproductive ages 15-44, and post reproductive ages 45-
100+. Another thing we did in your class today is take a quiz that is on your
blog. The answers are below.
