Rapid Growth -Larger bottom -Smaller top -Indicates population growth
Slow Growth -Fairly even -Lack of variation from top To bottom -Indicates slow population growth
No/Decreased Growth -Zero change between years (no growth) at beginning -Less population in following years (decreased growth) at mid years
Rapid Decrease -Larger top -Smaller bottom -Could be due to a plague or other disaster
