1) ex.>humans
- long life, sex. maturity late, fewer offspring
2) ex> mice, mature sexually  quickly, high mortality  through out life, many offspring
3) ex> sea turtles
 high youth mortality, few adults , long lives
population change = [ (births + immigration) - (deaths + emigration) ] x 100 =   Y  %
