Population Projection - Geometric Projection

Population growth according to existing population at any given time.

Used for minor estimates deadline.

The curve fit can be also done by regression analysis

• First Census
  • Year of the First Census - Year of the First Census
    (FirstCensusYear)
  • Population at First Census - Population at First Census
    (FirstCensusPop)
• Second Census
  • Year of the Second Census - Year of the Second Census
    (SecondCensusYear)
  • Population at the Second Census - Population at the Second Census
    (SecondCensusPop)
• Start of the Project
  • Initial Year - Year the project started operating
    (StartYear)
  • Initial Population - Population at the beginning of the project
    (StartPop)
• Population Projection
  • Year of Projection - Year of End of Project
    (EndYear)
  • Final Population - Population at the end of the project
    (EndPop)
    EndPop = StartPop * Math.E ^ (kPop * (EndYear - StartYear))
  • Growth Rate - growth rate of the curve
    (kPop) kPop = (Math.Log(SecondCensusPop) - Math.Log(FirstCensusPop)) / (SecondCensusYear - FirstCensusYear)
