Last Census Date for Geometric Increase Method Post Censal Solution

STEP 0: Pre-Calculation Summary
Formula Used
Last Census Date = Mid-Year Census Date-((log10(Population at Mid Year Census)-log10(Population at Last Census))/Proportionality Factor)
TL = TM-((log10(PM)-log10(PL))/KG)
This formula uses 1 Functions, 5 Variables
Functions Used
log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)
Variables Used
Last Census Date - The Last Census Date is the date at which the population is noted.
Mid-Year Census Date - Mid-Year Census Date is the date at which population is noted.
Population at Mid Year Census - Population at Mid Year Census is the population at the mid year census date.
Population at Last Census - Population at Last Census is the population at the date of last census.
Proportionality Factor - Proportionality Factor is defined as rate of change of population.
STEP 1: Convert Input(s) to Base Unit
Mid-Year Census Date: 29 --> No Conversion Required
Population at Mid Year Census: 40 --> No Conversion Required
Population at Last Census: 20.01 --> No Conversion Required
Proportionality Factor: 0.03 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
TL = TM-((log10(PM)-log10(PL))/KG) --> 29-((log10(40)-log10(20.01))/0.03)
Evaluating ... ...
TL = 18.9729032436083
STEP 3: Convert Result to Output's Unit
18.9729032436083 --> No Conversion Required
FINAL ANSWER
18.9729032436083 18.9729 <-- Last Census Date
(Calculation completed in 00.004 seconds)

Proportionality Factor for Geometric Increase Method Post Censal
Go Proportionality Factor = (log10(Population at Mid Year Census)-log10(Population at Last Census))/(Mid-Year Census Date- Last Census Date)
Mid Year Census Date for Geometric Increase Method Post Censal
Go Mid-Year Census Date = Last Census Date+((log10(Population at Mid Year Census)-log10(Population at Last Census))/Proportionality Factor)
Last Census Date for Geometric Increase Method Post Censal
Go Last Census Date = Mid-Year Census Date-((log10(Population at Mid Year Census)-log10(Population at Last Census))/Proportionality Factor)
Population at Last Census for Geometric Increase Method Post Censal
Go Population at Last Census = exp(log10(Population at Mid Year Census)-Proportionality Factor*(Mid-Year Census Date- Last Census Date))
Population at Mid Year for Geometric Increase Method Post Censal
Go Population at Mid Year Census = exp(log10(Population at Last Census)+Proportionality Factor*(Mid-Year Census Date- Last Census Date))
Population at Earlier Census given Proportionality Factor
Go Population at Earlier Census = exp(log10(Population at Last Census)-(Last Census Date-Earlier Census Date)*Proportionality Factor)

Last Census Date for Geometric Increase Method Post Censal Formula

Last Census Date = Mid-Year Census Date-((log10(Population at Mid Year Census)-log10(Population at Last Census))/Proportionality Factor)
TL = TM-((log10(PM)-log10(PL))/KG)

What is Geometric Increase Method?

The Geometric Increase Method is the population forecasting method in which the percentage increase in population from decade to decade is assumed to remain constant.It is also known as the logarithmic growth method or exponential growth method.
