Population at Earlier Census Solution

STEP 0: Pre-Calculation Summary

Formula Used

Population at Earlier Census = Population at Last Census-Constant Factor*(Last Census Date-Earlier Census Date)
P_E = P_L-K_A*(T_L-T_E)
This formula uses 5 Variables

Variables Used

Population at Earlier Census - Population at Earlier Census is the population at the earlier census date.
Population at Last Census - Population at Last Census is the population at the date of last census.
Constant Factor - Constant Factor is defined as rate of change of population.
Last Census Date - The Last Census Date is the date at which the population is noted.
Earlier Census Date - Earlier Census Date is the date at which the population is noted.

STEP 1: Convert Input(s) to Base Unit

Population at Last Census: 20.01 --> No Conversion Required
Constant Factor: 2 --> No Conversion Required
Last Census Date: 19 --> No Conversion Required
Earlier Census Date: 20 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_E = P_L-K_A*(T_L-T_E) --> 20.01-2*(19-20)

Evaluating ... ...

P_E = 22.01

STEP 3: Convert Result to Output's Unit

22.01 --> No Conversion Required

FINAL ANSWER

22.01 <-- Population at Earlier Census

Earlier Census Date given Proportionality Factor

Go Earlier Census Date = Last Census Date-((log(Population at Last Census,e)-log(Population at Earlier Census,e))/Proportionality Factor)

Last Census Date given Proportionality Factor

Go Last Census Date = Earlier Census Date+((log(Population at Last Census,e)-log(Population at Earlier Census,e))/Proportionality Factor)

Proportionality Factor given Population at Last Census

Go Proportionality Factor = (log10(Population at Last Census)-log10(Population at Earlier Census))/(Last Census Date-Earlier Census Date)

Population at Last Census given Proportionality Factor

Go Population at Last Census = exp((Last Census Date-Earlier Census Date)*Proportionality Factor+log10(Population at Earlier Census))

Constant Factor given Population at Last Census

Go Constant Factor = (Population at Last Census-Population at Earlier Census)/(Last Census Date-Earlier Census Date)

Earlier Census Date given Constant Factor

Go Earlier Census Date = Last Census Date-((Population at Last Census-Population at Earlier Census)/Constant Factor)

Last Census Date given Constant Factor

Go Last Census Date = Earlier Census Date+((Population at Last Census-Population at Earlier Census)/Constant Factor)

Population at Earlier Census

Go Population at Earlier Census = Population at Last Census-Constant Factor*(Last Census Date-Earlier Census Date)

Population at Last Census

Go Population at Last Census = Population at Earlier Census+Constant Factor*(Last Census Date-Earlier Census Date)

Population at Earlier Census Formula

Population at Earlier Census = Population at Last Census-Constant Factor*(Last Census Date-Earlier Census Date)
P_E = P_L-K_A*(T_L-T_E)

What is Population?

A Population is a distinct group of individuals, whether that group comprises a nation or a group of people with a common characteristic.
