Future Population at End of 2 Decades in Incremental Increase Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Forecasted Population = Last Known Population+2*Average Arithmetic Increase in Population+(2*(2+1)/2)*Average Incremental Increase in Population
P_n = P_o+2*x̄+(2*(2+1)/2)*ȳ
This formula uses 4 Variables

Variables Used

Forecasted Population - Forecasted Population is the population forested usually after n decade or after n years.
Last Known Population - Last Known Population is the population of any area of the previous year or decade.
Average Arithmetic Increase in Population - Average Arithmetic Increase in Population per decade.
Average Incremental Increase in Population - Average Incremental Increase in Population per decade. It can be positive(+ve) or negative(-ve).

STEP 1: Convert Input(s) to Base Unit

Last Known Population: 275000 --> No Conversion Required
Average Arithmetic Increase in Population: 25500 --> No Conversion Required
Average Incremental Increase in Population: 8000 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_n = P_o+2*x̄+(2*(2+1)/2)*ȳ --> 275000+2*25500+(2*(2+1)/2)*8000

Evaluating ... ...

P_n = 350000

STEP 3: Convert Result to Output's Unit

350000 --> No Conversion Required

FINAL ANSWER

350000 <-- Forecasted Population

What is Population Forecasting and Methods Involved?

Population forecasting is defined as the method of determining the expected population for a particular design period of a water supply system with the help of the study and analysis of future events and available records.
Methods are
1. Arithmetic Increase Method
2. Geometric Increase Method
3. Incremental Increase Method
4. Decrease Growth Rate Method
5. Logistic Curve Method
6. Demographic Method
7. Simple Graphical Method
8. Comparative Graphical Method
9. Master Plan Method
10. Ratio Method

What is Incremental Increase Method?

In this method, per decade growth rate is not assumed to be constant but is progressively increasing or decreasing, depending upon whether the average of the incremental increase in the past data is positive or negative.
It is also known as the Method of Varying Increment.
