Future Population at End of 3 Decades by Arithmetic Increase Method Solution

STEP 0: Pre-Calculation Summary
Formula Used
Forecasted Population = Last Known Population+3*Average Arithmetic Increase
Pn = Po+3*
This formula uses 3 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 - Average Arithmetic Increase in population is the arithmetic sum of the population increase of the previous decade.
STEP 1: Convert Input(s) to Base Unit
Last Known Population: 275000 --> No Conversion Required
Average Arithmetic Increase: 37500 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Pn = Po+3*X̄ --> 275000+3*37500
Evaluating ... ...
Pn = 387500
STEP 3: Convert Result to Output's Unit
387500 --> No Conversion Required
FINAL ANSWER
387500 <-- Forecasted Population
(Calculation completed in 00.004 seconds)

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

Assumptions in Arithmetic Increase Method

1. The population increases at a constant rate i.e., the rate of change of population with time (dp/dt) is constant.
2. It is applicable to old and large cities.
3. This method yields lower results for rapidly growing cities.
