Number of Decades given Future Population by Arithmetic Increase Method Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Decades = (Forecasted Population-Last Known Population)/Average Arithmetic Increase
n = (P_n-P_o)/X̄
This formula uses 4 Variables

Variables Used

Number of Decades - Number of Decades is the year gap of 10 years. Usually, 10 years is equal to 1 decade.
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

Forecasted Population: 350000 --> No Conversion Required
Last Known Population: 275000 --> No Conversion Required
Average Arithmetic Increase: 37500 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n = (P_n-P_o)/X̄ --> (350000-275000)/37500

Evaluating ... ...

n = 2

STEP 3: Convert Result to Output's Unit

2 --> No Conversion Required

FINAL ANSWER

2 <-- Number of Decades

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.
