1. What is Proportionality Factor?

The Proportionality Factor (KG) is defined as the rate of change of population in the Geometric Increase Method. It represents the constant factor by which the population changes geometrically over time.

2. How Does the Calculator Work?

The calculator uses the Proportionality Factor formula:

\[ KG = \frac{\log_{10}(PM) - \log_{10}(PL)}{TM - TL} \]

Where:

\( KG \) — Proportionality Factor
\( PM \) — Population at Mid Year Census
\( PL \) — Population at Last Census
\( TM \) — Mid-Year Census Date
\( TL \) — Last Census Date

Explanation: The formula calculates the rate of population change using logarithmic transformation to handle geometric growth patterns.

3. Importance of Proportionality Factor

Details: The Proportionality Factor is crucial for population forecasting and demographic analysis. It helps in predicting future population trends and planning for resource allocation based on geometric population growth patterns.

4. Using the Calculator

Tips: Enter population values in persons and census dates in years. All values must be valid (populations > 0, TM > TL).

5. Frequently Asked Questions (FAQ)

Q1: What is the Geometric Increase Method?
A: The Geometric Increase Method assumes that population growth follows a geometric progression, where the population increases by a constant ratio over equal time intervals.

Q2: When should this method be used?
A: This method is suitable for areas experiencing consistent geometric population growth, typically in developing regions or rapidly growing urban areas.

Q3: What are the limitations of this method?
A: The method assumes constant growth rate, which may not hold true over long periods due to changing economic, social, or environmental factors.

Q4: How accurate are the predictions?
A: Accuracy depends on the consistency of past growth patterns and the assumption that future growth will follow the same geometric progression.

Q5: Can this method be used for short-term forecasts?
A: Yes, this method is generally more reliable for short to medium-term population forecasts rather than long-term predictions.
