Explanation: In the arithmetic increase method, Dp/dt = K where Dp/dt = rate of change of population and K is a constant. So, the increase in the population from decade to decade is assumed constant.

Arithmetical Increase Method
In the arithmetical increase method of population forecasting, the increase in population from decade to decade is assumed to be constant. This method assumes that the population grows at a fixed rate over time. This rate is usually determined based on historical data or trends.
Explanation:
The arithmetical increase method assumes that the population increases by a fixed number of individuals in each decade. This means that the rate of growth remains constant over time. For example, if the population increases by 1000 individuals every decade, this increase is assumed to be consistent from one decade to the next.
This method is based on the assumption that the factors influencing population growth remain constant over time. It does not take into account any changes in birth rates, death rates, immigration, or other factors that may affect population growth. Therefore, it is a simple and rudimentary method of population forecasting that does not consider the complexity of demographic changes.
Advantages:
- The arithmetical increase method is simple and easy to use, requiring only basic mathematical calculations.
- It provides a rough estimate of population growth based on a constant rate of increase.
Limitations:
- This method does not consider the impact of various demographic factors on population growth, such as changes in birth rates, death rates, or migration.
- It assumes a constant rate of growth, which may not hold true in reality. Population growth rates can fluctuate over time due to various social, economic, and environmental factors.
- The arithmetical increase method does not account for population dynamics or changes in population structure.
In conclusion, the arithmetical increase method assumes a constant rate of increase in population from one decade to the next. While this method is simple and easy to use, it does not consider the complexities of demographic changes and may provide inaccurate population forecasts.
