Study Notes
- Projected populations for 2026 using different methods are:
- Arithmetical Increase: 36,615
- Geometrical Increase: 39,664
- Incremental Increase: 28,384
- Graphical Method: ~31,142
- The Incremental Increase Method is considered the most realistic due to a decline in growth rate and urban-to-metro migration.
- The projected population for the Development Plan is 28,500.
Population Projection Methods
-
The average increase in population per decade is called the arithmetical increase.
-
In the arithmetical method, if the average increase per decade is 4000 and N = 2, the population added to the base is 8000.
-
Geometrical increase assumes population increases by a constant percentage.
-
The exponential population growth method is also known as the geometrical method.
-
The incremental method showed the lowest population projection for 2026 in this case.
-
The average incremental increase in population was -1448.33 per decade.
-
Incremental increase refers to the rate of increase in the growth rate.
-
The incremental method is best suited when population growth is declining.
-
The graphical method is best used when accurate statistical data is not available.
-
The formula ( P_n = P_0 + N \cdot I_a + \frac{N(N+1)}{2} \cdot I_i ) is used in the incremental method.
-
The value of N used in all methods in the example is 1.5.
-
"Souls" represent individual persons in the context of population data.
-
The incremental method was preferred for final planning because it reflects a declining trend.
-
If the population was 27500 in 2011 and 31142 in 2021, the average increase per decade is 3648.75.
-
The projected population by the graphical method in this case is 31142.
-
The main limitation of the geometrical increase method is that it is not suitable when growth is declining.
-
The arithmetical method always projects population linearly.
-
The value of ( P_s ) by the Arithmetical Increase Method was 36615.
-
The expression (1 + Ra)^N is used in the geometrical method.
-
The final population projection adopted for the Development Plan is 28,500.
