Math Problem Statement

2006= 184389 2.3% annual population change. Using The arithmetic geometric and exponential growth model project from 2024-2034

Solution

To project the population from 2024 to 2034 using different growth models—arithmetic, geometric, and exponential—based on a 2.3% annual population change rate, we'll calculate the expected population for each year under each model. The initial population in 2024 is assumed to be P0=184,389P_0 = 184,389.

1. Arithmetic Growth Model:

In an arithmetic growth model, the population increases by a constant absolute amount each year. This amount is derived from the initial population growth rate.

  • Annual Growth Amount: ΔP=P0×2.3100=184,389×0.023=4,240.947\Delta P = P_0 \times \frac{2.3}{100} = 184,389 \times 0.023 = 4,240.947

  • Population in Year nn (where nn is the number of years after 2024): P(n)=P0+n×ΔPP(n) = P_0 + n \times \Delta P

2. Geometric Growth Model:

In a geometric growth model, the population increases by a constant percentage each year.

  • Annual Growth Factor: r=1+2.3100=1.023r = 1 + \frac{2.3}{100} = 1.023

  • Population in Year nn: P(n)=P0×rnP(n) = P_0 \times r^n

3. Exponential Growth Model:

In an exponential growth model, the population grows continuously at a constant rate.

  • Exponential Growth Formula: P(t)=P0×ertP(t) = P_0 \times e^{rt} where r=2.3100=0.023r = \frac{2.3}{100} = 0.023 and tt is the number of years after 2024.

Let's compute the projected populations for each year from 2024 to 2034 under each model.

Projected Population Calculations:

I'll calculate the populations using the formulas above.Here are the projected populations for each year from 2024 to 2034 using the arithmetic, geometric, and exponential growth models:

Summary:

  • Arithmetic Growth: Adds a constant population increase of approximately 4,241 each year.
  • Geometric Growth: Multiplies the population by a constant factor of 1.023 each year.
  • Exponential Growth: Assumes continuous growth, leading to slightly higher population estimates compared to the geometric model by 2034.
