📈 Population Projection Calculator – Logic

This tool helps project district or block population over time using a compound annual growth formula.

🔢 Inputs

  • Current population (base year)
  • Annual growth rate (%)
  • Number of years to project

📈 Formula Used

Population in Year N = Base Population × (1 + Growth Rate)^N

Where:

  • Growth rate is entered as a percentage (e.g., 1.85%)
  • N = number of years

🧠 Example

  • Current population = 520,000
  • Growth rate = 1.85%
  • Years = 5
Year 5 = 520,000 × (1.0185)^5 ≈ 572,215

Use this to project demands, resource needs, and future service planning.
