n वर्षों के बाद जनसंख्या ज्ञात करने के लिए,
प्रारंभिक जनसंख्या को (1 + वार्षिक वृद्धि दर)n से गुणा कीजिए।
हल:
पहले वर्ष के बाद: 2000 × (1 + 0.002) = 2004
दूसरे वर्ष के बाद: 2004 × (1 + 0.004) = 2012.02
तीसरे वर्ष के बाद: 2012.02 × (1 - 0.004) = 2003.97
अतः 3 वर्ष बाद गाँव की जनसंख्या अनुमानित 2003.97 होगी।
