Notes:
As of December 2024, the global population is approximately 8.2 billion people, with Earth’s total surface area around 510 million square kilometers (197 million square miles). Population Density Calculations:

• Total Surface Area (Land + Water):
  • Calculation: 8,200,000,000 ÷ 510,000,000 km² = 16.1 people per km² (41.7 per sq. mi.)
• Land Area Only:
  • Calculation: 8,200,000,000 ÷ 149,000,000 km² = 55.1 people per km² (142.7 per sq. mi.)
• Land Area Excluding Antarctica:
  • Calculation: 8,200,000,000 ÷ 148,939,000 km² = 55.1 people per km² (142.7 per sq. mi.)

These calculations provide a general overview of global population density. However, actual population distribution varies significantly across different regions due to factors like urbanization, geography, and socioeconomic conditions.

Notes:
Migration is driven by two types of factors, push and pull. Push factors, such as unemployment, poor living conditions, and socio-economic backwardness, discourage individuals from staying in their original place. Pull factors, on the other hand, make other locations more attractive. Better job opportunities, security, and indeed, a pleasant climate, are examples of pull factors – that might encourage people to migrate to a new location.
