Q. What is the density of the world population as a whole?
Answer: 16.1 per km²
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.
