India and China are one of the world's most populated countries in the world. But China has a lesser population density compared to India. The population has been increasing in most of the developing countries due to improvement in healthcare and living conditions. But then there are other places in the world which are sparsely populated. In order to know which are the most populated and the least populated places, it is essential to understand the term, population density. Population density is a measure of population per unit area or unit volume. Put in simple terms, it is the total population of a country divided by the total land area of the country. The world is witnessing population explosion as the population has risen from 3 billion to 6.8 billion in the last 50 years. Yet there are still some areas on the surface of Earth that have low population density.
How does one determine population density?
Human beings account for a population of 6.8 billion while the total area of the Earth ( including land and water) is 510 million square kilometers. That makes the population density 6.8 billion /510 square kilometers = 13.3 sq km2. This figure is not completely true as a major portion of the Earth is also covered with water, deserts and mountains where human inhabitation is not quite possible. This changes the statistics of the population density.
How do least populated places affect the Earth's balance?
While most world statistics only talk about population explosion and densely populated places, there are still some places in the world which are examples of low population density. Places with least population can be cities, islands, countries or even a tribe. Least populated places may cause a threat of extinction which leads to reduced fertility. This in turn leads to complete extinction of the species.
