SOUTHERN ASIA:

A Demographic Overview of the Most Populated Subregion in Asia

Southern Asia is home to nearly 2 billion people, making it the most populous subregion in Asia and the world. As of November 7, 2022, the current population of Southern Asia stands at 1,992,152,966, based on the latest United Nations estimates. In this article, we’ll take a closer look at the demographics of this region, including population density, urbanization, and median age.

Population Size and Density in Southern Asia

With a population of almost 2 billion people, Southern Asia accounts for approximately 24.89% of the world’s total population. This subregion is also the most densely populated, with a population density of 303 per square kilometer (785 people per square mile). This high population density is due to the fact that Southern Asia is comprised of several countries with large populations, such as India, Pakistan, and Bangladesh.

Land Area and Ranking in Asia

The total land area of Southern Asia is 6,400,127 square kilometers (2,471,102 square miles), making it the seventh-largest subregion in Asia. However, despite not being the largest in terms of land area, Southern Asia ranks number one in Asia when subregions are ranked by population.

Urbanization in Southern Asia

As of 2019, 36.6% of Southern Asia’s population was urban, which equates to around 709,387,963 people. This figure is expected to continue to rise over the coming years as more and more people migrate from rural areas to cities in search of better opportunities and a higher quality of life.

Median Age in Southern Asia

The median age in Southern Asia is relatively young, standing at 27.6 years. This is partly due to high birth rates in the region, which are offsetting declining mortality rates. The youthfulness of Southern Asia’s population presents both opportunities and challenges for the region. On one hand, a young and growing population can drive economic growth and development. On the other hand, it can also place pressure on infrastructure and resources, particularly in urban areas.

Understanding the Demographics of Southern Asia: Key Terms Explained

Year

The term “year” refers to the period from July 1 of the year indicated. This period is used as a reference point for all demographic data related to Asia.

Population

The population refers to the overall total population (both sexes and all ages) in the region as of July 1 of the year indicated. This data is estimated by the United Nations, Department of Economic and Social Affairs, Population Division using the World Population Prospects: The 2019 Revision. For forecasted years, the U.N. medium-fertility variant is used.

Yearly (Annual) % Change

The yearly % change is the percentage change in total population over the last year (from July 1, 2018, to June 30, 2019) for the year 2019. For all other years, the latest year’s annual percentage change is equivalent to assuming homogeneous change in the preceding five-year period, calculated through reverse compounding.

Yearly (Annual) Change

The yearly change refers to the absolute change in total population (increase or decrease in a number of people) over the last year (from July 1, 2018, to June 30, 2019) for the year 2019. For all other years, it is the average annual numerical change over the preceding five-year period.

Migrants (net)

Migrants (net) refer to the average annual number of immigrants minus the number of emigrants over the preceding five-year period (running from July 1 to June 30 of the initial and final years), or subsequent five-year period (for 2016 data). A negative number means that there are more emigrants than immigrants.

Median Age

The median age is the age that divides the population into two numerically equal groups: half of the people are older than the median age indicated and half are younger. This parameter provides an indication of age distribution.

Fertility Rate

The fertility rate (Total Fertility Rate, or TFR) is expressed as children per woman. It is calculated as the average number of children an average woman will have during her reproductive period (15 to 49 years old) based on the current fertility rates of every age group in the countries within Asia, assuming she is not subject to mortality.

Density (P/Km²)

Density (P/Km²) refers to the population density or the population per square kilometer (Km²) in a given region.

Urban Pop %

The urban pop % is the percentage of the urban population in relation to the total population in a given region.

Urban Population

The urban population refers to the population living in areas classified as urban according to the criteria used by each country.

Southern Asia’s Share of World Pop.

Total population as a percentage of total World Population as of July 1 of the year indicated.

World Population

The world population refers to the total population of the world as of July 1 of the year indicated.

Global Rank

The global rank is the position held by Asia in the list of all regions worldwide ranked by population (from the highest population to the lowest population) as of July 1 of the year indicated.

By understanding these key terms, one can gain a deeper understanding of the demographics of Asia and how they relate to the rest of the world.
