India’s Population: Becoming Number One

By 2024, India will slip past China to become the most populous country and must rapidly prepare for a fast-changing economy.

India will likely hold that rank throughout the 21st century. Its population is 1.34 billion, nearly a fourfold increase since independence 70 years ago. China’s population, at 1.41 billion, roughly doubled over the same period. The pace of India’s population growth, now at 15 million per year, is the world’s largest. The two nations alone have more than a billion people, and their population gap is projected to widen to 500 million by 2100. By comparison, the third and fourth most populous countries in 2100, Nigeria and the United States, are projected to have populations of nearly 800 million and 450 million, respectively.

The long-term growth of India’s population, largely a function of fertility rates, is less certain. UN population projections indicate a range of possible scenarios. For example, if India’s current fertility of 2.3 births per woman remains constant, its population would grow to 1.8 billion by 2050 and 2.5 billion by 2100. Even under the instant-replacement fertility variant, with the country’s fertility assumed to fall immediately to 2.1 births per woman, India’s population would reach 1.9 billion by the century’s close.

Easing One-Child Policy May Be Too Late

In an attempt to mitigate a near-certain demographic future of rapid aging, shrinking labor force and critical gender imbalance, the Chinese government has adjusted its one-child policy. The decision demonstrates that, irrespective of a nation’s politico-economic system, governments cannot avoid demography’s juggernaut consequences. This mid-course correction in population policy will have marginal effect as China is aging at a much faster pace than occurred in other countries. This, along with a shrinking workforce and critical gender imbalance, will increasingly tax the government.

The new policy, set at the provincial level, will permit couples to have two children if either the husband or wife is an only child. Under the previous policy, two children were allowed for ethnic minorities, rural families whose firstborn is a daughter, and couples with both spouses as only children.

China instituted its one-child policy in the late 1970s because it feared that its rapidly growing population placed an untenable burden on economic growth and improving standards of living. At the start of the 1970s, China’s fertility rate was above five children per couple and its population was growing at more than 2 percent per year, adding more than 20 million Chinese annually. If the demographic growth of the 1970s had persisted, China would perhaps have added 400 million people more to its current population of 1.39 billion.
