India vs China: Is the population gap widening?
By ChartGlow · · 5 min read
India’s estimated population was about 42 million larger than China’s in 2024 in the World Bank’s latest retrieved World Development Indicators series. The two population series crossed in 2021 in this vintage. That answers the comparison in these data; it does not establish a definitive global rank, and population estimates can be revised.
Population estimates for seven countries, 1960–2024
India’s estimated lead in 2024
42.0 million
India: 1.4509 billion; China: 1.4090 billion. The difference is calculated from the two WDI values.
A changed ordering in the series
China was ahead by about 8.5 million in 2020. In 2021, India was ahead by about 1.8 million. The crossing is small at first, then the gap widens in the subsequent observations through 2024.
Seven countries, two endpoints
Values are in billions, rounded to three decimals. “Change” is the 2024 estimate minus the 1960 estimate, also in billions.
| Country | 1960 | 2024 | Change |
|---|---|---|---|
| India | 0.436 | 1.451 | +1.015 |
| China | 0.667 | 1.409 | +0.742 |
| United States | 0.181 | 0.340 | +0.159 |
| Indonesia | 0.088 | 0.283 | +0.195 |

Within this WDI vintage, yes: India’s lead grows from about 1.8 million in 2021 to 42.0 million in 2024. That is a description of the estimates, not a forecast of how large the difference will become.
Across all seven selected countries, India added an estimated 1.015 billion people between 1960 and 2024, versus 0.742 billion for China. The United States, Indonesia, Pakistan, Nigeria and Brazil also grew over the period. Pakistan and Nigeria each added roughly 0.2 billion, while their totals in 2024 remained far below India’s and China’s in this selection.
Population totals do not explain why populations changed. This chart does not measure fertility, migration, age structure, living standards or future growth; those need separate indicators and evidence. A difference between two estimates is not by itself a causal explanation.
Method, source and limits
Source: World Bank World Development Indicators API, indicator SP.POP.TOTL (Population, total), for India, China, the United States, Indonesia, Pakistan, Nigeria and Brazil, 1960–2024. The series was retrieved on 9 October 2026; the API response reported an update on 8 October 2026. See the World Bank’s indicator metadata for definition and sources.
The API values are persons. We divided each by 1,000,000,000 to express population in billions; no missing values were imputed. The indicator metadata describes total population as a midyear estimate using a de facto definition: residents regardless of legal status or citizenship. These are estimates, not a fresh headcount. WDI data can change when methods and underlying sources are revised, so the crossing year and gap belong to this retrieved vintage.
The selected data contain exactly seven countries, not every country or territory. They support comparing these seven series, but cannot independently prove a worldwide rank or the date when a global ranking changed. Sources listed by the World Bank include the UN Population Division / World Population Prospects and national statistical agencies. The data are made available under CC BY 4.0. Attribution: World Bank, World Development Indicators, SP.POP.TOTL; changes: selected seven countries, converted persons to billions, and animated presentation.

Questions readers ask
When did India’s population pass China’s in the World Bank series?
In the WDI vintage retrieved on 9 October 2026, India is below China in 2020 and above China in 2021. This is the crossing year in these two series; it is not a claim about a fully audited global rank.
How large was the India–China population gap in 2024?
The WDI estimates used here put India at about 1.451 billion and China at about 1.409 billion in 2024, a difference of roughly 42 million people.
Are these census counts?
No. They are World Bank WDI estimates of total population, generally midyear and using a de facto definition. Estimates and historical values can be revised as source data and methods change.
