Population Lookup
Choose a country from the dropdown and this tool fetches its latest population estimate live from the World Bank API (indicator SP.POP.TOTL) and shows the figure together with the reference year. No numbers are stored or precomputed — what you see is the most recent year the World Bank has published for that country.
This is a country-level tool only: it reports total national population estimates, not city-level or real-time figures. Population estimates are revised by the World Bank periodically, so the latest published year varies from country to country.
Country-level population only (latest World Bank estimate), not city-level. Figures are fetched live from the World Bank API — the exact figure shown depends on the most recent year the World Bank has published for the selected country.
How to use this tool
Pick one of the 40 listed countries from the dropdown menu.
The tool immediately requests the latest population data from the World Bank API for that country.
The population figure appears with its reference year and a clear "Source: World Bank" label.
What people use this tool for
Writers and students grab a citable national population figure with the exact reference year for articles and reports.
Analysts compare national populations across countries as a first input to addressable-market estimates.
Anyone curious about relative country sizes looks up two countries in sequence to compare their populations.
How it's calculated
The widget calls the World Bank's public API for indicator SP.POP.TOTL (population, total) for the selected country's ISO3 code, reads the response rows — which arrive latest-year first — and displays the first row with a non-null value, together with that row's year. If the API is unreachable or returns no usable data, the tool shows an honest error instead of a number.

Frequently asked questions
Is the population figure real-time?
No. It is the latest annual estimate published by the World Bank. The tool always shows the reference year so you know exactly which estimate you are seeing.
Can I look up a city's population?
No — this tool reports country-level totals only. The World Bank indicator it uses covers national population, not cities.
Why does the year differ between countries?
The World Bank publishes estimates on its own schedule, so the latest available year is not the same for every country. The tool always picks the newest non-null row for the country you selected.
What happens if the World Bank API is down?
You see an honest error message instead of a fabricated number. The tool never stores or invents population figures.
