About

“World in Numbers” is a world map showing several dozen indicators for every country – from population and life expectancy to GDP, internet access and CO₂ emissions – and how they have changed year by year.

How to use the map

• Pick an indicator from the list in the panel next to the map. Under its name there is a short description: what exactly it measures and what to watch out for when comparing.
• The year axis below the map changes the year – drag the handle, click the axis or use the arrow keys. The ▶ button plays the changes year by year. The bars on the axis show how many countries have data for each year.
• Colours are value classes described in the legend. Class boundaries are set so that each class holds a similar number of countries in the starting year, and they stay fixed over time – so you can see the world moving along the scale. Hatched countries have no data.
• Clicking a country shows its value, its rank and a chart against the world average. The country page brings all indicators together.
• The page address remembers the indicator, year and country – copy it and share it.

Where the data comes from

• World Bank – the World Development Indicators database, fetched through its API. The Bank collects data from national statistics offices and UN agencies (WHO, UNESCO, ILO, ITU, FAO…), so for each indicator we also show who compiled it. Licence: CC BY 4.0.
• Our World in Data – additional series, including long historical records (GDP since 1820, CO₂ emissions since 1850), HDI and food. Licence: CC BY 4.0; each indicator names its original source. Exception: the FAO food data (calorie supply, meat supply) are licensed CC BY-NC-SA 3.0 IGO – non-commercial use only, with derived works under the same licence.
• Ember – the Yearly Electricity Data dataset: the share of each source in electricity generation (renewables, coal, nuclear, wind, solar), electricity generation per person and the carbon intensity of electricity, from 2000. Licence: CC BY 4.0. We calculate generation per person ourselves: Ember’s generation divided by World Bank population.
• Country borders: Natural Earth (public domain).

How the data stays up to date

We write the indicator descriptions ourselves; the numbers are fetched automatically by the import command – from the World Bank API, from Our World in Data files and from Ember’s data file. When a source publishes a new year or revises older values, the next import picks them up. Last fetched: 2 November 2026.

At first the map shows the latest year for which most countries have data – the most recent year is often still incomplete. Some indicators (such as inequality, poverty and literacy) come from surveys run every few years; when a year has no value, we show the latest one from a few earlier years and give its year in brackets.

Notes

• Values are rounded to five significant digits.
• Rankings go from the highest value down – which is not always “best” (think of mortality or emissions).
• Countries and territories follow the map; some small territories have no separate data in the sources.

Privacy

This site uses no cookies and stores nothing in your browser. We count visits with Matomo, which runs on our own server (stats.komba.pl), not with a third-party company.

One exception: if you choose the light or dark theme yourself (the switch in the header), your browser remembers that choice in its local storage (localStorage). It stays on your device and is never sent to us; in automatic mode nothing is stored.

• What is recorded: pages visited, the referring page, approximate location (country), language and the type of browser, operating system and device.
• IP addresses are shortened by their last two bytes (e.g. 192.168.x.x) before they are stored, so they do not identify a specific person.
• Why: only for visit statistics – to know which indicators and countries people look at. We do not share the data with anyone or combine it with other data.
• Legal basis: the controller’s legitimate interest (Art. 6(1)(f) GDPR).
• Contact form. When you write to us, we process your name or nickname, your e-mail address and the content of your message, as well as the name of the service and the page from which the message was sent. The message is delivered by e-mail to contact@ominuvo.com.
• Purpose and legal basis: replying to your message – on the basis of the consent you give in the form (Art. 6(1)(a) GDPR); protecting the form against spam and abuse – on the basis of the controller’s legitimate interest (Art. 6(1)(f) GDPR). Providing the data is voluntary, but without it we cannot reply.
• Spam protection: we store the sender’s IP address only as a hash (from which the address cannot be recovered) for the message limit, and delete it after an hour. The form does not use cookies.
• Recipients and retention: the data is stored by our hosting and e-mail provider, which processes it only on our behalf; we do not sell it or share it with others. We keep correspondence for as long as needed to reply, and then for no longer than 12 months, unless longer retention is required by law or for the defence of legal claims.
• Withdrawing consent: at any time, by writing to contact@ominuvo.com. Withdrawing consent does not affect the lawfulness of processing carried out before its withdrawal. You also have the right to data portability.
• Controller and contact: contact@ominuvo.com – write to ask about data that may concern you or to object. You also have the right to lodge a complaint with a data protection authority (in Poland: the President of the Personal Data Protection Office, UODO).
