Is this real-time data?

No · it is a simulation built from real statistics. Each flash is generated mathematically from a country's population and its crude birth and death rates, not from any live record of actual events. The pattern and pace are realistic; the individual flashes are not real people.

Where do the numbers come from?

The crude birth and death rates come from the UN World Population Prospects, combined with each country's population. The page links to the source.

Why do some countries barely flash?

A country lights up in proportion to its population times its birth or death rate. A country of a few million simply has far fewer births and deaths than one of a billion, so it flashes much less often · just like reality.

What does "net change" mean?

It is births minus deaths since you opened the page · the natural population change before migration. Worldwide it stays strongly positive, because births outnumber deaths.

Does it work offline?

Yes. PlayMemorize is a Progressive Web App, so Human Map keeps running without a connection once the page has loaded.

About Human Map

Human Map is a living picture of humanity's heartbeat. Every dot on the map is a country, placed at its real position on the globe, and it flashes green the instant a baby is born and red the instant someone dies. Nothing here is a live news feed · every pulse is generated from the maths, using each country's real population and its crude birth and death rates.

How the maths works. A country's crude birth rate is the number of births per 1,000 people per year; the crude death rate is the same for deaths. Multiply the rate by the population and you get births (or deaths) per year; divide that down to the millisecond and you know, on average, how often that country should light up. Big, fast-growing countries like India and Nigeria flash constantly; small or ageing ones flash rarely · which is exactly how the real world behaves.

Filter and explore. Switch between births only, deaths only, or both, and watch the running totals climb. Hover or focus any country to see how many births and deaths it has notched up since you opened the page, and the small leaderboard shows where the most is happening.

Why it is striking. Seen one at a time, a birth or a death is an abstraction. Seen as a flickering map, the scale and rhythm of human life becomes something you can feel · roughly four births and two deaths every second, worldwide, the clock never stopping.

Rates are drawn from the UN World Population Prospects. Part of the PlayMemorize family · runs entirely in your browser and works offline as a Progressive Web App.
