Editorial and data standard

1. No ranking of lives

A life expectancy of 54 years in one country and 84 in another is a difference in mortality conditions — healthcare access, income distribution, nutrition, sanitation, public safety. We describe it that way. We do not describe one country as better, more developed, more advanced, or less worthy than another, and we do not describe the people living in either as more or less capable.

The pages are written so that a reader in any of the 217 countries would recognise their own country described accurately rather than as a footnote to somewhere else.

2. Demographic groups

Where a country publishes an official breakdown of its population by caste, ethnicity, tribe or equivalent, we use that classification and name the body that defines it.

• A difference between groups is applied only when a published statistic supports it for that specific group in that specific country, and the source is named on the page.
• Notes describe structure — access to schooling, to work, to public services — never the character of the people in the group.
• No group is described as better or worse than another. The simulation shows how different starting conditions lead to different outcomes; it never suggests that a group caused its own circumstances.
• Where a country has no documented breakdown, the simulation uses national statistics and says so plainly, rather than inventing a classification.

3. Every number has a year

Each statistic is stored with the year it was observed and displayed with it. Missing data is shown as missing. We do not substitute an estimate for an absent figure, and we do not carry a number forward across years without saying so.

4. Death is described plainly, not dramatically

The simulation includes mortality, and a life can end early. We state a cause of death in the same tone we state anything else — a fact about a modelled life, not a spectacle. We do not use vivid language to make a death memorable, and we do not use child mortality or conflict deaths as entertainment.

Because this is a model, we say “the model produced this outcome” rather than “this will happen to you”.

5. Not advice

Nothing on this site is medical, financial, legal or immigration advice. The simulated health, happiness and agency scales are bookkeeping devices inside a model, not clinical or psychological measurements. Do not use a LifePath run to decide anything about your own life, your health, or where to live.

6. Advertising does not buy outcomes

Advertising is displayed on some pages. No advertiser has ever influenced a statistic, a calibration, an event, a consequence, or a conclusion, and no advertiser can request a change to one. Editorial decisions are made independently.

7. Privacy

The simulation runs entirely in your browser. Your choices, your seed, and the life they produce are never sent to a server, because there is no server receiving them. Cookies are used only to remember your consent choice and, if you accept, for analytics and advertising. See the privacy policy for detail.

8. Corrections

If we get a figure or a framing wrong, we want to fix it. Write to paomianll@126.com with the page and what you believe is correct. Corrections are applied to the published site, not hidden.
