Reincarnation SimulatorIf life is a movie, why not watch a few more?

Earth's countless lives · Random birth · One life only

The next new life
could beyou.

Every second on Earth, countless lives begin: babies, puppies, chicks, fish fry, mosquitoes, bees. You can't choose what you'll be or where you'll be born. Using population and health statistics from all 199 countries and regions of the world, plus the real lifespans and fates of over a hundred kinds of animals and insects, the Reincarnation Simulator drops you somewhere at random. From the moment you're born, you grow one tree ring a year.

What's new

Recent updates to the Rebirth Simulator.

  1. China from 3000 BCE: the Three Sovereigns and Five Emperors and the Xia are marked as legend; after that every day is dated by the dynasty's era name, the sexagenary cycle and the lunar calendar, with 283 real events, and those whose exact date can't be verified are marked as approximate. Your status at birth follows each dynasty's real proportions, mostly smallholders and tenant farmers; you may be drafted for corvée on the Great Wall or the canals or for the army, or work your way up the imperial exams, but you never become a famous historical figure. Chinese lives now run from 3000 BCE to today.

  2. China 1912–2026: from the Republic, the war against Japan and the civil war to the People's Republic, with everyday background for every year and 362 real dated events. Lives follow the era: city or village, household registration, class labels, being sent down to the countryside, the restored university exam, the one-child policy, layoffs and migrant work. Manchukuo, occupied areas, the foreign concessions and the special economic zones each differ.

  3. The site now opens in your device's language automatically, Traditional Chinese, Simplified Chinese, English, Japanese or Korean, including links other people share with you. Once you switch with the language menu at the top right, your choice is remembered.

Earlier updates
  1. Life Theater, rebuilt: every kind of thing that can happen in a life now has its own scene, 179 in all, from first words, a new little brother or sister, matchmaking, weddings, school and losing a job to war, air raids, earthquakes, tsunamis, downpours, typhoons, volcanoes and famine. Animals, insects, plants and microbes have their own scenes too. Each life has a fixed cast: your parents, siblings, partner and children keep the same look throughout and grow old; the setting, weather and staging vary every time.

  2. New Life Theater: a TV in the middle of the game screen acts out your life with characters, and the life log now sits below it. There are 10 scenes so far, birth, learning, love, wedding, new life, work, illness, moving, historic events and farewell, each played differently for humans and animals. The site also has a tagline: “If life is a movie, why not watch a few more?”

  3. Taiwan gains 56 events from everyday life, such as the Japanese-language 'national language families', the fertilizer-for-rice barter, 'living rooms as factories', the Patriotic Lottery, the Da Jia Le numbers craze, alternate Saturdays off, the EasyCard and the last joint university entrance exam; the 19 whose exact date can't be verified are marked as approximate.

  4. Japan from its first written record in 57 CE: every day is dated in the era name and old lunisolar calendar of the time, with 384 real events; where the exact date can't be verified, it is marked as approximate. Your status at birth follows each era's real proportions, so most people are farmers; in the Warring States period you may be levied as an ashigaru foot soldier and march in real campaigns such as Odawara in 1590, the invasion of Korea in 1592 and Sekigahara in 1600.

  5. Lives born in the future now follow each country's projections from the UN World Population Prospects 2024 for lifespan and health, using the medical care of each year they live through; technology, climate change (IPCC Sixth Assessment Report) and each country's legal retirement age are added. Everything about the future is labelled as a projection.

  6. Japan 1926–2026: every year's environment, daily life, work, politics and building, plus 375 real dated events such as the end of the war, the Tokyo Olympics, the Great Hanshin-Awaji and Great East Japan earthquakes, and the Heisei and Reiwa era changes. Regions differ, and Okinawa follows its own history under US administration until 1972.

  7. Taiwan 1926–2026: every year's environment, daily life, business, politics and building, with 318 dated events stored in the database; every day has its lunar date, solar term, festivals and school term. Anyone alive in the year of the 921 earthquake, the 228 Incident or the end of martial law will live through it.

  8. The pause dialog now continues by itself after five quiet seconds.

  9. Bacteria, viruses and parasites: 100 common microbes can now be reborn, with lives counted in minutes or hours.

  10. The timeline now reaches back three thousand years: you can be born from 1000 BCE on, with each era's own states, societies and events.

  11. Human lives now include sexual orientation and gender identity, each country's laws by year (same-sex marriage, divorce, abortion, military service and more), religion, and a family background drawn from each country's real income distribution.

  12. Richer lives for pets, farm animals, wild animals, insects and plants, each with its own real circumstances and choices.

  13. All 199 countries and territories, each with its own school system; birthplaces are the real administrative divisions of the time.

  14. Rebirth odds: work out how likely your next life is to be the country or creature you want.

  15. 100 relaxing background tracks you can skip through; the homepage shows live counts of the world's births and deaths today.

  16. 100 plants, a public memorial, and English, Japanese, Korean and Simplified Chinese versions.

Field 3

Country of birth

Every life starts at age 0. Wild animals are born in their natural habitat.

This field is stored only in your browser.

Field 4

Length of life

Based on the average human lifespan. Animal lives are shorter and are scaled to their real lifespans.

Includes illness, poverty, violence, and death. Recommended for ages 15 and up.

How a Life Works

Four stats

Health Affects your risk of death and ability to work. Exercise and medical care raise it; age lowers it.

Happiness Life satisfaction. Shaped by income, relationships, health, and debt.

Knowledge Affects schooling, jobs, and starting pay. Family background and your country's education level matter a lot.

Relationships Your bonds with family and friends. Marriage, children, bullying, and loneliness in old age all change it.

Higher stats make good things more likely, but nothing is guaranteed. Luck and circumstance matter just as much.

Born in the same second

Four other people born in the same second as you live their lives alongside yours, using the same statistics. You can check on them any time.

Life decisions

School, work, love, moving, treatment: at key moments, you decide. Or press "Leave It to Fate," pick a priority, and let it choose for you.

Pause points

At ages 5, 15, 30, 50, and 70, time stops and asks you a question. You can write a line or not. You at that age will answer back.

Memorial

When a life ends, you can leave an epitaph, place it in the Memorial, and light a candle.

Field Guide

Every creature and breed you could be reborn as. Typical lifespan in parentheses.

Rebirth odds

What are the odds that your next life is exactly the one you want?

Memorial

Every life lived here stays here. Anyone can light a candle or leave a few words for them.

Data & Methods

Birth years can go as far back as 1000 BCE. Before 1800 the game uses a separate set of historical data: regional populations (McEvedy & Jones, HYDE, Maddison), life expectancy and infant mortality, the states of the time, social status and occupations (slaves, serfs, castes, samurai, the imperial examinations), literacy and education, marriage customs, the laws and religious attitudes toward same-sex relationships, when infectious diseases reached each region (for example, smallpox reached the Americas only after 1518), and nearly five hundred ancient wars, famines, plagues and persecutions. Animals and plants likewise appear only where the breeds and crops already existed and had already arrived (for example, there was no maize in Europe before 1492, and no coffee in Brazil before 1727).

The history module includes hundreds of major events since 1800, including world wars, civil wars, famines, epidemics, economic crises, major earthquakes, and political persecution. Depending on your country and year of birth, they affect your income, health, and risk of death.

Covers 199 countries and regions: all 193 UN member states, plus Taiwan, Palestine, Kosovo, Vatican City, Hong Kong, and Macau. Schooling follows each country's own system and era: starting ages, the names of each stage, entrance and leaving exams, years of compulsory education, and the age of tracking (Germany sorts children at 10) all differ, and peacetime conscription follows each country's actual terms of service. Indicators for each country: annual births, population, life expectancy by sex, infant and under-5 mortality, GDP per capita (PPP), income inequality (Gini), average years of schooling, college enrollment, share of jobs in agriculture, total fertility rate, HIV prevalence, homicide rate, smoking rate, out-of-pocket health spending, child marriage rate, and life satisfaction.

Time of death is drawn from each country's sex-specific life tables (a Gompertz–Makeham model calibrated to national life expectancy); cause of death is drawn from distributions by age and income level. For the past and future worlds, values are simplified from historical trends and UN projections. Income is in purchasing-power-parity (international) dollars.

Figures are rounded approximations meant to show the gaps created by where you're born, not precise predictions.
