Who are these people?
By living arrangement
By age
Estimated breakdowns of the same total.
Where in the world?
Regional breakdown of the same estimate: it does not depend on local time.
The twelve-month projection
Twelve-month projection · millions of people.
Method and sources
Ages 18+ · Worldwide · People, not couples. Exploratory estimate, not a live census. The component living apart relies on a particularly uncertain international transfer assumption.
What the data measure
GLAD provides historical age-sex profiles for 107 countries, weighted using World Bank 2024 populations. National profiles cover 88.5% of modeled adults; regional transfers cover the rest. Latest national sources range from 1991 to 2020 (median year: 2011).
Central model assumptions
Partners with separate homes, nearby or far away, form one category. We average LAT / (LAT + single) ratios from ten European countries in a 2015 study and apply this to adults not cohabiting with a partner. Transferring it worldwide and to all adult ages is a CurioStats assumption, not an observed global rate.
Total = adults × cohabitation rate + adults without a cohabiting partner × LAT coefficient. Each person counts once. The remaining 0.35% of the adult population receives the model’s average global rate.
Rises and falls simulate people entering and leaving relationships, not observed events. Entries are calibrated to preserve the demographic trend: deaths are not subtracted twice.
Exits use a 3% annual separation proxy observed in Provence-Alpes-Côte d’Azur (2014–2020), transferred worldwide as an assumption. World 2024 mortality is weighted by the partnered share of all inhabitants; each partnered death removes two people (the deceased and surviving partner). This approximation does not adjust for age at death. Person movements use Poisson draws, distributed within UTC ten-minute windows conditioned on demographic endpoints. The simulation is identical at the same time for everyone; reloading does not reset it.
Each table partitions the same total. Housing categories are exclusive. Men/women follow demographic source categories and do not describe all gender identities. The age and regional distribution of partners living apart is extrapolated using the same coefficient; it is not separately measured.
Twelve-month demographic projection: vertical axis in millions of people, horizontal axis in months. Simulated second-by-second fluctuations are not extrapolated into this curve.
Important limits: old data, varying definitions, limited evidence for non-cohabiting relationships outside studied countries, and incomplete institutional household coverage. Ages 18–19 use the 15–19 profile. A France check differs by about 10% from a national cohabiting-couple count with a different scope. This is neither an official result nor an estimate with a confidence interval.
