Our sources

In brief: every number on this site traces back to a named primary source, listed below, and every widely-repeated figure we could not trace is listed too, with the reason it was turned away.

We only publish numbers we can trace to a primary source: the original study, official statistics, or the organization's own reporting. Secondary retellings, influencer polls, and unattributed "studies show" claims are rejected at the fact-gate.

What makes a source primary?

A primary source is the original report, dataset or dictionary entry a number comes from, rather than an article or listicle that quotes it secondhand. For instance, when this site cites Pew Research Center, 2020, the link goes to Pew's own report page, not to a roundup that mentions Pew.

A probability sample is a survey built so every person in the population has a known chance of being asked, which is what lets a result generalize beyond the people who happened to answer. An opt-in panel is the opposite: people choose to take part, usually because a brand invited its own customers, and the result describes only that self-selected group. Consider a dating app surveying its own users about how long couples waited to meet each other's kids — a real number, but not one that describes daters in general. We reject figures shaped like that; see the rejected list below.

Which sources do these numbers come from?

Below is every publisher currently cited on this site, deduplicated by URL. For example,Pew Research Center, 2020 is the source behind the "friends with benefits" awareness figure quoted above, and it appears once here even though several pages reference it.

What did we reject, and why?

This list matters as much as the one above. These are figures that circulate widely in writing about situationships, the talking stage and modern dating slang, and that we could not trace to a primary source, so they do not appear anywhere on this site.

What rules govern a citation here?

Four rules, applied to every figure before it ships. Rule two is why a lexicographic entry like Dictionary.com, 2026 links straight to the dictionary page rather than to an article describing it.

  1. Named source in the same sentence as the number, with the year.
  2. Primary source only — we link the origin, not an article about it.
  3. Dated verification: every statistic carries its verification date on the statistics page.
  4. Unverifiable → unpublished. No exceptions.
