Relationship & Dating Statistics
Data-backed research on dating, marriage, divorce, and relationships, built from primary sources like the CDC, Pew Research, the U.S. Census Bureau, and peer-reviewed studies. Every figure is cited, and we refresh these reports as new data lands.

Methodology
Where These Numbers Come From
We don’t run our own polls. Every number here started somewhere else, usually at a federal agency or a university research group. The work is finding that original release and reading it properly before we quote it.
01
Topic Selection
We choose topics by what people actually search for, then let that shape the outline. If enough people ask how the divorce rate changes with age, that question gets its own section and its own table.
02
Source Vetting
A source counts if it collected the data itself: the CDC, the Census Bureau, Pew, the FBI, a peer-reviewed journal. Law firm blogs and statistics roundups don’t count, however often the rest of the web cites them.
03
Data Extraction
Figures come out of the original release, not out of whoever quoted it second. We record the publisher and the year the data was collected, along with who was actually surveyed. A national rate and a poll of app users answer different questions.
04
Cross-Checking
Then we look for a second source measuring the same thing. When two credible surveys disagree, both figures go in with a note on which population each one covers. Anything that cannot be traced back to a primary source gets cut, even when it is the number everyone else repeats.
05
Building the Report
Each finding becomes one short line with its source and year attached, so it can be quoted without losing the context. Sections close with a table so a figure can be checked without reading the paragraph around it.
06
Review and Refresh
An editor opens every citation again before the report goes live, and the report stays on our update list after that. When the CDC or the Census Bureau puts out a new release, we go back and change the figure and its date.
