What the Statistics page shows

The Statistics page turns the people and families in your current workspace into an overview of your tree. Open it from the Statistics item in the sidebar. Every person named on the page links to their profile. Click a first name, surname, occupation or religion, or a place in a country's list on the Places tab, to see those people in the Knowledge Base.

The page is split into tabs: Overview, Names, Places, Lifetimes, Families and Ancestry. Your tab and your Everyone / Connected to root choice are kept in the address, so you can bookmark a view.

Everyone, or only your connected tree

If you have set a home person, a switch at the top lets you choose between Everyone in the workspace and Connected to root, which leaves out people who are not linked to your home person (for example a separate branch from an imported GEDCOM file).

Places

Two maps show where people were born (blue) and where they died (purple), each shaded by how many people that is. Click a country in the list under a map to see its individual places. A place counts for the country written at the end of its name (for example "Ulm, Germany") or, if it has none, for where the place is on the map; places with no country we can recognise are listed under Other at the bottom of the list.

Ancestors by generation

Scroll over the ancestor fan, or use its arrows, to move through older generations.

Shared ancestry

This section shows couples in your tree who were related by blood, with their relationship (such as "second cousins") and a percentage. The percentage is the share of ancestry a child of that couple would inherit from the same source twice: 6.25% for first cousins, 1.56% for second cousins. Repeated ancestors shows how often the same person appears more than once in your home person's pedigree, which is common in small or rural communities. The DNA figure next to related couples is an estimate from published averages, not a test result.

How the numbers are counted

  • Only dates with a readable year are used. A person with no birth year is left out of anything that needs one.
  • Living people are left out of lifespan figures.
  • Impossible values, such as a lifespan over 120 years or a parent younger than 12, are treated as data errors and ignored.
  • When several people share a record, the card shows one of them and how many others tie.
