How the categories split
How values are spread across the records that have one. Use it to check that the attribute tells records apart: when one value holds nearly everyone, it will not separate audiences much. Categories are ranked by share, largest first. “All other values” groups the smallest into one bar.

Coverage
How widely Faraday has this attribute, and how precise its values are. How many of your own records get a value also depends on how many of them Faraday matches. The state map shows where coverage is thin. Coverage over time shows whether it is growing or shrinking.
Coverage by state
Percentage of addresses in each state with a value.
Coverage over time
Share of addresses holding a value at each monthly snapshot. A value carries forward for one year.
How we arrive at a value
Whether a value was observed on the person themselves, carried from their address, or estimated from the people around them.
- On the person — 0%
- Not used for this attribute — no value is inherited this way.
- From address — 100%
- Carried from what we know about the household at their address.
- From geography — 0%
- Not used for this attribute — no value is inherited this way.
Coverage, in context
Where 19.0% sits on the catalog’s own coverage range.
Higher coverage than 35% of address-level attributes in the catalog
Freshness
Whether the values reflect today. A long gap since the latest collection means they may lag behind what is true now.
Collections
How recently this was collected, and how often a new collection arrives. Each bar is one collection, sized by how many addresses it carried. Gaps are real — collection is periodic, not continuous.
