Distribution
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. Each bar is a band of values, lowest on the left. The shading groups the bars into percentile bands.
Share by value
Share of postcodes with a known value in each band. The middle 50% falls between 306 and 4,829 count, shaded darkest.
P10 means 10% of postcodes have a value at or below this one, and P90 means 90% do. P25 and P75 bound the middle half. The median is the middle: half are below it, half above.
Median over time
1,276 count → 1,364 count across 4 collections, shaded between P25 and P75. Estimated from a 1% sample of postcodes.
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 postcodes in each state with a value.
Coverage over time
Share of postcodes holding a value at each monthly snapshot. A value carries forward for one year.

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 postcodes it carried. Gaps are real — collection is periodic, not continuous.
Change between collections
How much values move between collections. Income or life events should move; heavy change in something steady can mean noisy data.
of postcodes changed value between the two most recent collections — 6.2× the catalog median of 16.0%.
