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.

Share by category

n = 117,084,035

Share of addresses in each category. 51 categories, of which the 20 largest are shown, with 9.7% in the largest.

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

97.7% today

Share of addresses holding a value at each monthly snapshot. A value carries forward for one year.
