Affinity Index

The Affinity Index indicates the size of reach in a certain target group in relation to the total viewership (market share in the target group as a percentage of the total market share). This index makes it possible to draw conclusions as to whether a given target group has watched a programme, commercial break or time slot more or less frequently than the total audience. For example, an Affinity Index of 140 means that the market share of a certain target group is 40% higher than that of the overall audience.
