Which segmentation factor is NOT typically examined in buyer segmentation?

The correct choice highlights that local weather patterns are not typically examined in buyer segmentation. Buyer segmentation primarily focuses on factors that directly relate to the buying behavior and characteristics of customers. These factors usually include aspects such as the size of annual purchase value, the motivations influenced by ownership, and the frequency of purchases.

The size of annual purchase value helps companies understand different buyer categories based on how much they spend. Motivations influenced by ownership reveal insights into the buyer's mindset and can inform marketing strategies. Frequency of purchases provides a view of customer loyalty and engagement.

In contrast, local weather patterns are considered external environmental factors that might affect consumption to some extent but do not directly relate to the individual buyer's behavior or characteristics. Therefore, they are usually not a primary focus in the segmentation process when developing targeted marketing strategies.
