Sagacity segmentation is a means of segmenting a population of interest using life-cycle stage, income and occupation variables.
The logic behind this segmentation systems is that as people pass through life, their aspirations and behavior patterns (including consumption of goods and services) also change.
[1] Sagacity segmentation was developed by a company trading as Research Services in the early 1980s.
The objective was to gain greater insights from segmentation variables such as the family, occupation, and income.
Sagacity segmentation is most often used by banks and financial institutions because life-stage is perceived to be a major factor in making major financial decisions such as purchasing a car, house or life insurance.
