Answer:
A. political affiliation.
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
All of the following factors such as gender, education, age and income level influence migration selectivity except political affiliation.
This ultimately implies that, political affiliation such as the political party that an individual or group of people belong to do not influence or inform their decision to move out of a particular geographical location or area to another.
