PartyDemographics characterize a single PartyRole.  There was thought given to describing both PartyDemographics and PartyRoleDemographics.  However, as was done with PartyRoleContacts, having demographics at both the Party and PartyRole seemed to be a bit of over-modeling.  Therefore, if the same demographic characterizes two or more PartyRoles played by the same Party, the demographic is repeated for each role.<br/>PartyDemographics can also be defined in part by a ProductOffering that a Party has obtained and/or used. For example, the number of minutes of long distance used within a Calling Plan offering.<br/>PartyDemographics can also be grouped by GeographicArea and MarketSegment.<br/><br/>
