The factor that has an impact on communication behavior is social networks.
“The close circle of contacts is composed of about 20 people: 7 in the ‘intimate circle’, 13 in the ‘close circle’. A further 37 are ‘weaker ties’. This core of 20 is a number that’s consistent across countries in Europe and the US.
Who’s in this core? About 60% are ‘given’ contacts (family, schoolmates, work colleagues, neighbours), only 40% are ‘chosen’. If you look with whom people communicate, 3/4 of the contacts happen with the people within those 20 ‘core’ contacts.”
