   This paper examines the characteristics of middle class Tehranis'
   networks, based upon a survey of 318 individuals from the 159
   households. The results show that women and men have similar-size
   networks. However, their networks differ substantially in gender
   composition, with each having almost two-thirds of network members of
   their own gender. Men's and women's networks contain a large proportion
   of kin overall. Most ties tend to be with immediate kin: children,
   parents and siblings. An immediate kin is usually the socially closest
   member of a network. Apart from voluntary factors, the importance of
   kinship ties in men's and women's networks may be the result of the
   macro-structural conditions under which patterns of social
   relationships take place. (c) 2007 Published by Elsevier B.V.
