My advice is try your best to get as high a response rate as possible,
but recognize that 100% response rates are very hard to achieve.  Valdis
Krebs has excellent suggestions for improving response rates and data
quality in organizations.  Don't despair if you have 75% response rates
since we know at least some measures are robust even with missing data.
 See our paper.

measures when networks are sampled.  Social Networks, 25, 283-307
