The number of surveys to send out depends on how many employees you have and what rate of response you are likely to achieve. If you have a relatively small number of employees, you might need to send out surveys to everyone. If you have over several thousand employees, you would need only 500-600 completed surveys to have fairly reliable results for your population as a whole, assuming the respondents accurately reflect the demographics of the entire group. So, if you expect to have a 100% response rate, you would mail out surveys to a random sample of 600. More realistically, if you typically have a response rate of 50%, you'd need to survey 1,200 people (600 divided by 0.5).

Abstract: The number of surveys to send out depends on how many employees you have and what rate of response you are likely to achieve. If you have a relatively small number of employees, you might need to send out surveys to everyone. If you have over several thousand employees, you would need only 500-600 completed surveys to have fairly reliable results for your population as a whole, assuming the respondents accurately reflect the demographics of the entire group. So, if you expect to have a 100% response rate, you would mail out surveys to a random sample of 600. More realistically, if you typically have a response rate of 50%, you'd need to survey 1,200 people (600 divided by 0.5).
