When you get hired on at a job, you will be asked whether you are single or married and whether you have any children.  Why would that be important?  Because the number of people in your family that you are supporting will affect the amount of taxes (federal, state, Medicare) that are taken out and the amount of the medical insurance premium to cover the entire family.  It does not change the amount a person chooses to have put into a retirement savings plan such as a 401K or the amount of percentage of social security tax and Medicare tax.
