.. done Age === This Condition is on the Personal tab in Search Builder and allows you to find people based on their age. To find those without an age on their record (which means they have no date of birth) use **Equal** and **do not put anything for the Value**. Here are the comparison options:   Equal Exactly that age at that moment          Greater             Not that age, but greater      GreaterEqual     Equal to that age or greater than  Less                 Not that age, but less than LessEqual         Equal to that age and less than NotEqual           Any age that is not that age    What you use for the Top Group Condition (ALL, ANY, NONE) will obviously change the results, so you need to think carefully about these. Here are some examples using an age range with the Comparisons staying the same (GreaterEqual 30 and LessEqual 40) and the Condition changing. Notice the different results:  Comparision: **>=30 and <=40** Match ALL  Results are just those age 30-40. Match ANY Results are **anyone 30 or older as well as anyone 40 and under**; *excludes* the group from 31-39. Match NONE No results. There will of course not be anyone who is both 30 or older AND also is 40 or younger. To *exclude* one age, add NotEqual 35 as a Condition and you will get everyone from 30-34 and those 36-40.
