Is there a way to change CENSUS to CENSUS (FAMILY) ??
Census is an individual fact type. Census (Family) is a family fact type. Individual fact types can only be changed to other individual fact types. Family fact types can only be changes to other family fact types.
In any case, the Census (Family) fact type is much discussed on these forums because it often does not produce the results expected by the user. Family fact types such as Marriage and Divorce really only apply to the couple (the spouses), not to the whole family. The Census (Family) fact type is no different. It only applies to the couple, not to the whole family. It's fine to use it if that meets you needs, but you may find that it doesn't meet your needs. One workaround that some users have reported is to use the Census (Family) fact type and then to share it with the children. Depending on what you need to do, that might work for you. You will need to experiment to see what these things look like in reports.
