I'm not seeing anything in the catalog. https://www.familysearch.org/wiki/en/Zimbabwe_Genealogy
I just tried a search in the 'FamilySearch' "Wiki"
Unfortunately, NOTHING using just "Rhodesia".
A little using "Zimbabwe"; but, NOTHING specific for "Census":
Zimbabwe Online Genealogy Records
Zimbabwe Civil Registration
Zimbabwe Military Records
Zimbabwe Compiled Genealogies
As an aside ...
Due to the nature of your 'Question ...
I am "Moving" this 'Question' of yours, in the 'Group' being "How to Use FamilySearch Community", in this "Community.FamilySearch" Forum, to the 'Group' being "General Questions", in the Forum; so that, the members of that group can answer/assist you.
That Group is "Public", which you can join, if you wish.
As, that 'Group' being "How to Use FamilySearch Community" relates to HOW to USE the "FamilySearch.Community" Forum", rather than for research help/assistance.
As a further aside ...
On the 'off chance" ...
I am ALSO "Tagging" this 'Question' of yours in the 'Group' being "Africa Genealogy Research", in the Forum, in the hope that, the members of that group may be able to answer/assist you.
That Group, is ALSO "Public", which you can join, if you wish.
I hope this helps.
