Although Wyoming wasn't made a state until 1890, it did get enumerated... just not where most of you probably think.  Where then, are you supposed to look for your relatives?  Hopefully, this page will give you the answer; and, if not the answer, then at least a direction.

If emboldened or underlined, you should run your cursor over the place of enumeration to access a particular page.   Hopefully, we have a transcriber (or two, or three) out there who would like to donate their time and efforts to getting some of the censuses online here for everyone.  If you have any censuses you'd like to submit, please contact me.

Dated notes are injected where necessary in between census years.  They should be used as guides to your next census step.  In advance, you might like to know that a red Note: is not a good thing.

Links to an assortment of maps on this site are provided to give you a visual image of at least some of the boundary changes.
