I do not currently have any specific census records on this site. You can find census information at the following links:

Cyndi's List - Mississippi  

Ancestry.com - Mississippi Census & Voter Lists  

Ancestry.com and FamilySearch.org contain census materials. Ancestry will require a paid subscription, but FamilySearch is free. You can create a free account there and search in their voluminous records for free. It is generally well worth the time and effort to have an account to research for your family.

USGWCensus.org - Mississippi - select from the various counties linked.
