historical research

There are many tools out there for handling census data. Unfortunately, I can't find what I need.

I am looking at a 3 county area in my state and need to find census data from ALL census years. The trickiest thing so far has been finding tools that include data from before 1990.

Ideally, but not absolutely nessecary, I'd like to find a tool that will let me create my own variables. I.e. income of richest %1 of households in a grouping of census tracks.

The reason for this question is that my organization is working on an economic history of our region and would like to compare different industries to population trends.

I'm conducting an oral history about the transformation of Wicca from a occult fascination into an officially-recognized, socio-political community. I have plenty of respondents and there is a wealth of literature on the history of modern Neo-pagan faith communities, but my question is- where can I deposit my research once it is completed?

I've searched for research depositories that focus on religious studies, but I'm still at a loss. None seem to have an open submission policy- they usually limit themselves to students or faculty at the University in question or have been closed.

Any ideas of where I can start searching? Even beyond a religious studies depository, is there some kind of research collection that focuses on counterculture groups or marginalized communities?

Thanks, and keep up the good work!
