Quick Reference Sheet: Clues Found on United States Census Records

I recently learned that I had passed Level One in my quest for accreditation through ICAPGen. I am very excited to be moving forward in the process! I also learned that I can take the Level 2 and 3 tests next week. That is quick, but I did participate in the Level 2 and 3 study group almost a year ago and have been slowly preparing for these tests ever since. I have spent this week reviewing to ensure that I am really ready.

I did another Level 3 practice test a couple of days ago. This test is a four-hour research project, and I realized that I need to be able to quickly remember which censuses provide clues about different aspects of research subjects’ lives.

Because the tests are timed, I have been creating quick reference sheets so I will have needed information at my fingertips. During my practice test, I wished I had a quick reference sheet to show what information appears on each census. There are resources for this, but the options I have seen list the information by year. I decided it would be helpful to create a quick reference sheet by category (marriage, immigration, etc.). I used the Index of Questions at the Census Bureau Website and FamilySearch’s United States Census Forms examples to create my quick reference sheet, Clues Found on United States Census Records.

This information will help with research planning for any project and I thought you might like to have a copy too. I’ve copied and pasted the information below but also included a link to a pdf version at the end of this post for your convenience. I hope you will find it helpful!
