Here are my Questions (in Red) and Daniel's Answers (in blue):
Q1) What is the source of the census images? Are they from FHL microfilms, or NARA films, or another source?
Q2) Did MyHeritage create an independent index? If so, using paid or volunteer indexers? From which countries? If it's not independent, where did you obtain it?
Q3) Why did you not include the NARA Microfilm Publication number and the NARA Roll number in the indexing? Is the "Roll number" on the record summary an FHL microfilm number?
Q4) How did you choose which fields to index? For instance - for 1880 to 1930, the father's birthplace and mother's birthplace are very useful bits of data, and the Ancestry search can use them to narrow a search.
Q5) Is the 1940 U.S. census completely imaged and indexed? If not, which states not not complete? If not, when will the 1940 census be completely indexed?
Q6) When I'm in a Record Match screen, why can't I click on another person in the household and "Confirm" or "Reject" that match also (if it's in the Record Match list)? In my example today, the husband, mother and two children are all in my MyHeritage tree and I would prefer to Confirm them all by clicking on their name and confirming, rather than having to do it 5 times from five different Record Matches.
Q7) Are the Record Matches finished providing numbers? My number of Record Matches is very low for some census years. My guess is that the search is not complete, and that it will take some time to do everyone's tree. For instance, I have 116 source citations in my tree for the 1850 census, but the Record Matches shows 5. I have 420 sources for the 1900 census, and MyHeritage shows 588, which means I have work to do!
