It seems to be only for the 1930 and 1940 U.S. Censuses so far, and I hope it eventually covers All of the U.S. Censuses! It would be even more cool if they added that feature to ALL the documents, but that would obviously be TREMENDOUS work!
It is a great feature for beginners because it walks them through every detail that they could miss in those censuses, and it is like having a mini lesson in the details featured in those censuses! It is also just fun for all levels!
You can use this feature by viewing the actual census image.
For the 1930 U.S. Census, they walk you through your ancestor’s home ownership, education, occupation, their home, birthplace, age, radio ownership, and marriage status.
For the 1940 U.S. Census, they walk you through your ancestor’s address, home ownership, household, age, education, birthplace, occupation, hours worked and income.
They also give you links to the street view of the addresses now on Google maps, compare the rental amount or home value from then to now for you, and compare their income then to nowadays!
Of course, the feature may be off on how household members are related, but it can’t do everything! 😉
Go into Ancestry.com, and give it a try now for some fun!
