No, those numbers are not useful. However, the information you moved to the bottom is not all gobbledy-gook. You have:
- Source: S2 1940 United States Federal Census Ancestry.com Publication: Online publication - Provo, UT, USA: Ancestry.com Operations, Inc., 2012.Original data - United States of America, Bureau of the Census. Sixteenth Census of the United States, 1940. Washington, D.C.: National Archives and Records Administration, 1940. T627
Notes
SEX: SOUR PAGE Year: 1940; Census Place: Highland, Perkins, Nebraska; Roll: T627_2260; Page: 2A; Enumeration District: 68-4 _APID 1,2442::61689967
A better way to present this information is to delete the red words. The blue is Ancestry specific information, meaning Ancestry is where you saw the information. What is printed in black would enable anyone to find the correct census record wherever they look. A better way is to put the original source first, like this:
United States of America, Bureau of the Census. Sixteenth Census of the United States, 1940. Washington, D.C.: National Archives and Records Administration, 1940. T627; database and digital images, "1940 United States Federal Census," Ancestry.com Operations, Inc., 2012 (https://www.ancestry.com : accessed 9 October 2020); citing Year: 1940; Census Place: Highland, Perkins, Nebraska; Roll: T627_2260; Page: 2A; Enumeration District: 68-4 .
The green words I had to type, the rest was copy/paste. In this example, the original information is first, second is the the name of the Ancestry database and their publication info. The last part is the citation info which tells you which census page.
