When I load census information, I put the year, followed by location on one line, with the source citation following the location.
On the next line, I put 2 colons :: at the beginning of the line, then 'copy / paste' the family list after the colons, then copy the double colon to the front of each line. That will indent the family list so they are each on separate lines.
The census 'source citation' should be entered as an inline citation using the 'ref" which will remove that portion from the biography.
If you want to add further information, you can add the parents birthplace, following the family member line that it is appropriate for, the majority of the rest of the info is in the family list.
For 1900, I usually go through each family member and add the birth month / year, as well as number of years married for the parents, and the number of children and number living for the mother, adding the appropriate information on the family member line. That keeps the biography concise and together by each person.
