For the purpose of this short guide, abstracting census data means we collect and record all the important information about each member of the enumerated family. One can use any system they choose, but here is the one we use. You will find abstracts by clicking on the keys for census citatations in personal page footnotes.
To conserve space, many data elements that are common and repetitive are abbreviated. Some abbreviations are quite obvious (e.g., dau for daughter), while the rest are easily learned from the table. Stylistically, we list last name, first name and middle initial (if reported), all in capital letters with no punctuation.

Here is an example of how we might abstract a pre-1850 US census where only the head of household is listed by name. The data in parens is a best guess based on other information about the family.

BISBEE 1 male under 5 (Curtis ae1) 2 males 5 to 9 (Cheney ae5) (Albert ae6) 1 male 30 to 39 (Joseph ae37) 1 female under 5 (Ruth Ann ae2) 1 female 10 to 14 (?Thaddeus ae10?) 1 female 30 to 39 (Sally Ann ae34) 1 female 40 to 49 (Charlotte Taylor ae45) Total of 8 persons, one engaged in agriculture.
