In depth
A census record is a government document recording the population at a specific time, including names, ages, places of birth, occupations, and citizenship status. Census records are taken every 10 years in most countries (US, UK, Canada, etc.).
For CBD cases, census records can establish: (1) the ancestor's residence in a given year, (2) the ancestor's citizenship status ('NA' for naturalized, 'PA' for first papers/declaration of intention, 'AL' for alien), and (3) the year of immigration (often recorded in US censuses from 1900 onward).
US census records are available for 1790-1950 (with 72-year privacy restrictions). UK census records are available for 1841-1921. Canadian census records are available for 1851-1921. These records are available through Ancestry, FamilySearch, and national archives.
