A census has been taken every ten years from 1801. The first four censuses (1801 - 1831) were mainly headcounts and contained little personal information. The 1841 Census was the first to record the names of everyone in a household or institution and from 1851 onward the census shows the stated age and relationship to the head of household for each individual. Only those census over 100 years old are available for use by family historians and can help show family relationships, ages, occupations and place of birth. Currently the last available census is that taken in 1911.
Note that a change in the parish boundary in 1896 meant that part of St. Bartholomew and St. Peter the Great parishes outside Chichester municipal borough, were added to New Fishbourne and this accounts in part for the increase in population.
