Registration districts were originally created for the registration of births, marriages and deaths, rather than specifically for the census. In many cases, registration districts were broadly equivalent to parishes, but not necessarily so.

The Total column shows the total number of people in that county or town with this surname. For example, there were 1,019 people called CULLOM in Tadley at the time of the 1881 census.
The Frequency column shows the percentage of people in this county or town with this surname. For example, a frequency of 22500.0000 in Tadley means that 22500.0000% of the people in Tadley on census day were called CULLOM.
The Index column shows the relative probability of finding someone called CULLOM in this county or town, compared with the probability of finding them anywhere in Britain as a whole. An index of 1 means that if you pick someone at random from this county or town, you have exactly the same probability of picking someone called CULLOM as if you picked at random from the whole of the UK. Where the index is higher than 1, then you are more likely to find someone called CULLOM here than if you picked from the UK as a whole, and where it's lower then you are less likely. The actual figure shows the level of probability - for example, a figure of 2 would indicate that you are twice as likely to find someone called CULLOM here than in the UK as a whole, and 10 would make it ten times as likely. The value of 1.02 in Tadley means that you are 1.02 times as likely to find someone with the surname of CULLOM in Tadley than you would be in the whole of the UK.
