Stephen and Julie Gibbon (Gill) - Genealogy Information
We are very grateful for permission from the Surname Profiler Project Website to include images and information on these pages generated from their profile research and data. Many thanks to Daryl Lloyd, Richard Webber and Paul Longley. Their site provides really useful and interesting spatial information relating to surnames. The site provides, for a given surname: frequency and ethnicity data; geographic information; and spatial maps from 1881 and 1998. It is extremely interesting from a genealogy perspective. If you have not tried the Surname Profiler Project Website I can highly recommend it.

| * Meaning of an 'index' : An 'index' shows whether the
level of something is higher in one area than it is in another area. In
this instance we are interested in whether the number of occurrences of
a name per million population is higher in a particular area than it is
elsewhere. Thus we compare the incidence of a name in the US state where
it is most concentrated with the average level of concentration in the
whole of the US; the incidence in Australia's top state with the
Australian average; the incidence in New Zealand's top province with the
New Zealand average; the incidence in GB's top postal area with the GB
average. * Calculation of an 'index' : If a name has a rate per million population in an area which is identical to its rate in a base comparison area then we say it has an index of '100'. An index of '200' for a the name Jenson in Ohio would mean that the name Jenson was twice as common, per million population, in Ohio as it was in the reference area, in this case the whole US. An index of '500' for Wong in Victoria would indicate that the name Wong was five times more common per 1,000,000 names in Victoria than in the whole of Australia. An index of '1000' for the name Penhaligon in New Zealand would mean it was ten times more common per 1,000.000 names in New Zealand than in Great Britain. By contrast an index of only '50' would indicate a name which was only half as common in a target area than in its reference area. |
