Additional notes to explain missing data or anomalies
The national Research and Statistics Department of the Church of England has provided some additional explanatory notes which might help you understand missing data and estimations:
Attendance and Finance data
Attendance and Finance data have been compiled from annual parochial returns. As you may be aware, we do not get a 100% response rate for these each year and the data in these Spotlights do not contain any estimates. The Spotlights are at the parish level, so where there are statistics for multiple churches in a parish, these have been amalgamated. Where there have been pastoral reorganisations, the data may show jumps in figures, or gaps in the data.
These Spotlights have been compiled using our best [national] knowledge of the geographic make-up of the country. The Diocese of Leicester has churches that work outside the parish system, or work in different geographies such as conventional districts or guild churches. These churches may not appear in the list of pdfs, however the population data for the geographic parish overlaying the area will be of relevance. If there are specific areas for which you would like a community focused Spotlight, without annual parochial returns data, or with annual parochial returns data for different churches then please do contact us with further details about these areas. These structures are accurate as at March 2013, however the annual parochial returns data are accurate as of 2011, so in areas of considerable pastoral reorganisation, there may be mismatches between the geography and the churches for which the annual parochial returns data refer. Once again, please do contact us if there are any specific areas for which you would like us to produce a revised Spotlight.
“Centroid” and “non centroid” spotlights
The community data is based on various government sources, including the 2011 census. Government boundaries do not match our ecclesiastical parish boundaries, so best fit modelling is required. The method we have used is to take the smallest geography for which population data is released (called an Output Area), represent that area with a single dot (placed in the middle of where the people live in that area, called a “Centroid”, and then allocate that population to the parish within which the dot falls. This gives the parish its population count and is a standard best-fit modelling technique. It does mean, however, that for some parishes no dot fall into the boundary, so we are not able to allocate a population count. For these parishes we have given some broad percentages to reflect the population instead.
Church Statistics-only Spotlights
There are a number of parishes where we have annual parochial returns data, but we cannot allocate this to a geography on the ground (and therefore community data). This could be due to pastoral reorganisation, or churches that work outside the parish system. We have included these as a series of Spotlights with very limited data for your information. You may wish to distribute these with the relevant geographic areas.
