Documents

In the course of the I-CeM project various documents, spreadsheets, and datasets, have been created, partly as spinoff’s from the work done, or in order to explain various facets of the data. These are made available here to help users of the I-CeM dataset, but also as stand-alone academic products in their own right. The documents include:

The I-CeM Guide

This is general user manual for the I-CeM dataset covering:

  • the history of British census-taking, 1851-1911;
  • the history of the individual censuses, with lists of the official publications created, and images of the schedules and enumerators books used in the census;
  • the provenance of the I-CeM data;
  • the enrichment programme for the I-CeM data, explaining the processes of reconciliation, reformatting, standardisations, and the creation of inference and enriched variables from the original data;
  • descriptions of all the variables in the I-CeM dataset, including the variable labels, form and length, which census years they cover, their access status, and their possible values;
  • and, means of access to the dataset.

The Guide has a navigation pane for ease of use. To view the .pdf navigation pane, click the Adobe Reader Toolbar icon at the end of the Tools pop up, and then click the 'Bookmarks' icon (second down).

I-CeM Guide version 2

A second, revised version of the I-CeM Guide is now available:

Differences in Population Counts by Parish Table

This shows the difference between the population of parishes found in the raw I-CeM data before reconciliation, and what one would expect from the published Census Reports.

The I-CeM Building Type Dictionary

This gives the text strings relating to building types in the BUILDTYPE variable in the I-CeM dataset, and their relationship to the BTCODE variable – see the I-CeM Guide for definitions.

The Consistent Parish Look Up Table

This identifies the parish(es) of enumeration consistently across all censuses, and is the basis of the CONPARID variable in the I-CeM dataset - see the I-CeM Guide for a definition. This is based on the work of Professor Sir E. A. Wrigley for England and Wales1, and by Professor Michael Anderson for Scotland.

In creating consistent geographies the basic logic is to amalgamate parishes where necessary so that the geographical territory under consideration remains constant over time. So, for example, assume that part of parish A was transferred to parish B between census years. In order to create a consistent geographical unit over time one would need to treat them not as separate parishes, but as a single entity. The reasoning for producing a consistent geography variable is that it facilitates comparisons over time, where, as far as possible, like is being compared to like.

In the case of this project, another important consideration is in that the raw census data have been linked to a geographical information system (GIS) to allow comparable parish-level based maps to be constructed over time. This has been completed in collaboration with Dr Max Satchell and Dr Corinne Roughley, both of the University of Cambridge. For those who wish to undertake their own mapping of the data, the underlying GIS will be available from the project website.

The I-CeM Disability Dictionary

The I-CeM Disability Dictionary gives a listing of the text strings found in the disabilities column (DISAB), and the DISCODE1 and DISCODE2 values they are given in the I-CeM dataset – see the I-CeM Guide for definitions. The DISCODE1 variable is a 7 digit code but the Dictionary only gives the code from the first positive value. Thus, ‘Deaf Dumb Born Like It’ has a value of 0100010 in the dataset, which indicates that information on dumbness and hearing impairment is present, as is information about duration of disability, but there is no information regarding visual impairment, idiocy and imbecility, lunacy, other disabilities, or information relating to severity of disability. But in the Dictionary the string has a value of 100010, the first ‘0’ indicating the absence on information on visual impairment being omitted.

The I-CeM Employment Status Dictionary

The I-CeM Employment Status Dictionary gives the text strings relating to employment status found in the EMPLOY variable in the I-CeM dataset, and the equivalent employment status code EMPLOYCODE – see I-CeM Guide for definitions.

The I-CeM Language Dictionary

This dictionary gives the text strings relating to language spoken in the LANG variable of the I-CeM dataset, and its relationship to the LANGCODE variable – see I-CeM Guide for definitions.

The I-CeM Marital Condition Dictionary

The I-CeM marital Condition Dictionary gives the text strings relating to marital condition in the COND variable of the I-CeM dataset, and their relationship to the MAR coded variable – see I-CeM Guide for definitions.

The I-CeM Number of Rooms Dictionary

This dictionary gives the text strings relating to the number of rooms in the NOOFROOMS variable in the I-CeM dataset, and their relationship to the NOOFROOMSCODE variable – see the I-CeM Guide for definitions.

The Occupational Matrix

The I-CeM Occupational Matrix indicates the position of occupational headings in the occupational tables in the published Census Reports for England and Wales and Scotland for the years 1851 to 1911. Each row of this Matrix gives the position of one occupational heading in the occupational classifications used in the Census Reports for this period. The HISCO coding of each of the occupational headings is also given. Each row is given a number which then becomes the value found in the OCCODE variable in the I-CeM dataset. A more detailed introduction to the Matrix, its construction and uses is available.

The Parish ID for All Years Table

This identifies the ‘parish’ of enumeration listed in the various tables published year by year in the GRO and GRO(S) Census Reports. It is, therefore, not consistent over time. Equally, the same named parish in different years may not cover the same geographical territory, due to boundary changes over time. This is the basis of the PARID variable in the I-CeM dataset – see the I-CeM Guide for a definition. A full list of these parish units in available for each year.

The I-CeM Placelist

This gives a list of all the places, hamlets, townships, etc., given as birthplaces in the I-CeM dataset, with the STD_PAR parish, CNTI county, and ALT_CNTI county, in which they fall. See the I-CeM guide for definitions of these variables.

The I-CeM Relationship to Head Dictionary

This dictionary gives the text strings relating to relationship to head in the RELAT variable in the I-CeM dataset, and how these relate to the codes in the RELA variable – see the I-CeM Guide for definitions.
