The complete data set used for the case study is held in Breedsurv - a computer data capture and storage system designed and written in Microsoft Access 2000 by ILRI specifically for SADC Livestock Breed Surveys ( Rowlands et al., 2003). This is briefly described in Case Study 11.

Only the data for the numbers of the different species recorded on Page 1c of the questionnaire (see Case Study 11) are required for this case study. These are stored in a Breedsurv table called HOUSEHOLD.

The livestock numbers have been extracted and copied into duplicate worksheets stored in the Excel 'Data' worksheets in CS12Data1 and CS12Data2. The different field names in these data worksheets are described in CS12Doc.

These two data sets are used for different methods of calculating population estimates.
