STEP 9. HOUSEHOLD DATA SHEETS
9.1 Rationale for using household data sheets
Household data sheets are an add-on feature of P3DM for DRR that gives communities an entire GIS made of spatial and tabular data. This is without requiring any computer hardware and software, which are most often beyond the reach of marginalized communities.
The rationale for using household data sheets is that, in most cases, not all household information can be plotted on a 3D map. This is for two reasons. Firstly, there is not enough space for the pushpins, yarns, and paints to depict all household information especially in the case of large-scale 3D map or if the households are concentrated in a particular part of the 3D map. For instance, it is often hardly possible to plot all children in the community using pushpin but only those children that are malnourished or below a certain age. Yet, for DRR and in facing an actual disaster, a comprehensive set of data is essential.
Secondly, there are some household data that cannot be shown in the 3D map but are equally important information. For instance, data pertaining for example to single parenthood, gender minorities or household violence, are pertinent data but those persons might be ashamed to be pinpointed on the 3D map. In some context, the law also prevents private and individual data being revealed to the larger public.
Whatever the reason is for not plotting particular information on the 3D map, it can still be stored on a household data sheet. The primary objective of the household data sheet is therefore to associate more data to a single household.
9.2 Using household data sheets
Household data sheets compile and list data for each household which is plotted on the map through the use of pushpins. A number is assigned to each household on the 3D map and written on the top / side of the pushpin or on a small piece of paper affixed on the pushpin (Figures 47 and 48). This number is eventually reported on the data sheet (Box 3). Additional information for that household is then listed and available when needs arise, for example, in time of action planning (Table 11).
