Goats per square km. Goat densities were estimated by first calculating average numbers of animals per household from the Lux-Development 1999 population survey data in four zones. These averages were then attached to point data for all rural households (as available from the 1996 Directorate of Surveys and Mapping 1:50 000 mapping project). Densities of goats were then estimated by "spreading" the number at each household over 5 kilometers. ArcView's Spatial Analyst Density function was used with the kernel method. Origin: RAISON.
