Calculate total number of households for the sector

This step is straightforward. The corrected area of the sector (derived in section 4.1.2, above) is divided by the average area of the household compound (the basic residential unit, described in section 4.1.1). Under the point contemporaneity assumption (section 4.1.3) this yields the number of households occupying the site during a phase-specific local maximum (the time of a site's maximum occupied extent within a given chronological phase). As I mentioned in the discussion of section 4.1.2, above, observation and cursory measurement of about a dozen modern Aymara residential compounds yielded an average occupied area of 0.09 hectares per compound. This seems to be consistent with the small set of prehispanic household data which is available in the published literature. I emphasize again that this figure excludes the splash zone as described in section 4.1.2.

The number of households in the sector is calculated using a simple equation:

H = 
$\frac{A_{s}}{A_{h}}$




where H = number of households


		 		 $A_{s}$ = corrected area of sector


		 		 $A_{h}$ = average household compound area
