In the Late Chiripa phase Chiripa's population index grows to 445, a rate of 0.11%. This is roughly equivalent to the overall Middle Formative population growth rate of 0.13%. Sector D covers 7.7 ha. Early in the Late Chiripa phase the Llusco sunken enclosure was constructed ([Paz Soría 1999]). The Lower Houses date to the middle of the phase, while the Upper Houses and the mound proper (Figures 6.4, 6.6) were later constructions, probably built during the last century of the Late Chiripa phase ([Bandy et al. 1998,Bandy 1999b]). During this phase, Chiripa was one of the four principal villages on the Taraco Peninsula.
