Chiripa Pata is one of the very few sites on the Taraco Peninsula which increased in size during the LF1. Sector C has a population index value of 414 (7.25 ha), as opposed to 277 (5.0 ha) for sector B. This is equates to an annual growth rate of 0.07%, far less than that of the principal LF1 sites (Kala Uyuni, T-232), and slightly below the phase average of 0.08%, but still remarkable in a phase in which most sites lost population.
